* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.
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.
* New: In CRL/etc/symbolic/phenitec06, configuration for symbolic
layout targeted for Phenitec 0.6um (do not contains any NDA
covered informations). Could be used for any 3 metal layers
techno.
* Bug: In Cumulus/plugins/chip/Configuaration.py, _setStackposition()
disable stack error when there is no slave component on the stack
(happens when the stack consists only of one contact).
