* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
when the anchor is a RoutingPad (which must be always the case),
perform the true computation of it's position based on the
segment occurrence. It is a important change, previously the
area was in fact the "center line" of the connector while now
it is really an area (mandatory for "half-offgrid" terminals of
real technologies).
The change is not complete yet, the area should be shrinked
by the half size of a VIA, because the area applies to the center
coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
is created (restore connexity after a layer change) the layer of
the VIA, based on the segments it connects to must be re-computed
*after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
use the Layer pointer itself, but the layer mask. This allow a
transparent management of both real and symbolic layers (which
do share the same mask). Real metal layers (not VIAs) will be
BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
RoutingPad component for metal1 terminals. Look for the metal1
component with the biggest accessibility on-grid.
RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
neighbor Vertex through an Edge*. This method allows to write
clearer code as we no longer need to access the neighbor through
the underlying GCell.
Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
a component with multiples vertexes is reached *and* two of it's
vertexes are reached *at the same time* (one from which we backtrack
and one still in the queue) extraneous edges may be created by
_materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
To solve this, Dijkstra::_toSource() is modificated, the "from"
edges of the newly reacheds vertexes are reset to NULL, *except*
for the one we will be backtracking from. That is, the one given
in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
This unset flag was causing AutoContactTurn::updateTopology()
to not work as expected and making gaps, this was the cause of
the last remaining warnings about layer connexity.
* New: In Anabatic::NetBuilder, set all the attributes as private and
create accessors and mutators.
Finish virtualising all GCell build methods and transfer them
into the NetBuilderHV class.
Build methods now return a boolean to tell if the GCell was
processed or not, to allow cascading in the "big switch".
Reorganise the "big switch" in separate sections only partially
cascading.
Truly fuse the *big switch* for channel routing and over-the-cells.
Create a new method "_do_globalSegment()" to delagate the
drawing of global segments between two GCell to the derived classes.
