* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* New: in Katabatic, in AutoSegment, recognize segments that are U-turn.
That is, based on two turn Contacts and going both top or bottom.
* New: In Kite, manage one pitch U-turn by making them diseapear from
the tracks. And make them same-metal when saving. Add a pack stage
to try to compact U-turn.
* Bug: In Kite, in TrackCost, the boolean attribute "_forGlobal" was not
initialized in the constructor causing the non-deterministic behavior.
Arrrrgggghhhhhh.
* Bug: In Kite, in PyKiteEngine, forgot to perform the
"balanceGlobalDensity()" in the layer assign Python wrapper, another
cause for non-determinism.
* Change: In Kite, In KiteEngine, print the configuration at the same
point as in the python script (to get identical output).
In Katabatic & Kite, remove all hard-coded values related to track pitches.
* New: In <Session>, add more convenience function to access RoutingGauge
characteristics.
* New: In <AutoSegment>, <AutoContact>, add support for the "depth spin",
that is, if the source/target contacts are going "top" or "down".
Used to compute the perpandicular pitch. Need a small modification
of the revalidation mechanism. The observers of <AutoSegment> are
notified when the spin changes.
* New: In <AutoSegment>, the getPPitch() method allow to compute the
"perpandicular pitch". For now it is simply the greatest from the
source perpandicular pitch and the target perpandicular pitch.
Make uses of the "depth spin".
* New: In <TrackElement>, <TrackSegment>, cache the perpandicular pitch.
Updated through the notification from the observable.
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.
- New: In NegociateWindow/RoutingEvent, adds a more comprehensive stage
"Repair". Perform in three stage: first try to place with a relaxed
constraint (one GCell on each side). Second try to minimize the faulty
segment. Third perform another "repack perpandicular" but this time
the faulty segment is re-inserted *before* any of it's perpandiculars.
- New: In RoutingEvent::cacheAxisHint(), when a segment has a parent, that
is comes for a "moveUp()", uses the parent axis hint as it's own.
- New: In State::slackenTopology(), in the global FSM, adds a special
operation when reaching MaximumSlack: forceOverLocals(), try to insert
the global on track containing only local segments. Should tend to
concentrate locals on a small set of shared tracks. Most useful on the
highest layers.
- New: In State::slackenTopology(), in the "MoveUp" state, try to find the
more appropriate segment to move up (Manipulator::desaturate()).
Effectively move up the longest segment fully enclosing the one we are
processing.
- New: In State::slackenTopology(), add a check for fully blocked segments
in the local segment FSM. Calls State::solveFullBlocked().
- New: In KiteEngine::createGlobalGraph(), decrease the vertical capacity
of one track inside the core. Helps smooth the vertical density.
- Change: In Manipulator::insertInTrack(), when a track is freed for a
to be inserted changes the priorities so that the segment is immediatly
inserted. Parallels ripeds and theirs perpandiculars are replaced
only *after*. This is the opposite of the previous behavior.
- Change: In NegociateWindow::NegociateOverlapCost(), account the costs
of terminals only for deep depth layers (M1, M2 & M3).
- Change: In RoutingEvent::insertInTrack(), expand the excluded interval
by a half-pitch (2.5l) instead of one lambda.
- Change: In State::State(), do not uses DiscardGlobal if the ripup count
exceed 5. Case of the "Strap" segments that can be ripped a lot
before changing state.
- Change: In State::_processNegociate(), no longer lock into position
(fixed) the local terminal segments as a last resort.
- Change: In RoutingEvent::_processNegociate(), no longer ripup perpandiculars
when a segment is inserted in a free space. Reduce the number of
events whithout degrading the routing quality.
- Change: In State::conflictSolve1_v1b(), if getLongestConflict() is nul,
ignore the track, the conflict must occurs on another track.
- Change: In TrackCost, add a flag support. First uses, a flags to prevent
a local of the topmost layer to ripup a global which is in moveUp
state.
- Bug: In State::solveFullBlockage(), after have been freed, reset the
segment state to "moveUp".
- Bug: In manipulator::minimize(), the axisHint was miscalculated if the
punctual span was empty.
- Change: Big cleanup. Supress all the GCell level: GCell, GCellGrid,
GCellRoutingSet. Blockages now managed inside the BuildPower.
- New: In NegociateWindow, Histogram of GCell densities in Gnuplot
format.
