Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Support for density estimation for the global router.
* Bug: In Anabatic::Edge::getDistance(), remove the additionnal 0.1
added to horizontal edges. This was for testing before the hScaling
parameter was added (to the distance computation in GlobalRoute).
* New: Anabatic::Path_Edges, collectio to walkthrough all the edges
between two node. More complex than in Knik as we are no longer
using a regular grid. We may request the north bound path or south
bound path.
Collection returned by AnabaticEngine::getEdgesUnderPath().
* New: In Anabatic::NetData, add a new flag GlobalEstimated to tell if
the net RMST has been computed (using FLUTE).
* New: In Anabatic::PriorityQueue, used to sort Vertexes by increasing
distances, add a new criterion to be used in case of distance
equality. The attractor which should be the center of the search
area. In case of equality, we choose the Vertex which is closest
to the attractor. Give a small improvement, and more "dendritic"
trees.
For a more simple implementation of the comparison function it is
made as a static member (so no two Dijkstra objects at the same
time...).
* Change: In Anabatic::Edge, make the estimate occupance a floating
point number instead of an integer.
* New: In Katana::GlobalRoute, finally implement the estimated congestion
driven router. Net RMST estimated using FLUTE.
Use the historic cost from Knik implementation and not the one
given in Damien's thesis, which seems not be the same and a bit
strange.
* New: In KatanaEngine, add the ability to exclude nets from routing,
and export it to Python.

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 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...

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Synchronize priority of TrackSegments connecteds through doglegs.
* Bug: In Anabatic::Dijsktra, correct the indentation in cdebug calls
(lots of them causing a big shift right).
* New: In Anabatic::TrackSegment, new helper structure SideStack to
manage a set of aligned GCells and their various sides sizes.
* Change: In Anabatic::TrackSegment::computeOptimal(), more accurate
computation of attractors from global segments and variable size
GCells using SideStack.
* Change: In Katana::DataSymmetric::checkPairing(), increase the tolerance
for misaligned symmetrics from 2 to 5 tracks (should be enough for our
narrow channel routing).
* New: In Katana::TrackSegment, add a first flag to enable locking of
priority. If it is set, calls to either "computePriority()" or
"forcePriority()" will have no effect. Added the uint32_t flags
paraphernalia.
* New: In ::computeNetPriority(), overall function to control the call
of TrackSegment::computeAlignedPriority(). The call is done from
NegociateWindow::run().
* New: Katana::TrackSegment::computeAlignedPriority(), order the
TrackSegments aligneds through doglegs to the one with the highest
priority is routed first and others progressively from him. Done by
forcing an ever decreasing priority on the aligneds ones.
The amount of decrease is small so the aligned segments got routed
(ordered) in close, if not contiguous, sequence. Priority is locked
for the order to remain.
* Bug: In Katana::TrackSegment::computePriority(), correct computation
of the priority when there is more than 10 free tracks
(a DbU::toLambda() call was missing, leading to very big priorities).
* Change: In katana::TrackCost CTOR, do not compute a distance to fixed
in the case of analog segments, this is backfiring.
Slight change of the compare function when delta differs. Seems
to improve a little.

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.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
limit. The two limits are checked only when a new Entity object is
created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
parameter to specify the name of the ground/power signals to be
created if they are missing in a Cell. For Alliance libraries it
would be "vss" & "vdd" (default values), but for real technologies,
it is often "gnd!" & "vdd!".
The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
the center of the GCells common side. Gcells under a segment are
found by using the edge that cover the segment axis. When we have
a "bend" GCell stack and the axis is wrong, they could be ommited.
This was causing deleted segments to be not removed from some
Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
reference contact, select the fixed or terminal one instead of
always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
segment going through an Edge is starting/ending in either source
or target GCell of the edge (active only when running in channel
mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
only if it is not ending in either source or target (channel mode
only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
segment which is ending in either source or target (we *have* to
access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
the Edge which is on the side that will get splitted by the cut.
It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
update horizontals or verticals only. We may require only a partial
update when resizing the GCell in only one direction.
This, again, related to the fact that we compute the GCells under
a segment thanks to it's axis position, so we need to be very careful
when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
Edges can have a zero capacity, but still be reachable if the net has
a terminal in either source or target. Look for this case and return
a distance of zero instead of "unreachable". This was causing the
global routing not to complete in channel mode.
For computing the edge distance, makes the vertical edges much more
long (10 times) than the horizontal ones as the vertical capacity is
very limited. Hard coded for now, should make it a parameter in the
future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
of edges with reserveCapacity for each terminal inside a GCell.
Both north and south edges are decreased as we a terminal will
block both north and south edges.
As a counterpart, the Edge capacity is not decreased when the
global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
do not expand the slack for horizontal segments in channel mode.
So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
layout.

