Jean-Paul Chaput 0cced62851 Kite is now deterministic, given a global routing.
* 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).

Jean-Paul Chaput 2dd36b9624 Support of RoutingGauge, part 2.
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.

Jean-Paul Chaput c8bcfdf174 Improved UpdateSession & exception catching. Start of RoutingGauge implem.
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.

Jean-Paul Chaput ac85c0cca4 * ./kite:
- New: Whole replacement by Kite3.

Jean-Paul Chaput 23e61de0e3 * ./kite:
- New: In RoutingEvent::State, in the local segment FSM, if a local terminal
        segment is fully blocked, try at least one dog leg.

Jean-Paul Chaput 17f3207d71 * ./kite:
- 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.

Jean-Paul Chaput c9e1c3101a * ./kite:
- 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.
