- Change: Propagate renaming "obstacle" -> "blockage".
- Bug/Change: In Configuration, the value of the extensionCap was too big
(1.5 lambda), reduce to 0.5 lambda. This is a problem, the extension
should be coupled to the layer as it is not the same for each METAL.
- Bug: When using TrackElement, always uses the virtual "->isFixed()" method
instead of trying to access to "->base()->isFixed()" as the base may be
NULL in case of blockage/fixed segment.
- Change: Merge PowerRails & Blockage trans-hierarchical construction (into
PowerRails). All blockages are groupeds under "blockagenet".
Allows to remove TrackBlockage & BuildBlockages.
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
ring power segments around the core must completly saturate the edges
in their segment direction. This is to prevent the global router to
use paths under the power/ground ring (may generate unsolvable configs).
- Change: In KiteEngine::annotateGloblalGraph(), when routing a full chip,
distinguish three areas: the core (65%), the corona (90%) and the pads
(100%). Capacities on the edges are sets accordingly.
- Change: In RoutingEvent, introduce an alternative algorithm for
conflictSolve1, FindPath which try to deduce the breakpoints from a
truly explorated path. Unfortunatly this gives worst results than the
Cs1Candidates method. The why should be investigated as it's a critical
point in the algorithm.
- Change: In Manipulator::ripupPerpandicular(), when a caged perpandicular
is encountered, instead of just "stopping", rip it up and change is
axis hint (actually increase) it's axis hint so it stands a chance to
go outside the track with an obstacle.
- Change: In RoutingEvent/State::slackenTopology(), allow move up of local
segments when they are tightly constrained *and* blocked (cageds).
Partial modification of functions calls from booleans to flags.
- Bug: In NegociateWindow::NegociateOverlapCost, check for fixed segments
before trying to get DataNegociate. The lack of DataNegociate cause the
TrackElement to be discarted. It's a failsafe behavior, but it leads to
overlaps.
- Bug: In ProtectRoutingPad, in Pad Cells only, *do not* protect RoutingPad
to avoid the edge capacity over the pad to decrease to zero. This is
due to unused RoutingPads being accounted as blockages.
