Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Support for avoidance of vertical tracks in low metal techs.
* New: In NetBuilderHybridVH::_do_1G_xM1_1PinM1(), added configuration
to manage pins on the north/south sides for VH,2RL.
* Bug: In NetBuilderHybridVH::doRp_xG_xM1_xM3(), correct misplaced
vertical creation (buildind invalid topologies).
* New: EtesianEngine::toColoquinte(), display histograms of the cells
widths (in pitch) before and after bloating to get a better feeling
of the behavior.
* New: In EtesianEngine, add support for track avoidance. Portions of
tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.
* New: In Etesian::Area, Slice and SubSlice, add support for track
avoidance. Exported to the Python wrapper.
* New: SubSlice::getUsedVTracks() to get a set of tracks blocked by
the cell.
* New: SubSlice::trackAvoid(), shift left/rigth the cell under the
requested vertical track. Try only to move the cell under the
track and not it's neighbor, so it assume that there is sufficient
space left or right of the cell.
* Bug: In cumulus/plugins.block.configuration.BlockConf, the Cfg
parameters may be read too early from the Cfg space into the
various sub-conf objects (like FeedsConf). Delay the reading
of the parameters in a _postInit() functions.
Modify Block and CoreToChip to call _postInit().
* New: In cumulus/plugins.block.configuration.BlockConf._loadRoutingGauge,
allow the cell gauge name to differ from the routing gauge name.
* New: In cumulus/plugins.block.configuration.FeedsConf, allow to
select the default feed to be used with 'etesian.defaultFeed'
parameter.
* New: In cumulus/plugins.block.spares.BufferPool, allow to control
whether or not we want tie to either side of the pool.
(for latch up).
* New: In cumulus/plugins.block.HTree._connectLeaf(), add support
for track avoidance.
* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.

Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.

# include "coloquinte/circuit.hxx"
Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

# include "coloquinte/legalizer.hxx"
Migration towards Python3, first stage: still based on C-Macros.
* New: Python/C++ API level:
* Write a new C++/template wrapper to get rid of boost::python
* The int & long Python type are now merged. So a C/C++ level,
it became "PyLong_X" (remove "PyInt_X") and at Python code
level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
* Configuration is now integrated as a Hurricane component,
makes use of the new C++/template wrapper.
* vlsisapd is now defunct. Keep it in the source for now as
some remaining non essential code may have to be ported in
the future.
* Note: Python code (copy of the migration howto):
* New print function syntax print().
* Changed "dict.has_key(k)" for "k" in dict.
* Changed "except Exception, e" for "except Exception as e".
* The division "/" is now the floating point division, even if
both operand are integers. So 3/2 now gives 1.5 and no longer 1.
The integer division is now "//" : 1 = 3//2. So have to carefully
review the code to update. Most of the time we want to use "//".
We must never change to float for long that, in fact, represents
DbU (exposed as Python int type).
* execfile() must be replaced by exec(open("file").read()).
* iter().__next__() becomes iter(x).__next__().
* __getslice__() has been removed, integrated to __getitem__().
* The formating used for str(type(o)) has changed, so In Stratus,
have to update them ("<class 'MyClass'>" instead of "MyClass").
* the "types" module no longer supply values for default types
like str (types.StringType) or list (types.StringType).
Must use "isinstance()" where they were occuring.
* Remove the 'L' to indicate "long integer" (like "12L"), now
all Python integer are long.
* Change in bootstrap:
* Ported Coriolis builder (ccb) to Python3.
* Ported Coriolis socInstaller.py to Python3.
* Note: In PyQt4+Python3, QVariant no longer exists. Use None or
directly convert using the python syntax: bool(x), int(x), ...
By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
* In order to compile user's must upgrade to my own rebuild of
PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
buffer of the H-Tree to the original signal (mainly: top clock).
Strangely, it was only done when working in full chip mode.

Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Support for placing *one* block of a Cell in Etesian.
* Change: In Hurricane::Cell_LeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell_NonLeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell:
getLeafInstanceOccurrences() and getNonLeafInstanceOccurrences(), now
have a parameter Instance* to select the leafs we want to walk through.
If set NULL (default value) browse through all the instances,
as before.
* Change: In Hurricane::DeepNet, add forgotten Inspector support.
* New: In EtesianEngine, add a "block" (and Instance) attribute to allow
the placement of one specific bloc. If we want to place the core of
a chip and take into account the external terminals (if they are not
already fixed as Pins at the edge of *said* block). We must place
the core *in the context* of it's instanciation in the corona.
Note for G. Gouvine : Pin & external RP should be taken into account
starting at line 629 of EtesianEngine.cpp...
* New: In cumulus/plugins/chip/Chip.py, make use of the new block
placement feature of ETesian.
* Bug: In KatanaEngine::create(), perform a pre-check to prevent trying to
route whole chip, which is forbidden an leads to annoying core-dumps.
Routing must take place "at most" at Corona level.
* Bug: In KatanaEngine::PowerRails, create a plane for METAL1 blockage.
Not completely sure this was a bug...

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

# include "hurricane/UpdateSession.h"
First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.

# include "hurricane/viewer/CellWidget.h"
Better handling of exceptions between C++ & Python. Misc. checks.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.
Remove the code of the old Vst driver.
In Blif parser, check for non-existent models (incomplete or
corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.

