* New: In Anabatic::AutoContact and the derived classes, manages wide
wires. The contact self dimension itself according to the segments
it is connected to. Special case for the AutoContactTerminal which
also read the size of the component it is anchored upon.
New refresh method "updateSize()" and flag CntInvalidatedWidth.
to compute the size.
In AutoContactTerminal, compute the constraint box according to
the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
attributes of the class. The flags are stored into a uint64_t as
they are more than 32.
Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
uses the simpler overload of AutoSegment::create() in order to detect
the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
into a one-track method and a segment level method that iterate over
the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
to a specific track. So the base functions have now two parameters:
"icost" and "itrack" (has a cost can have multiple tracks in the case
of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
it's track, as for a wide segment it will not be meaningful for the
non-base track. This means that we have to use the Track::find()
method each time instead.
Remove the wide flag, as it is a duplicate of the one in AutoSegment.
Added a getTrackCount() method to tell the number of track the
segment is inserted into. Needed in the Track destroy step to delete
a segment only when the last track that refers it is destroyed.
Added getSymmetricAxis() to correct the computation of the symmetric
base track in case of wide segment as the base track is not centered
but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
track span.
* Change: In TrackSegment::create(), now activate the factory and create
wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
problem (ever shifting to the right).
* 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 Anabatic::GCell, new functions getConstraintUMax() to return the
correct bounding box for the last north/east GCell. The GCells do not
own their north/east edges, except for the last ones. Thoses functions
must distinct from getUMax() because for them, the shrink is always
applied. getConstraintBox() uses the "getConstraintUMax()" functions.
* Bug: In Anabatic::AutoContact, initialize the constraint box from the
new GCell::getConstraintUMax(), to manage correctly the boundaries
of the nothernmost & easternmost GCells. The problem was showing for
pins on the north/east side of a circuit, the constraint
* Bug: In Anabatic::AutoContactHTee, Anabatic::AutoContactVTee and
Anabatic::AutoContactTerminal forgot to call the _preCreate() function
in the various create().
* Bug: In Matrix::getUnder(), if on the N/E boundary, decrease by one to
be enclosed in it.
