* New: In Hurricane, dedicated class BaseFlags to wrap a set of flags.
Similar to the Mask class, only with a slightly different semantic.
Encapsulation of <unsigned int>.
Also provide support for the Inspector, to have a human-readable
display of the flags.
* Change: In Hurricane, in Cell, regroup all the flags under a Flags
sub-class of Cell. No more mixing between booleans and bit flags.
(first use of BaseClass).
* In Hurricane, CRL Core & Knik, many small corrections to suppress
annoying warning messages at compile time.
Most noticeably, Bison errors in VstParserGrammar generated by
rules and token with mismatched return value type. This was not
problematic because the badly defined return value where not used.
But still...
* New: In Hurricane, in Collection add simple STL iterator support.
So now the C++11 "for" instruction can be used instead of the
in-house "forEach".
Example:
forEach ( Component*, icomponent, net->getComponents() ) {
cout << (*icomponent) << endl;
}
Become:
for ( Component icomponent : net->getComponents() ) {
cout << icomponent << endl;
}
* New: In Kite, in BuildPowerRails more accurate GCell density computation
under the pad area, to limit the overloaded messages.
* New: In Cumulus, In BlockCorona, remove the vertical METAL3 blockages
and replace them by horizontal blockages completly enclosing the
corona big vias in all layers. This way the I/O wires that goes
through the corona are guided to be straight and do not creates
unsolvable doglegs due to the presence of big vias.
* Change: In Kite & Etesian, small typo: refactor the method
"::wipeOutRouting()" into "::wipeoutRouting()" (indulge me, I'm a
code maniac).
* 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.
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
iterate over all the aliases names (this *not* include the main
net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
uniquification (update documentation).
All Cells that are uniquified from a given model are kept in an
Uniquify relation. This relation allows to get all the clones and
generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
a partially loaded Cell in case of parser failure, let the incomplete
Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
statistics.
* New: In Hurricane, In Cell, add Placed and Routed flags to know the
state of the Cell.
* Change: In CRL Core, In ApDriver, do not save the RoutingPads as
external connectors if the design is *not* routed (create
conflics on reload with the newly generated RoutingPads).
* Change: In Etesian, set the Placed flag on the Cell.
* Change: In Kite, set the Routed flag on the Cell.
* Change: In Cumulus, in RSavePluginAll, save the layout only if it
has a bounding box.
* Change: In Bootstrap & ccb, the coloquinte project is renamed into
"importeds", it will be the home of all the externally
devellopped softwares that are needed to build Coriolis.
Add explicit support for Fedora ("Linux.fc") and uses
site-packages, as everybody else.
* New: In CRL Core, in etc/, adds the configuration files for Etesian.
* New: In Etesian, activate the Configuration object. Now uses it's
own configuration variables instead of borrowing those of
Nimbus & Mauka.
* Change: In Documentation, updated User's Guide to present Etesian
as the placer, instead of Mauka.
* Change: In Cumulus, slight change in ClokTreePlugin and ChipPlugin
to match the new Etesian/Python interface.
* 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...
* New: In Stratus1, add a buildModel() utility function to automate
the model generation and allow a call by the model name (string).
* Change: In Unicorn, in cgt.py, display the Alliance environement.
* 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').
* 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.
* 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).
* New: In Bootstrap, added support for RHEL7 in ccb.py & coriolisEnv.py.
In coriolisEnv.py, under RHEL6, directly launch a shell under
devtoolset-2 (do not put it in .bashrc).
* Change: All tools, compliance with Clang 3.2.
- Call using namespace std *after* at least one include of std has
been used.
- In Utilities.h define both const and non-cont overload for operator<<
of mstream (this was the true cause of the Banner display problem).
- No longer use defaults arguments in templates, instead create two
separated overloads.
- Put template static attributes allocation outside of namespaces
(this one I'm not sure how to justify).
- Protect by NDEBUG variables that are only needed in assert().
- In PyInterval getUnion() & getIntersection() we where silently
overwriting the "self" object (interval).
- In Mauka, *do no* overload _postCreate() and add an argument, breaks
the virtual function mechanism. Rename it into _maukaPostCreate().
Idem for SubRow().
- In Katabatic::GCell(), invalidate() overload a Go funtion but is
used for different purpose at this level. Rename it invalidateCt()
(invalidate *ConTents*).
- Miscellaneous small cleanup.
* Change: In bootstrap, in ccb, builder and coriolisEnv.py, correct detection
of the windows architecture (32 or 64 bits). Under Cygwin, add the
directory of the dll into the PATH also. Uses "site-package" as the
location of Python modules (*not* "dist-package").
Use gnu++0x under Cygwin instead of c++11.
* Change: In Etesian, if Coloquinte is not found, do not stop the compilation,
just disable the tool altogether.
* Change: In Hurricane, In Backtrace, disable backtrace under Cygwin as it
uses features specific of the glibc.
* Change: In Knik, use HUGE_VAL instead of HUGE (not present under Cygwin),
add the <cmath> header.
* Change: In Unicorn, Coloquinte no longer stops the compilation.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.
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:
* 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.