Support for avoidance of vertical tracks in low metal techs.
* New: In NetBuilderHybridVH::_do_1G_xM1_1PinM1(), added configuration
to manage pins on the north/south sides for VH,2RL.
* Bug: In NetBuilderHybridVH::doRp_xG_xM1_xM3(), correct misplaced
vertical creation (buildind invalid topologies).
* New: EtesianEngine::toColoquinte(), display histograms of the cells
widths (in pitch) before and after bloating to get a better feeling
of the behavior.
* New: In EtesianEngine, add support for track avoidance. Portions of
tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.
* New: In Etesian::Area, Slice and SubSlice, add support for track
avoidance. Exported to the Python wrapper.
* New: SubSlice::getUsedVTracks() to get a set of tracks blocked by
the cell.
* New: SubSlice::trackAvoid(), shift left/rigth the cell under the
requested vertical track. Try only to move the cell under the
track and not it's neighbor, so it assume that there is sufficient
space left or right of the cell.
* Bug: In cumulus/plugins.block.configuration.BlockConf, the Cfg
parameters may be read too early from the Cfg space into the
various sub-conf objects (like FeedsConf). Delay the reading
of the parameters in a _postInit() functions.
Modify Block and CoreToChip to call _postInit().
* New: In cumulus/plugins.block.configuration.BlockConf._loadRoutingGauge,
allow the cell gauge name to differ from the routing gauge name.
* New: In cumulus/plugins.block.configuration.FeedsConf, allow to
select the default feed to be used with 'etesian.defaultFeed'
parameter.
* New: In cumulus/plugins.block.spares.BufferPool, allow to control
whether or not we want tie to either side of the pool.
(for latch up).
* New: In cumulus/plugins.block.HTree._connectLeaf(), add support
for track avoidance.
* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.

* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).

Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:

* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
2014-03-22 05:50:36 -05:00
Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

* Bug: In NetBuilderHybridVH::doRp_xG_xM1_xM3(), correct misplaced
vertical creation (buildind invalid topologies).
* New: EtesianEngine::toColoquinte(), display histograms of the cells
widths (in pitch) before and after bloating to get a better feeling
of the behavior.
* New: In EtesianEngine, add support for track avoidance. Portions of
tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.
* New: In Etesian::Area, Slice and SubSlice, add support for track
avoidance. Exported to the Python wrapper.
* New: SubSlice::getUsedVTracks() to get a set of tracks blocked by
the cell.
* New: SubSlice::trackAvoid(), shift left/rigth the cell under the
requested vertical track. Try only to move the cell under the
track and not it's neighbor, so it assume that there is sufficient
space left or right of the cell.
* Bug: In cumulus/plugins.block.configuration.BlockConf, the Cfg
parameters may be read too early from the Cfg space into the
various sub-conf objects (like FeedsConf). Delay the reading
of the parameters in a _postInit() functions.
Modify Block and CoreToChip to call _postInit().
* New: In cumulus/plugins.block.configuration.BlockConf._loadRoutingGauge,
allow the cell gauge name to differ from the routing gauge name.
* New: In cumulus/plugins.block.configuration.FeedsConf, allow to
select the default feed to be used with 'etesian.defaultFeed'
parameter.
* New: In cumulus/plugins.block.spares.BufferPool, allow to control
whether or not we want tie to either side of the pool.
(for latch up).
* New: In cumulus/plugins.block.HTree._connectLeaf(), add support
for track avoidance.
* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Better handling of exceptions between C++ & Python. Misc. checks.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

More generic H-Tree support to accomodate the LS180 PLL internal clock.
The H-Tree support is now allowed for any net, not only the clocks and
not only top-level nets. This allow to better management of the LS180
internal clock signal.
* New: In Cell::flattenNets(Instance*,set<string>,uint64_t) new overload
of the function to allow the user to select nets that will *not*
be flattened. This makes the NoClockFlatten flag effectively obsolete,
we keep it for backward compatibility.
The net names can be of non top level ones. In that case, they must
use the name an HyperNet will get (the Occurrence name). For example:
"instance1.instance2.deep_net_name".
* New: In PyCell, update the wrapper for the new parameter of flattenNets(),
new utility function pyListToStringSet() to translate a Python list into
a C++ set of names.
* New: In EtesianEngine, add support for a list of nets to be excluded
from the flattening procedure. Those excluded nets will also be
excludeds from the Coloquinte nets *and* HFNS synthesis, as they
are likely to be manageds by a H-Tree.
* Change: In AnabaticEngine::_loadGrByNet(), now also skip nets that are
flagged as manually detailed route.
* New: In AnabaticEngine::antennaProtect(), do not try to insert diodes
on nets that are already fixed or detaled route. This replace the
clock exclusion.
* New: In cumulus/plugins.{block,htree,chip}, replace the concept
of clock-tree by the more generic H-Tree. That is, we can ask the P&R
to create H-Tree on any net of the design, not only the ones matcheds
as clock. The net does not even need to be top-level.
This is to manage the PLL internal clock generated by the PLL in
the LS180 chip.
Start to change all reference to "clock" into "H-Tree".
* Bug: In cumulus/plugins.chip.powerplanes.Builder._connectHTree(),
there was an inversion of the H & V routing gauges to compute the
track into which put the H-Tree center to corona edge wiring.
This was causing tracks to be used twice, seen in the ao68000 test
bench.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Apaired segments building for symmetric routing (step 1).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
unsigned int because we start to need more than 32 different flags
in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
measurements) displaced from Katabatic. This way all ToolEngine
can use this feature. The _postCreate() method display the
memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
builtin timer (remove the local one). Forgot to call the base
class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
Collection allows a deterministic walkthough *all* the AutoSegments
connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
AutoContactTerminal is the *only one* anchored on a RoutingPad,
thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
Created new class DataSymmetric to store symmetric information
of a net (mainly the paired AutoSegments).
Added KatanaEngine::runSymmetricRouter(), for now only build
the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
symmetric information building the non-symmetric routing.

no reason to disallow it and we need it now.
* New: In Hurricane, in Cell::flattenNets(), add a new option to prevent
the flattening of the clock net(s). For more safety perform the
DeepNet creation *outside* the Collection loop.
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences, skip the
DeepNets because they are the result of another flattening operation.
* New: In Isobar, in PyBasicLayer, export C++ method getBlockageLayer().
* New: In Isobar, in PyRoutingGauge, export C++ method getLayerPitch(),

* New: In Etesian, EtesianEngine::findYSpin() to look for the Y orientation
if some cells are already placed. Typically the buffers of a clock
tree.
Pass the correct orienation to row_compatible_orientation().
Do not try to add feeds in the ISPD05 benchmarks. For now the
benchmarks are detected through their names (unreliable).
* Change: In Knik, in KnikEngine::initGlobalRouting(), allow the clock
to be routed as an ordinary signal when the clock tree is not
used.
* New: In Kite, in BuildPowerRails, management & detection for the
pre-routed clock.
In KiteEngine constructor, early initialization of the blockage
net to avoid later troubles in BuildPowerRails.
* New: In Cumulus, in ChipPlugin, add support for Etesian plus new
configuration parameter 'clockTree.placerEngine' to select between
Mauka and Etesian.
* New: In Cumulus, in BlockCorona, add blockages in the vertical sides
in the vertical layer to prevent the router to use the vertical
tracks in under the prower lines (for example, blockage in M3
with power line M5).
In Cumulus, in ChipConf add attribute to access the blockage net.
* New: In Cumulus, when the clock tree is disabled, do not generate
the last rail around the block (the clock rail).
* Bug: In Cumulus, in ChipConf use the clock pad to guess the clock
signals and *not* the power pad.
Add more meaningful error messages if a pad global signal is
not found (implicit connexion by name).
* Bug: In Cumulus, in ClockTree, compute correctly the cells Y spin,
that is *from the bottom of the cell AB* (not from 'zero').

