* 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).
* New: In Katana::TrackCost, the TrackElement and it's optional
symmetric are now kept as attribute of a TrackCost. The cost
is completly computed inside the constructor.
TrackCost now support any mix of symmetric event and wide
segments.
The cost is now computed by adding directly to the current
one instead of creating secondaries that are merged afterwards.
As a consequence, remove all copy construction and merge
capabilities.
All the various methods used to compute the cost are renamed
"addOverlapcost()" in all the various related objects.
As a reminder, the overal cost method call is as follow:
1. TrackCost constructor on a TrackElement.
2. Call TrackElement::addOverlapcost()
3. For all Track under the TrackElement, call
Track::addOverlapCost()
4. For all other TrackElement intersecting with
the overlap interval call:
TrackElement::incOverlapCost()
5. The callback overlap function for segments
is called (defined in NegociateWidow).
Don't confuse:
- TrackElement::addOverlapCost(), which compute the cost of
inserting the segment inside a track (or a set of).
- TrackElement::incOverlapCost(), which compute the cost of
overlaping with this already inserted segment. It is the
other way around of the previous one.
* Change: In Katana::SegmentFsm, use a vector of pointer to TrackCost
instead of an object to avoid copy construction.