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...

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Improved handling of short nets (fully included in one GCell).
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.
* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
output of zero and one cell, also skip the blockage net (as well as
automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
segment is part of a short net (fully included in *one* GCell).
Also add accessor/mutators for the _analogMode flag (was it ever
used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
"short net" and "analog mode" creation flags between two different
nets.
* New: In Katana::Configuration, added dedicated ripup for short net
segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
is dogleg that are always kept in same metal because they connect
neighboring perpandicular tracks. Not finished neither activated
yet.
* New: In Katana::TreckElement and derived, export the the *short net*
support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
successfully inserted, re-process any perpandicular that is in
repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
of issuing false check messages.

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.

Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
limit. The two limits are checked only when a new Entity object is
created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
parameter to specify the name of the ground/power signals to be
created if they are missing in a Cell. For Alliance libraries it
would be "vss" & "vdd" (default values), but for real technologies,
it is often "gnd!" & "vdd!".
The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
the center of the GCells common side. Gcells under a segment are
found by using the edge that cover the segment axis. When we have
a "bend" GCell stack and the axis is wrong, they could be ommited.
This was causing deleted segments to be not removed from some
Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
reference contact, select the fixed or terminal one instead of
always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
segment going through an Edge is starting/ending in either source
or target GCell of the edge (active only when running in channel
mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
only if it is not ending in either source or target (channel mode
only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
segment which is ending in either source or target (we *have* to
access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
the Edge which is on the side that will get splitted by the cut.
It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
update horizontals or verticals only. We may require only a partial
update when resizing the GCell in only one direction.
This, again, related to the fact that we compute the GCells under
a segment thanks to it's axis position, so we need to be very careful
when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
Edges can have a zero capacity, but still be reachable if the net has
a terminal in either source or target. Look for this case and return
a distance of zero instead of "unreachable". This was causing the
global routing not to complete in channel mode.
For computing the edge distance, makes the vertical edges much more
long (10 times) than the horizontal ones as the vertical capacity is
very limited. Hard coded for now, should make it a parameter in the
future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
of edges with reserveCapacity for each terminal inside a GCell.
Both north and south edges are decreased as we a terminal will
block both north and south edges.
As a counterpart, the Edge capacity is not decreased when the
global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
do not expand the slack for horizontal segments in channel mode.
So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
layout.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so

* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).

transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not

"Katana" for Kite-Analogic. When it's capabilities and performances

back the "Kite" name). Preliminary tests seems to show that, contrary

Support for density estimation for the global router.
* Bug: In Anabatic::Edge::getDistance(), remove the additionnal 0.1
added to horizontal edges. This was for testing before the hScaling
parameter was added (to the distance computation in GlobalRoute).
* New: Anabatic::Path_Edges, collectio to walkthrough all the edges
between two node. More complex than in Knik as we are no longer
using a regular grid. We may request the north bound path or south
bound path.
Collection returned by AnabaticEngine::getEdgesUnderPath().
* New: In Anabatic::NetData, add a new flag GlobalEstimated to tell if
the net RMST has been computed (using FLUTE).
* New: In Anabatic::PriorityQueue, used to sort Vertexes by increasing
distances, add a new criterion to be used in case of distance
equality. The attractor which should be the center of the search
area. In case of equality, we choose the Vertex which is closest
to the attractor. Give a small improvement, and more "dendritic"
trees.
For a more simple implementation of the comparison function it is
made as a static member (so no two Dijkstra objects at the same
time...).
* Change: In Anabatic::Edge, make the estimate occupance a floating
point number instead of an integer.
* New: In Katana::GlobalRoute, finally implement the estimated congestion
driven router. Net RMST estimated using FLUTE.
Use the historic cost from Knik implementation and not the one
given in Damien's thesis, which seems not be the same and a bit
strange.
* New: In KatanaEngine, add the ability to exclude nets from routing,
and export it to Python.