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.

until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).
2019-07-28 16:20:00 -05:00
Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.
2017-11-26 13:31:38 -06:00
string feedNames = getConfiguration ( ) - > getFeedNames ( ) ;
char separator = ' , ' ;
Change in feed & tie managements to fill the empty row spaces.
* Change: In EtesianEngine::_postCreate(), issue a warning if the list of
feeds is empy (configuration: "cfg.etesian.feedNames").
* New: Add a FeedCeels::getFeedByWidth() method to get feeds by their
width in DbU::Unit and not only pitches.
* Change: In Placement::Slice::fillHole(), invert the tie filling and
feeds filling stage. Now we first try to fill the row hole with
feeds, using the widest first, and if they are not configured or
too wide, use the tie.
As the tie *should* also be integrated in the feed list, we may
suppress altogether the fallback tie filling step. Keep it for now.
* Change: In Placement::slice::createDiodeUnder(), the inserted diode
*may* be smaller than the feed it replace. So, in this case, add
a complementary feed to fill the gap.
NOTE 1: Out of lazyness, we add only *one* complementary filler
cell. So there *must* be one of a width wich correspond
exactly to the difference between the original feed and
the diode. Otherwise, gap will remains.
NOTE 2: With wider feed cells, they may cross the GCell border.
But we must insert the diode under the GCell, otherwise
the global routing will be defective. So, for now, reject
feeds that cross the boundary. Must be done more smartly
by inserting the diode over the left or right side of
the feed.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.

EtesianEngine * EtesianEngine : : create ( Cell * cell )

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

the RSMT and insert diodes.

Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.

post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Apaired segments building for symmetric routing (step 1).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
unsigned int because we start to need more than 32 different flags
in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
measurements) displaced from Katabatic. This way all ToolEngine
can use this feature. The _postCreate() method display the
memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
builtin timer (remove the local one). Forgot to call the base
class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
Collection allows a deterministic walkthough *all* the AutoSegments
connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
AutoContactTerminal is the *only one* anchored on a RoutingPad,
thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
Created new class DataSymmetric to store symmetric information
of a net (mainly the paired AutoSegments).
Added KatanaEngine::runSymmetricRouter(), for now only build
the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
symmetric information building the non-symmetric routing.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.

format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.

Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
2015-02-13 16:38:55 -06:00
void EtesianEngine : : setDefaultAb ( )
{
Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.

* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

DbU : : Unit bloatLength = _bloatCells . getDxSpace ( ) ;
double bloatMargin = ( ( double ) cellLength / ( double ) ( cellLength - bloatLength ) ) - 1.0 ;
Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.

* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same
process.

Better handling of exceptions between C++ & Python. Misc. checks.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.
Remove the code of the old Vst driver.
In Blif parser, check for non-existent models (incomplete or
corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.

First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Support for avoidance of vertical tracks in low metal techs.
* New: In NetBuilderHybridVH::_do_1G_xM1_1PinM1(), added configuration
to manage pins on the north/south sides for VH,2RL.
* Bug: In NetBuilderHybridVH::doRp_xG_xM1_xM3(), correct misplaced
vertical creation (buildind invalid topologies).
* New: EtesianEngine::toColoquinte(), display histograms of the cells
widths (in pitch) before and after bloating to get a better feeling
of the behavior.
* New: In EtesianEngine, add support for track avoidance. Portions of
tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.
* New: In Etesian::Area, Slice and SubSlice, add support for track
avoidance. Exported to the Python wrapper.
* New: SubSlice::getUsedVTracks() to get a set of tracks blocked by
the cell.
* New: SubSlice::trackAvoid(), shift left/rigth the cell under the
requested vertical track. Try only to move the cell under the
track and not it's neighbor, so it assume that there is sufficient
space left or right of the cell.
* Bug: In cumulus/plugins.block.configuration.BlockConf, the Cfg
parameters may be read too early from the Cfg space into the
various sub-conf objects (like FeedsConf). Delay the reading
of the parameters in a _postInit() functions.
Modify Block and CoreToChip to call _postInit().
* New: In cumulus/plugins.block.configuration.BlockConf._loadRoutingGauge,
allow the cell gauge name to differ from the routing gauge name.
* New: In cumulus/plugins.block.configuration.FeedsConf, allow to
select the default feed to be used with 'etesian.defaultFeed'
parameter.
* New: In cumulus/plugins.block.spares.BufferPool, allow to control
whether or not we want tie to either side of the pool.
(for latch up).
* New: In cumulus/plugins.block.HTree._connectLeaf(), add support
for track avoidance.
* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.

More clever way of taking into account constraints on caged terminals.
* Change: In vlsispad, in Dots, add an enable/disable flag because when printing
into a cmess, it is only the base class ostream which is took into account
as none of it's methods are virtuals (silly me).
* Bug: In Etesian, print into cmess instead of cout and make use of the Dots
enabling feature.
* New: In Katabatic, added AutoContact::migrateConstraintBox() to transfert
constraint from one contact to another.
New flag for AutoContact, CntWeakTerminal for AutoContact which are at
the other of a segment directly connected to a terminal. They may hold
special constraints in case of caged terminals (computed in Kite).
In AutoHorizontal & AutoVertical, in ::_makeDogleg(), transfert flags
and constraints when breaking a segment directly connected to a terminal.
* New: In Kite, in protectCagedTerminals(), uses cross constraint on the
AutoContact opposite to the ContactTerminal (CntWeakTerminal) instead
of moving up one terminal over two consecutives. This is simpler without
degrading the routing quality.

