- 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.
- New: In Configuration & RoutingEvent, adds support for minimal break length
by layer (METAL1 through METAL7).
- New: Added measures for final detailed wirelength, wirelength expansion ratio,
failed wirelength, number of processeds events and number of unique events.
- Change: In TrackCost, the ripup cost is now computed from a mix between
the number of ripup *and* the data state. Restore a correct balance
of the ripping up between segments.
- New: In RoutingEvent::State::conflictSolve1(), when a very long Segment
enters in conflictSolve1(), still prefers to move it up in one piece,
but if it's not possible, it is unlikely that it will overlap with
only one or two other Segment. In that cases, blindy break it up in
the middle.
- New: In RoutingEvent::Manipulator, another overload of makeDogLeg to
allow break up at one precise point.
- Change/Bug: In RoutingEvent::Manipulator::Relax(), reset the state of
the non-overlapping Segment fragments instead of inheriting blindly
of the state of the breaked up one. Gives some supplemental slack
that allows to converge.
- Note: Now the strategy is to disable the uses of GCellRoutingSet by
setting the expand step to 0.99. This induces only a slight slow
dow and memory increase and passes all the tests...
- Mark: This revision passes all the benches except for idct, vld &
ieee_division.
- Bug: In top CMakeLists.txt the SETUP_PROJECT_PATHS was not inserting
X_USER_TOP *before* X_TOP, thus potentially allowing an obsolete
system-wide configuration to shadow an up-to-date local one.
* ./kite:
- Change: In Configuration/KiteEngine, propagate changes in Configuration
in Kite. Note that a *second* singleton is created at Kite level.
- New: KiteEngine::printConfiguration() method to allow quick checks of
the router's main parameters.
- New: ConfigurationWidget to display/sets all the revelant Katabatic/
Kite configuration parameters. To be used with the TabSettings from
the ControllerWidget.
The ConfigurationWidget is bound to the default (static) Kite
configuration, as once it has been run you obviously cannot change the
router's settings.
- Change: In TrackFixedSegment, when the source/target coordinates of the
fixed segment are outside the grid (i.e. the Cell Abutment Box) truncate
them.
- Change: In GCell::addTrackSegment, when looking for overlap between the
to be inserted TrackSegment and Blockage segment, shrink the Blockage
span by one DbU to avoid false overlap when they are just edges connexes.
- Bug: In RoutingEvent::slackenTopology, in the local segment FSM, looping
on the MaximumSlack state. Now also checks the state count.
- Change: In TrackSegment::canMoveUp() & canPivotUp() adds the "reserve"
parameter and uses it in RoutingEvent to prevent over saturated GCells.
- Change: In Configuration, parameters adjustements: expandStep increased to
0.40. Makes RoutingSets biggers but no noticeable slow down.
- Change: In TrackSegment, _postDogLeg() & _postModify(), add segments to
"Ring" if they are directly connected to a RoutingPad. To maintain the
"border effect" after a topological slackening.
- Change: In GraphicKiteEngine, in the global routing relateds menus, suppress
the mention of "solution" as it might be unclear for an average user.
(just "Save Global Routing" or "Load Global Routing").
- Change: In RoutingEvent, conflictSolve1() tries to move up "other" blocking
segment before trying to break "self".
- Bug: In TrackSegment::reschedule(), remove from Track segments that are
now in a greater order than the current one. This bug was shown in the
TrackSegment::_postModify() method after a desalignate.
It was causing overlaps and/or routing completion false reports.
- Cleanup: In GCell, remove the DyKeyQueue support as it's been moved
to Katabatic level.
- Change: In NegociateWidow, increase the event stop thresold to 4M events
to be able to process the eFPGA matrix 16x16 (150K gates).