not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
flag) "LongLocal". Analog GCells can be very wide, so at least some
carefuly choosen long local segments must be took into account as
attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
RoutingPads using layer masks instead of Layer pointers. Allows to
find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
and _doDevice(), tag long locals as "LongLocal". This need to be
reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
analogic GCells the _optimalMin & _optimalMax bitfields must use
16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
where too short for the Analog GCell size, now uses 16 bits instead of
6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
GCell if *both* width and height are under 150 pixels.
* New: In Katana::Session, add a new isOpen() method.

- isAnalogMode()
- isMixedMode()
- isChannelMode()

- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform

Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
to allow different behavior between digital and analog modes.
For "Aligneds" and "Perpandiculars" collections, now manage a new
Flag WithDoglegs to follow aligned globals through local doglegs
(for analog nets).
Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
part of an analog net.
Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
objects and *not* uint64_t. This avoids overload resolution problems with
arithmetical overload of the operators.
The BaseFlags/Flags types are now completly "isolated" from the
uint64_t, it has the advantage of showing where unwanted previous implicit
conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
to allow to substract the topmost and rightmost track for axis span
computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent

modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
flag) "LongLocal". Analog GCells can be very wide, so at least some
carefuly choosen long local segments must be took into account as
attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
RoutingPads using layer masks instead of Layer pointers. Allows to
find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
and _doDevice(), tag long locals as "LongLocal". This need to be
reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
analogic GCells the _optimalMin & _optimalMax bitfields must use
16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
where too short for the Analog GCell size, now uses 16 bits instead of
6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
GCell if *both* width and height are under 150 pixels.
* New: In Katana::Session, add a new isOpen() method.

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
flag) "LongLocal". Analog GCells can be very wide, so at least some
carefuly choosen long local segments must be took into account as
attractors in the computation of the optimal axis.

analogic GCells the _optimalMin & _optimalMax bitfields must use

* New: In Katana, reorganisation of the initialization procedure to fit

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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...

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

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).

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.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of
Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
so RoutingPad will be build upon in global routing.
Do not complain when a I/O pad has a physical instance that did
not exists in the netlist. Just create it (appeared in phlib80).
When no netlist instance exists in a pad, the pad Cell is still
considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
target points instead of a segment. Needed to manage wide segment for
which the axis to consider is not that of the segment (one axis for
each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
all edges of a fixed amount (hTrackReservedLocal), guess the GCell
cluttering from the number of RoutingPads that it contains.
For non-saturated GCells, the four edges are decreased by the number
of RoutingPads. We use the maximum from the two neigboring GCells.
The hTrackReservedLocal parameter is now used only as a *maximum*
that the edge reservation can reach.
If a GCell is saturated (more than 8 RoutingPads, the saturation is
propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
flexible gauge name matching for terminal vertical extensions correction.
Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
position, even if it is a non-canonical segment. Maybe needed in the
initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
to manage coronas for Phenitec designs.
To avoid various side effects from segments being too close from
the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
wires was wrong. The axis to use to find the underlying GCells is the
one of the track, not of the segment. This was creating bad edge
capacity computation under the power ring of a block and subsequently
routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
METAL2 in non-preferred direction, restrict the terminal and turn
constraint box at the current position of the perpandicular, so it
doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
parameters:
katana.termSatReservedlocal
katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
limit. The two limits are checked only when a new Entity object is
created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
parameter to specify the name of the ground/power signals to be
created if they are missing in a Cell. For Alliance libraries it
would be "vss" & "vdd" (default values), but for real technologies,
it is often "gnd!" & "vdd!".
The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
the center of the GCells common side. Gcells under a segment are
found by using the edge that cover the segment axis. When we have
a "bend" GCell stack and the axis is wrong, they could be ommited.
This was causing deleted segments to be not removed from some
Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
reference contact, select the fixed or terminal one instead of
always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
segment going through an Edge is starting/ending in either source
or target GCell of the edge (active only when running in channel
mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
only if it is not ending in either source or target (channel mode
only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
segment which is ending in either source or target (we *have* to
access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
the Edge which is on the side that will get splitted by the cut.
It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
update horizontals or verticals only. We may require only a partial
update when resizing the GCell in only one direction.
This, again, related to the fact that we compute the GCells under
a segment thanks to it's axis position, so we need to be very careful
when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
Edges can have a zero capacity, but still be reachable if the net has
a terminal in either source or target. Look for this case and return
a distance of zero instead of "unreachable". This was causing the
global routing not to complete in channel mode.
For computing the edge distance, makes the vertical edges much more
long (10 times) than the horizontal ones as the vertical capacity is
very limited. Hard coded for now, should make it a parameter in the
future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
of edges with reserveCapacity for each terminal inside a GCell.
Both north and south edges are decreased as we a terminal will
block both north and south edges.
As a counterpart, the Edge capacity is not decreased when the
global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
do not expand the slack for horizontal segments in channel mode.
So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
layout.