Support for placing *one* block of a Cell in Etesian.
* Change: In Hurricane::Cell_LeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell_NonLeafInstanceOccurrences, add the ability to
walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell:
getLeafInstanceOccurrences() and getNonLeafInstanceOccurrences(), now
have a parameter Instance* to select the leafs we want to walk through.
If set NULL (default value) browse through all the instances,
as before.
* Change: In Hurricane::DeepNet, add forgotten Inspector support.
* New: In EtesianEngine, add a "block" (and Instance) attribute to allow
the placement of one specific bloc. If we want to place the core of
a chip and take into account the external terminals (if they are not
already fixed as Pins at the edge of *said* block). We must place
the core *in the context* of it's instanciation in the corona.
Note for G. Gouvine : Pin & external RP should be taken into account
starting at line 629 of EtesianEngine.cpp...
* New: In cumulus/plugins/chip/Chip.py, make use of the new block
placement feature of ETesian.
* Bug: In KatanaEngine::create(), perform a pre-check to prevent trying to
route whole chip, which is forbidden an leads to annoying core-dumps.
Routing must take place "at most" at Corona level.
* Bug: In KatanaEngine::PowerRails, create a plane for METAL1 blockage.

without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into

hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.

cmess1 < < " - Building RoutingPads (transhierarchical) " < < endl ;
Implementation of DataBase native save/restore in JSON (step 1).
* New: In Hurricane, added first support for DataBase native import/export
using JSON.
We choose RapidJSON, in SAX mode, to manage the JSON format low level
Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
must be added under ~/coriolis-2.x/src and manually build and installed
in the Coriolis installation tree (to be integrated in ccb later).
Two mode are being supported:
1. Cell mode: one Cell only is saved. In that mode, Entities
referred by Occurrences are "outside" the file. They are coded
through their "signature" (mostly, all the values of their
attributes). The ids saved in the file cannot be restored
identically as we cannot predict when and in which context the
Cell will be reloaded.
2. Design Blob mode: the whole design hierarchy, down and including
the standard cells is saved. This way the design is completly
self contained and Entities ared referred through their ids.
A design blob can only be loaded immediatly after starting cgt
as the DataBase *must* be empty. This way we restore the whole
design hierarchy with *exactly* the same ids.
Now, Hurricane object should provide a "toJson()" method for driving
JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
to allow the hierarchical access of a Cell/Library in native mode
(i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
JSON Design Blobs. Added at this level because we consider it as the
"native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
it's master Cell, we forgot about the Occurrences (through shared pathes).
When an instance is cloned the Shared pathes still points toward the
original Instance. And when it's the master Cell that is uniquifyed
it's the Entities pointed to that remains in the original Cell.
This is a software design problem. It is difficult to define what
policy to adopt when uniquifying: basically that means that one
Occurence is either moved onto the clone or duplicated. Furthermore,
it is not trivial to known what Occurrence is pointing on the
uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
RoutingPads *after* uniquifying (through slaving bounding boxes).
This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
processing the placement so they are put into the right quadtree.
This problem is due to the fact that the RoutingPads do not belong
to the Instance that they refer. And when this instance is moved
around, she doesn't inform the RoutingPad that is has moved.
More software architecture design to review...

//getCell()->flattenNets( Cell::Flags::BuildRings|Cell::Flags::NoClockFlatten );
Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

//getCell()->flattenNets( getBlockInstance(), Cell::Flags::NoClockFlatten );
More generic H-Tree support to accomodate the LS180 PLL internal clock.
The H-Tree support is now allowed for any net, not only the clocks and
not only top-level nets. This allow to better management of the LS180
internal clock signal.
* New: In Cell::flattenNets(Instance*,set<string>,uint64_t) new overload
of the function to allow the user to select nets that will *not*
be flattened. This makes the NoClockFlatten flag effectively obsolete,
we keep it for backward compatibility.
The net names can be of non top level ones. In that case, they must
use the name an HyperNet will get (the Occurrence name). For example:
"instance1.instance2.deep_net_name".
* New: In PyCell, update the wrapper for the new parameter of flattenNets(),
new utility function pyListToStringSet() to translate a Python list into
a C++ set of names.
* New: In EtesianEngine, add support for a list of nets to be excluded
from the flattening procedure. Those excluded nets will also be
excludeds from the Coloquinte nets *and* HFNS synthesis, as they
are likely to be manageds by a H-Tree.
* Change: In AnabaticEngine::_loadGrByNet(), now also skip nets that are
flagged as manually detailed route.
* New: In AnabaticEngine::antennaProtect(), do not try to insert diodes
on nets that are already fixed or detaled route. This replace the
clock exclusion.
* New: In cumulus/plugins.{block,htree,chip}, replace the concept
of clock-tree by the more generic H-Tree. That is, we can ask the P&R
to create H-Tree on any net of the design, not only the ones matcheds
as clock. The net does not even need to be top-level.
This is to manage the PLL internal clock generated by the PLL in
the LS180 chip.
Start to change all reference to "clock" into "H-Tree".
* Bug: In cumulus/plugins.chip.powerplanes.Builder._connectHTree(),
there was an inversion of the H & V routing gauges to compute the
track into which put the H-Tree center to corona edge wiring.
This was causing tracks to be used twice, seen in the ao68000 test
bench.

First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same
process.

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

if ( CatalogExtension : : isFeed ( masterCell ) ) {
Migration towards Python3, first stage: still based on C-Macros.
* New: Python/C++ API level:
* Write a new C++/template wrapper to get rid of boost::python
* The int & long Python type are now merged. So a C/C++ level,
it became "PyLong_X" (remove "PyInt_X") and at Python code
level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
* Configuration is now integrated as a Hurricane component,
makes use of the new C++/template wrapper.
* vlsisapd is now defunct. Keep it in the source for now as
some remaining non essential code may have to be ported in
the future.
* Note: Python code (copy of the migration howto):
* New print function syntax print().
* Changed "dict.has_key(k)" for "k" in dict.
* Changed "except Exception, e" for "except Exception as e".
* The division "/" is now the floating point division, even if
both operand are integers. So 3/2 now gives 1.5 and no longer 1.
The integer division is now "//" : 1 = 3//2. So have to carefully
review the code to update. Most of the time we want to use "//".
We must never change to float for long that, in fact, represents
DbU (exposed as Python int type).
* execfile() must be replaced by exec(open("file").read()).
* iter().__next__() becomes iter(x).__next__().
* __getslice__() has been removed, integrated to __getitem__().
* The formating used for str(type(o)) has changed, so In Stratus,
have to update them ("<class 'MyClass'>" instead of "MyClass").
* the "types" module no longer supply values for default types
like str (types.StringType) or list (types.StringType).
Must use "isinstance()" where they were occuring.
* Remove the 'L' to indicate "long integer" (like "12L"), now
all Python integer are long.
* Change in bootstrap:
* Ported Coriolis builder (ccb) to Python3.
* Ported Coriolis socInstaller.py to Python3.
* Note: In PyQt4+Python3, QVariant no longer exists. Use None or
directly convert using the python syntax: bool(x), int(x), ...
By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
* In order to compile user's must upgrade to my own rebuild of
PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
buffer of the H-Tree to the original signal (mainly: top clock).
Strangely, it was only done when working in full chip mode.

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).

Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.

Correctly manage clock net isolateds from the main clock.
* New: In Bootstrap, in ccb.py, check if cmake is installed and issue
a warning, if not.
* New: In Hurricane, added Cell::getDeepNet() to search for a deepnet
given a path and a leaf net. This method is slow and must not be
used too often. Introduced for Kite::BuildPowerRails().
* Change: In CRL Core, in cmos/alliance.conf, modify the clock name
pattern to match the sub-clock signals in the datapath operators.
* Bug: In Etesian, do not blindly reset the top cell abutment-box.
Do it only if it's empty, otherwise keep it.
* Bug: In Kite, in buildPowerRails(), in getRootNet() the management
of clock nets was incomplete. The case of unrouted clock nets
that where not connected to the top core clock net, like the
one in the datapath registers was faulty. They were partly
recognized as unrouteds and partly as blockage generating a
routing deadlock: routage impossible due to blockage generated
from itself...

the model generation and allow a call by the model name (string).

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
2014-03-22 05:50:36 -05:00
Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.

with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same

More generic H-Tree support to accomodate the LS180 PLL internal clock.
The H-Tree support is now allowed for any net, not only the clocks and
not only top-level nets. This allow to better management of the LS180
internal clock signal.
* New: In Cell::flattenNets(Instance*,set<string>,uint64_t) new overload
of the function to allow the user to select nets that will *not*
be flattened. This makes the NoClockFlatten flag effectively obsolete,
we keep it for backward compatibility.
The net names can be of non top level ones. In that case, they must
use the name an HyperNet will get (the Occurrence name). For example:
"instance1.instance2.deep_net_name".
* New: In PyCell, update the wrapper for the new parameter of flattenNets(),
new utility function pyListToStringSet() to translate a Python list into
a C++ set of names.
* New: In EtesianEngine, add support for a list of nets to be excluded
from the flattening procedure. Those excluded nets will also be
excludeds from the Coloquinte nets *and* HFNS synthesis, as they
are likely to be manageds by a H-Tree.
* Change: In AnabaticEngine::_loadGrByNet(), now also skip nets that are
flagged as manually detailed route.
* New: In AnabaticEngine::antennaProtect(), do not try to insert diodes
on nets that are already fixed or detaled route. This replace the
clock exclusion.
* New: In cumulus/plugins.{block,htree,chip}, replace the concept
of clock-tree by the more generic H-Tree. That is, we can ask the P&R
to create H-Tree on any net of the design, not only the ones matcheds
as clock. The net does not even need to be top-level.
This is to manage the PLL internal clock generated by the PLL in
the LS180 chip.
Start to change all reference to "clock" into "H-Tree".
* Bug: In cumulus/plugins.chip.powerplanes.Builder._connectHTree(),
there was an inversion of the H & V routing gauges to compute the
track into which put the H-Tree center to corona edge wiring.
This was causing tracks to be used twice, seen in the ao68000 test

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
2014-03-22 05:50:36 -05:00
First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).
2015-02-01 16:24:13 -06:00
Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

2014-03-24 18:59:12 -05:00
Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
This is to ensure better deterministic properties. Between use cases,
additional strings may have to be allocated, shitfing the ids. Even if
hash can be duplicated, we should be able to ensure that the absolute
order in map table should be preserved. Supplemental strings are inserted
in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
block corona corners so the global router do not draw wire under them.
This was creating deadlock for the detailed router.
When the abutment has to be computed, directly use Etesian to do it
instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
standard cells, we trick it by making them bigger during the placement
stage. Furthermore, we do not not uniformely increase the size of the
cells but create a "bloating profile" based on cell size, cell name
or it's density of terminals. Currently only two profiles are defined,
"disabled" which does nothing and "nsxlib" targeted on 4 metal layer
technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
configuration parameter "katabatic.routingGauge" as the default one
may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
contact cache when topology is invalidated. In case of multiple
invalidations, if the first did not invalidate the cache, later one
that may need it where not allowed to do so. The end result was correct
nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
edge capacity, even for the westermost GCell, should be the east
edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
terminal". This is the minimal number of segments separating the
current one from the nearest RoutingPad. This replace the previous
"strong terminal" and "weak terminal" flags.
This distance is used by Katana to sort the events, we route the
segments *from* the RoutingPads *outward*. The idea being that if we
cannot event connect to the RoutingPad, there is no points continuing
as thoses segments are the more constraineds. This gives an order close
to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
dogleg making on those segments. mainly intended for local segments
directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
Now the only case where a segment cannot be reduced is when it is
one horizontal branch in a HTee or a vertical on a VTee. Check if,
when not accounted the source & target VIAs are still connex, if so,
allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
mainly to prevent making doglegs twice on a turn contact. This is to
limit over-fragmentation. If one dogleg doesn't solve the problem,
making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
no turn go be made inside those GCells. Mainly used underneath a block
corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
GCells with too many terminals. Slacken at least one RoutingPad access
when there is more than 8 RoutingPad in the GCell (slacken or change
a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
in non-preferred direction. That is, vertical METAL2 directly connected
to the RoutingPad (then a horizontal METAL2). This alllows for short
dogleg without clutering the METAL3 layer (critical for AMS c35b4).
Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
Perform some other tweaking on METAL1 access topologies, to also
minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
distance to RoutingPad for segments. Set the Unbreakable flag, based
on the distance and segment length (local, short global or long global).
New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
is modificated so net with a degree superior to 10 are sorted first,
whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
in non-preferred routing direction. Mostly intended for small METAL2
vertical directly connected to RoutingPad. Modifications to manage
this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
routed first and whitout the global routing estimation. There should be
few of them so they wont create saturations and we want them as straight
as possible. Detour are for long be-points.
Set the saerch halo to one GCell in the initial routing stage (before
ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
inside NegociateWindow::run(), as segments are inserted into tracks
only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
select whether to replace the perpandiculars *after* or *before* the
current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
segment is fully enclosed inside a global, the longest overlap cost
is set to the shortest global hoverhang (before or after).
When the cost is for a global, set an infinite cost if the overlapping
segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
to any turn connected to the first segment of the RoutingPad so the
perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
RoutingPad, then layer depth. If both distance to RoutingPad is null,
then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
the axis of the segment is not the one of the track (case of wide
segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
is a set of overlaping segments at the "end" of the track, the
EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
segment is at it's ripup limit. We should try *not* to rip it up if
we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
dogleg on source/target (reject if so).

Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.

placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
pointer toward the C++ object to NULL. So when the Python object is
deleted no double-deletion occurs on the C++ object.
Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
choose the right rule for linking the binary wether we use Qt 4 or
Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
that are not placed entirely inside the top cell abutment box (was
causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
contributed by G. Gouvine.
Added EtesianEngine::setDefaultAb() to compute an abutment box if
the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
either Mauka (slow simulated annealing) or Etesian (fast analytic).
New setting 'clockTree.placerEngine' in plugin settings.
2015-02-13 16:38:55 -06:00
Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.
2014-03-22 05:50:36 -05:00
Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).

Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.

Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.

cerr < < Error ( " Unable to lookup instance \" %s \" . " , insName . c_str ( ) ) < < endl ;
First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
without instances. Now it can be software defined with the
"FlattenLeaf" state. If it is flagged "flatten leaf" is will be
considered as a leaf by the trans-hierarchical walkthrough.
This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
locator constructor, the "withLeafCells" argument was forgotten
and was getting the value of "doExtraction" (wich, fortunately,
was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
account or ignore the "FlattenLeaf" flag when doing trans-
hierarchical walkthrough.
Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
the number of instances was under estimated, so the instance array
was oversized and the end went unitialized. So we were getting all
kind of strange behavior from Coloquinte...
Now throw an exception if the number of instances differs from
the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
go through the instance list to remove the potential feed cells.
The netlist is written back after placement *with* the feed
cells added. So, when loading again, they where cluttering the
netlist and giving feed redefintions warning. They also generated
erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
* 1G_1M1_1PinM3
* 1G_xM1_1PinM2
* 2G_xM1_1PinM2
* doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
variable initialized at the first run. So we were getting stuck
with the blockage net of the first cell to be routed. Of course,
it did show only when Katana was run multiple times in the same
process.

pins . push_back ( temporary_pin ( point < int_t > ( xpin , ypin ) , ( * iid ) . second , netId ) ) ;
Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

tracks to avoid are specified by a Box, which should flat and on
the axis of the request track. This feature is used by the H-Tree
to clear the vertical tracks under the tree from any terminal.

* Bug: In cumulus/plugins.block.HTree._connectLeaf(), the TL2 contact,
the one on the *top* auxiliary buffer seemed to have been badly
positioned until now (too low, not using tl2Y).
This is strange because it should have caused disconnections,
but I didn't see it in the wiring and the regressions tests didn't
flag anything wrong. Still a bit weird and worrying.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.

store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine

Implementation of DataBase native save/restore in JSON (step 1).
* New: In Hurricane, added first support for DataBase native import/export
using JSON.
We choose RapidJSON, in SAX mode, to manage the JSON format low level
Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
must be added under ~/coriolis-2.x/src and manually build and installed
in the Coriolis installation tree (to be integrated in ccb later).
Two mode are being supported:
1. Cell mode: one Cell only is saved. In that mode, Entities
referred by Occurrences are "outside" the file. They are coded
through their "signature" (mostly, all the values of their
attributes). The ids saved in the file cannot be restored
identically as we cannot predict when and in which context the
Cell will be reloaded.
2. Design Blob mode: the whole design hierarchy, down and including
the standard cells is saved. This way the design is completly
self contained and Entities ared referred through their ids.
A design blob can only be loaded immediatly after starting cgt
as the DataBase *must* be empty. This way we restore the whole
design hierarchy with *exactly* the same ids.
Now, Hurricane object should provide a "toJson()" method for driving
JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
to allow the hierarchical access of a Cell/Library in native mode
(i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
JSON Design Blobs. Added at this level because we consider it as the
"native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
it's master Cell, we forgot about the Occurrences (through shared pathes).
When an instance is cloned the Shared pathes still points toward the
original Instance. And when it's the master Cell that is uniquifyed
it's the Entities pointed to that remains in the original Cell.
This is a software design problem. It is difficult to define what
policy to adopt when uniquifying: basically that means that one
Occurence is either moved onto the clone or duplicated. Furthermore,
it is not trivial to known what Occurrence is pointing on the
uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
RoutingPads *after* uniquifying (through slaving bounding boxes).
This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
processing the placement so they are put into the right quadtree.
This problem is due to the fact that the RoutingPads do not belong
to the Instance that they refer. And when this instance is moved
around, she doesn't inform the RoutingPad that is has moved.
More software architecture design to review...

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.

* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

unsigned int because we start to need more than 32 different flags
in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
measurements) displaced from Katabatic. This way all ToolEngine
can use this feature. The _postCreate() method display the
memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
builtin timer (remove the local one). Forgot to call the base
class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
Collection allows a deterministic walkthough *all* the AutoSegments
connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
AutoContactTerminal is the *only one* anchored on a RoutingPad,
thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
Created new class DataSymmetric to store symmetric information
of a net (mainly the paired AutoSegments).
Added KatanaEngine::runSymmetricRouter(), for now only build
the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
symmetric information building the non-symmetric routing.

If set NULL (default value) browse through all the instances,
as before.
* Change: In Hurricane::DeepNet, add forgotten Inspector support.
* New: In EtesianEngine, add a "block" (and Instance) attribute to allow
the placement of one specific bloc. If we want to place the core of
a chip and take into account the external terminals (if they are not
already fixed as Pins at the edge of *said* block). We must place
the core *in the context* of it's instanciation in the corona.
Note for G. Gouvine : Pin & external RP should be taken into account
starting at line 629 of EtesianEngine.cpp...
* New: In cumulus/plugins/chip/Chip.py, make use of the new block
placement feature of ETesian.
* Bug: In KatanaEngine::create(), perform a pre-check to prevent trying to
route whole chip, which is forbidden an leads to annoying core-dumps.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.

* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.

* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

Etesian integration with Chip & ClockTree plugins.
* New: In Hurricane, in DebugSession, add a new method to activate the
trace inconditionally with a certain level.
* New: In Hurricane, in HyperNet, allow copy construction as there is
no reason to disallow it and we need it now.
* New: In Hurricane, in Cell::flattenNets(), add a new option to prevent
the flattening of the clock net(s). For more safety perform the
DeepNet creation *outside* the Collection loop.
* Bug: In Hurricane, in Cell_HyperNetRootNetOccurrences, skip the
DeepNets because they are the result of another flattening operation.
* New: In Isobar, in PyBasicLayer, export C++ method getBlockageLayer().
* New: In Isobar, in PyRoutingGauge, export C++ method getLayerPitch(),
needed by Cumulus plugins.
* New: In Etesian, EtesianEngine::findYSpin() to look for the Y orientation
if some cells are already placed. Typically the buffers of a clock
tree.
Pass the correct orienation to row_compatible_orientation().
Do not try to add feeds in the ISPD05 benchmarks. For now the
benchmarks are detected through their names (unreliable).
* Change: In Knik, in KnikEngine::initGlobalRouting(), allow the clock
to be routed as an ordinary signal when the clock tree is not
used.
* New: In Kite, in BuildPowerRails, management & detection for the
pre-routed clock.
In KiteEngine constructor, early initialization of the blockage
net to avoid later troubles in BuildPowerRails.
* New: In Cumulus, in ChipPlugin, add support for Etesian plus new
configuration parameter 'clockTree.placerEngine' to select between
Mauka and Etesian.
* New: In Cumulus, in BlockCorona, add blockages in the vertical sides
in the vertical layer to prevent the router to use the vertical
tracks in under the prower lines (for example, blockage in M3
with power line M5).
In Cumulus, in ChipConf add attribute to access the blockage net.
* New: In Cumulus, when the clock tree is disabled, do not generate
the last rail around the block (the clock rail).
* Bug: In Cumulus, in ChipConf use the clock pad to guess the clock
signals and *not* the power pad.
Add more meaningful error messages if a pad global signal is
not found (implicit connexion by name).
* Bug: In Cumulus, in ClockTree, compute correctly the cells Y spin,
that is *from the bottom of the cell AB* (not from 'zero').

* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
The sub-directory name is 'el7_64'.
In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
display threhold of the layer. This way we can adapt to different
standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
doing it (or not).

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

Implementation of DataBase native save/restore in JSON (step 1).
* New: In Hurricane, added first support for DataBase native import/export
using JSON.
We choose RapidJSON, in SAX mode, to manage the JSON format low level
Read/Write. Thus, it's Git repository http://github.com/miloyip/rapidjson
must be added under ~/coriolis-2.x/src and manually build and installed
in the Coriolis installation tree (to be integrated in ccb later).
Two mode are being supported:
1. Cell mode: one Cell only is saved. In that mode, Entities
referred by Occurrences are "outside" the file. They are coded
through their "signature" (mostly, all the values of their
attributes). The ids saved in the file cannot be restored
identically as we cannot predict when and in which context the
Cell will be reloaded.
2. Design Blob mode: the whole design hierarchy, down and including
the standard cells is saved. This way the design is completly
self contained and Entities ared referred through their ids.
A design blob can only be loaded immediatly after starting cgt
as the DataBase *must* be empty. This way we restore the whole
design hierarchy with *exactly* the same ids.
Now, Hurricane object should provide a "toJson()" method for driving
JSON, and be associated with a JsonObject derived class for parsing.
* New: In Hurricane, ability to force the next id that will be used for a
DBo (used by Design Blob Mode).
* New: In Hurricane, in DataBase, added getCell() and getLibrary() functions
to allow the hierarchical access of a Cell/Library in native mode
(i.e. whithout the requirement of AllianceFramework).
* New: In Hurricane, In CellViewer, added menu entry for Save/Load of
JSON Design Blobs. Added at this level because we consider it as the
"native" format of Hurricane.
* New: In Unicorn, added support of import/export of JSON Cell.
* Bug: In Hurricane, in Instance, when cloning an Instance or uniquifying
it's master Cell, we forgot about the Occurrences (through shared pathes).
When an instance is cloned the Shared pathes still points toward the
original Instance. And when it's the master Cell that is uniquifyed
it's the Entities pointed to that remains in the original Cell.
This is a software design problem. It is difficult to define what
policy to adopt when uniquifying: basically that means that one
Occurence is either moved onto the clone or duplicated. Furthermore,
it is not trivial to known what Occurrence is pointing on the
uniquifyed/cloned item. Have to think about it a little more.
* Bug: In Etesian, in EtesianEngine, build the flattened nets and their
RoutingPads *after* uniquifying (through slaving bounding boxes).
This way we avoid the Occurrences problem described above.
* Bug: In Etesian, in EtesianEngine, invalidate the RoutingPad after
processing the placement so they are put into the right quadtree.
This problem is due to the fact that the RoutingPads do not belong
to the Instance that they refer. And when this instance is moved
around, she doesn't inform the RoutingPad that is has moved.
More software architecture design to review...