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of
Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
so RoutingPad will be build upon in global routing.
Do not complain when a I/O pad has a physical instance that did
not exists in the netlist. Just create it (appeared in phlib80).
When no netlist instance exists in a pad, the pad Cell is still
considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
target points instead of a segment. Needed to manage wide segment for
which the axis to consider is not that of the segment (one axis for
each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
all edges of a fixed amount (hTrackReservedLocal), guess the GCell
cluttering from the number of RoutingPads that it contains.
For non-saturated GCells, the four edges are decreased by the number
of RoutingPads. We use the maximum from the two neigboring GCells.
The hTrackReservedLocal parameter is now used only as a *maximum*
that the edge reservation can reach.
If a GCell is saturated (more than 8 RoutingPads, the saturation is
propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
flexible gauge name matching for terminal vertical extensions correction.
Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
position, even if it is a non-canonical segment. Maybe needed in the
initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
to manage coronas for Phenitec designs.
To avoid various side effects from segments being too close from
the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
wires was wrong. The axis to use to find the underlying GCells is the
one of the track, not of the segment. This was creating bad edge
capacity computation under the power ring of a block and subsequently
routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
METAL2 in non-preferred direction, restrict the terminal and turn
constraint box at the current position of the perpandicular, so it
doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
parameters:
katana.termSatReservedlocal
katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.

initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
to manage coronas for Phenitec designs.
To avoid various side effects from segments being too close from
the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
wires was wrong. The axis to use to find the underlying GCells is the
one of the track, not of the segment. This was creating bad edge
capacity computation under the power ring of a block and subsequently
routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
METAL2 in non-preferred direction, restrict the terminal and turn
constraint box at the current position of the perpandicular, so it
doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
parameters:
katana.termSatReservedlocal
katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.

Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of
Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
so RoutingPad will be build upon in global routing.
Do not complain when a I/O pad has a physical instance that did
not exists in the netlist. Just create it (appeared in phlib80).
When no netlist instance exists in a pad, the pad Cell is still
considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
target points instead of a segment. Needed to manage wide segment for
which the axis to consider is not that of the segment (one axis for
each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
all edges of a fixed amount (hTrackReservedLocal), guess the GCell
cluttering from the number of RoutingPads that it contains.
For non-saturated GCells, the four edges are decreased by the number
of RoutingPads. We use the maximum from the two neigboring GCells.
The hTrackReservedLocal parameter is now used only as a *maximum*
that the edge reservation can reach.
If a GCell is saturated (more than 8 RoutingPads, the saturation is
propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
flexible gauge name matching for terminal vertical extensions correction.
Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
position, even if it is a non-canonical segment. Maybe needed in the
initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),

Added direct management of macro blocks I/O pins in METAL2 & METAL3.
The decoupling of the cell gauge and the routing gauge implies that
the METAL2 & METAL3 terminals of macro blocks cannot be aligned on
the routing tracks anymore. That is, an horizontal METAL2 terminal
will not be on a track axis, but offgrid, so we no longer can use
a METAL2 horizontal segment to connect to it. Making an adjustement
between the offgrid terminal and the on-grid segment has proven
too complex and generating difficult configuration for the router.
Moreover, METLA2 terminal could be fully inside a METAL2 blockage.
So now, when the gauges are decoupled, we connect the METAL2 and
METAL3 the same way we do for METAL1: *from above* in the perpandicular
direction and using a *sliding* VIA. We assume that those kind of
terminals in upper metals are quite long.
* New: In Hurricane::Rectilinear, export the isNonRectangle() method
to the Python interface.
* New: In CRL::RoutingGauge, add function isSuperPitched() with the
associated boolean attribute. Set to true when each pitch of
each layer is independant (not low fractional multiples).
* New: In AnabaticEngine, add the ability to temporarily disable the
canonize() operation (mainly used in dogleg creation).
* New: In AutoSegment::canonize(), do nothing if the operation is
disabled by AnabaticEngine.
* Bug: In Session::_revalidateTopology(), disable the canonization
during the topology updating of a net. Too early canonization
was occuring in makeDogleg() leading to incoherencies when
performing the later canonization stage over the complete net.
Mostly occured in the initial build stage of the net.
* New: In GCell, add function postGlobalAnnotate(), if a layer
is fully blocked (above 0.9), typically, under a blockage,
add a further capacity decrease of 2 on the edges. So we may
handle a modicum of doglegs.
* Bug; In GCell::addBlockage(), removeContact(), removeHSegment()
and removeVSegment(), forgot to set the Invalidated flag.
This may have lead to innacurate densities.
* Change: In GCell::updateDensity(), more complex setting of the
GoStraight flag. This flag is now set if we don't have two
*contiguous* below 60% of density. We need free contiguous
layers to make doglegs.
* New: In NetBuilder, now manage a current state flag along
with the state flag of the *source* GCell. This flag is used
to tell if the GCell needs it's *global* routing to be done
using the upper layers (METAL4 & METAL5) instead of the
lower ones.
* New: In NetBuilder::setStartHook(), set the state flag of the
GCell to ToUpperRouting when processing a global routing
articulation and one of the base layer is obstructed
above 0.9.
In GCell with terminals, also set ToUpperRouting when there
are some in METAL2 / METAL3 and the gauge is not super-pitched.
* New: In NetBuilder, function isInsideBlockage(), to check if a
terminal is completely or partially enclosed in a blockage.
* Change: In NetBuilderHV::doRp_AutoContact(), remove support for
trying to put on grid misaligned METAL2/METAL3.
Instead systematically access them from above.
Do not cover with fixed protection terminals that are already
enclosed in blockages.
* Bug: In NetBuilderHV::doRp_AutoContact(), always add the terminal
contact in the requested GCell and not the target/source one,
in case the terminal span several GCells.
* Change: In NetBuilderHV::doRp_Access(), create the local wiring
according to the RoutingPad layer.
* Change: In NetBuilderHV::_do_xG(), _do_2G(),
create the global wiring in upper layers, according to the
ToUpperRouting flag.
* Change: In NetBuilderHV::_do_xG_xM3(), now delegate to
_do_xG_xM3_baseRouting() and _do_xG_xM3_upperRouting() if the
density at terminal level is above 0.5.
* New: NetBuilderHV::_do_xG_xM3_baseRouting() and
_do_xG_xM3_upperRouting() separated function to manage the
local routing.
* Change: In NetBuilder::_do_globalSegment(), if the currently
processed GCell or it's source is in ToUpperRouting mode,
move up the global segment. Do *not* use the moveUp() function
which would create doglegs unwanted at this stage.
* New: In KatanaEngine::annotateGlobalGraph(), call postGlobalAnnotate()
on the GCell after the blockages have been taken into accound to
add the penalty.
* Bug: In Track::getPrevious(), correctly manage the 0 value for the
index argument. Strange it didn't show earlier.
Same goes for Track::expandFreeInterval().