// This is temporary as it's not trans-hierarchic: we ignore the positions
Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

// of all the intermediary instances.
Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
until the whole P&R is done, so we potentially can exploit
the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
and ground wires coming from the standard cell, it was assumed
they where made of Horizontal segments, this is not the case
in FlexLib... So force to consider the plane as Horizontal when
we are processing that plane.
Better solution should be to use Horizontals...

First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).

structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine

the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power

Update to Qt 5, requires cmake 2.8.9. New placer: Etesian.
Update to Qt 5:
* Change: Now requires at least cmake 2.8.9.
* Change: CMakeLists.txt needs small changes. Qt modules must be found
one by one (Core, Gui, Widgets). Must add "set(CMAKE_AUTOMOC ON)"
in the top file and replace "qt4" prefix in macros by "qt5".
Added simpler macro "setup_qt()" in FindBootstrap.cmake.
* Change: No longer need to include <QGtkStyle> is is choosen by default
according to the current desktop environment.
* Change: In <hurricane>, In HApplication, launch ExceptionWidget when
a std::exception is catched instead of silently discarting it.
New placer Tool: Etesian
* New: <etesian> analytical placer. Encapsulate Coloquinte from
Gabriel Gouvine.
* New: in <documentation>, add stub demonstration ToolEngine <smurf>.
Needs to be commented.
Miscellaneous:
* New: in <boostrap> and <unicorn>, added support for Etesian, the new
analytic placer. The tool itself will be added in the next commit.
* Bug: in <CellWidget>, when shifting the display buffer, we no longer
can copy the buffer on itself (we should never have). Now go through
a temporary one (PlaneId::AutoCopy) which is added to the
DrawingPlanes. Affect "goLeft()" and "goUp()".
* Bug: In <CellWidget>, remove the WA_PaintOnScreen flag/attribute.
When it's on, no PaintEvent is transmitted to the CellWidget
when it's the central widget of the <CellViewer> (QMainWindow).
It's something I still don't understand from the doc of Qt.
* Change: In <AreaCommand>, use the PlaneId enumeration instead of a
anonymous numerical index.
* Change: In <HApplication>, no longer catch and silently discard
standartd exceptions but launch the ExceptionWidget...
Suppress the now deprecated constructor with "Type" argument.
* Change: In <SelectionModel>, the "reset()" method is deprecated in
Qt5, instead enclose the "clear()" by a "beginResetModel()" and
"endResetModel()" pair.
* New: In <crlcore>, add support for ISPD05 benchmarks (in Bookshelf
format). Forked from ISPD04 and not finished yet.
* Change: In <Mauka>, distinguish the Action string identifier from
<Etesian>
* New: In <unicorn>, add entry for ISPD05 loader. Add entry for
<Etesian> analytic placer.

UpdateSession : : close ( ) ;
First barebone implementation of Etesian. Support for ISPD05 benchmark.
Details:
* New: In <vlsispad/utilities>, new objet Dots for displaying a kind
of progress bar.
* Change: In <vlsisapd/bookshelf>, keywords are now case-insensitive.
Added a "strict syntax" option (to be disabled for ISPD05).
* New: First working implementation of Etesian, at least for ISPD05
"bigblue1".
* Change: In <hurricane>, in Cell::flattenNets(), no longer display
a warning if an instance is unplaced, this does not make sense
when the circuit is not placed.
* New: In <crlcore>, Added translator for ISPD05 bookshelf, the
circuit is *not* placed, unlike in ISPD04 and terminal nodes
*are* true cells.
* New: In <unicorn>, added entry in import cell for ISPD05 benchmarks.

Better handling of exceptions between C++ & Python. Misc. checks.
* Bug: In Hurricane, in PyHurricane.h the macro HCATCH was not catching
standard STL exceptions. This was the source of the cryptic message:
"Fatal Python error: Py_EndInterpreter: thread still has a frame"
The Python interpreter was interrupted uncleanly bypassing it's own
exceptions mechanism.
In PyViewer, the Viewer *do not* inherit from a base class (in the
Python export).
* New: In Hurricane, in DbU, compute maximum values (in double) for
grid, lambda & physical (in meter) so now the DbU::toGrid(),
DbU::toLambda() & DbU::toPhysical() methods can check for out of
bound values, and throw an exception.
* Change: In Hurricane, ExceptionWidget::catchAllWrapper() now returns
a boolean, set to <true> if an exception has been catched. Allow
callers to interrupt themselves if a problem has occured.
* Bug: In Kite & Etesian, in the Python wrapper, send a Python exception
if catchAllwrapper() did return true, instead of continuing...
* Change: In Kite & Etesian, adds a setViewer() method (exported in Python)
to use the graphical ExceptionWidget when in graphic mode.
* Bug: In Cumulus, in PadsCorona.py the check for the core vs. chip size
was not returning False when invalid.
* New: In CRL Core, in Vst driver, add a support IEEE VHDL. Inactive for
now as I don't see clearly the policy for selecting it or not.
Remove the code of the old Vst driver.
In Blif parser, check for non-existent models (incomplete or
corrupted Blif file). Found by G. Gouvine.
* New: Added extras file for IDE-like support under Emacs.

Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
effect management:
* "etesian.diodeName" : the name of the diode cell.
* "etesian.antennaMaxwl" : maximum length above which antenna
effect can occur. Must be the maximum for all the normal
routing layers.
* "etesian.antennaInsertThreshold" : during the placement steps,
threshold for linear disruption at which we will look for
the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
in the placement iteratives step, when the spreading starts to
be significant enough estimate the RSMT length and add a diode
if need be. The diode will be put side by side with the driver
cell. This is done by enlarging the driver cell of the diode
width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
modify the netlist to connect the diode. The diode will be
put on the side of the cell closest to the driver. This may
alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
structure a persistent attribute of the EtesianEngine so
it can be used afterwards.
Add a post-placement diode insertion feature. Finally
unused as they are added on the fly during placement.
In the Area, add data about the diode tie in the TieLut.

Instance * EtesianEngine : : _createDiode ( Cell * owner )
{
if ( not _diodeCell ) return NULL ;
Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).