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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.

Synchronize priority of TrackSegments connecteds through doglegs.
* Bug: In Anabatic::Dijsktra, correct the indentation in cdebug calls
(lots of them causing a big shift right).
* New: In Anabatic::TrackSegment, new helper structure SideStack to
manage a set of aligned GCells and their various sides sizes.
* Change: In Anabatic::TrackSegment::computeOptimal(), more accurate
computation of attractors from global segments and variable size
GCells using SideStack.
* Change: In Katana::DataSymmetric::checkPairing(), increase the tolerance
for misaligned symmetrics from 2 to 5 tracks (should be enough for our
narrow channel routing).
* New: In Katana::TrackSegment, add a first flag to enable locking of
priority. If it is set, calls to either "computePriority()" or
"forcePriority()" will have no effect. Added the uint32_t flags
paraphernalia.
* New: In ::computeNetPriority(), overall function to control the call
of TrackSegment::computeAlignedPriority(). The call is done from
NegociateWindow::run().
* New: Katana::TrackSegment::computeAlignedPriority(), order the
TrackSegments aligneds through doglegs to the one with the highest
priority is routed first and others progressively from him. Done by
forcing an ever decreasing priority on the aligneds ones.
The amount of decrease is small so the aligned segments got routed
(ordered) in close, if not contiguous, sequence. Priority is locked
for the order to remain.
* Bug: In Katana::TrackSegment::computePriority(), correct computation
of the priority when there is more than 10 free tracks
(a DbU::toLambda() call was missing, leading to very big priorities).
* Change: In katana::TrackCost CTOR, do not compute a distance to fixed
in the case of analog segments, this is backfiring.
Slight change of the compare function when delta differs. Seems
to improve a little.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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.

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

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.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot

It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not

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.

Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
workaround for a Hurricane problems. When an instance is moved, the
RoutingPads that use it must be moved accordingly, but they are not
invalidated so they stay in the wrong QuadTree.
New method ::_resizeMatrix() to be called when the associated Cell
is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
now return a boolean to tell if it was ok (must not encounter a NULL
GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
- getDHorizontalLayer()
- getDhorizontalDepth()
- getDHorizontalWidth()
- getDHorizontalPitch()
And so on for Vertical and Contact.
They supply depth-independant informations about the H/V layers to
build the initial detailed routing.
The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
for implementing 2-Metal blocks.
Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
move the contents of GCell::updateContactsPosition() into it and
suppress it.
WARNING: In case of a GCell shrink this may cause problems. But for
now we only expand...
New method GCell::getNetCount() to count the number of Net going
though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
calls by "not gcell->isAnalog()". Add more check so that the methods
pertaining to the analog routing (GRData) are not called in digital
mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
cases. That is, always break in case of vertical pass-through or
U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
to ensure the revalidation. The "::revalidate()" method is then moved
as "::materialize()" (overload of Go) and "::_invalidate()" becomes
"::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
* ForkStack is now an object attribute as many methods do need it.
* To push segments/hook on the stack, a new method "push()" is
available. Perform NULL and fromHook checking. Can also setup
_southWestContact or _northEastContact if it is the "from" edge.
* N/S/E/W edges are now vector as in digital channel mode there
can be more than one.
* Added build topological build methods:
- doRp_2m_Access() RoutingPad stem access.
- _do_2m_1G_1M1() North or south access.
- _do_2m_2G_1M1() North AND south access.
- _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
for channel routing, calls to setupPowerRails() and
protectRoutingPads() must be called after the core block has
been fully dimensionned.
::runGlobalrouter() contains the code tasked with the grid creation
and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
May be expanded for over-the-cell routing in the future.
Added methods :
- isDigitalMode()
- isAnalogMode()
- isMixedMode()
- isChannelMode()
- getBlock() / addBlock()
- setupChannelMode()
- createChannel()
* New: In Katana, new class Block to manage core blocks and perform
channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

* 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.
