Jean-Paul Chaput 82cff69d9f Complete rewrite of the trace system (now a stream).
* 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.

Jean-Paul Chaput 1dafcbc882 UTurn management in Katabatic & Kite.
* 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.

Jean-Paul Chaput ed557d9027 Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
    vertexes in the grid (must not be used by the global router).
      Modificate the Graph::getVertex() method so that when a vertex
    is geometrically queried, if is a blocked one, return a non-blocked
    neighbor. This mechanism is introduced to, at last, prevent the
    global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
    A reduced segment is in the same layer as it's perpandiculars.
    To be reduced, a segments has to be connected on source & target to
    AutoContactTurn, both of the perpandiculars must be of the same layer
    (below or above) and it's length must not exceed one pitch in the
    perpandicular direction.
      To reduce an AutoSegment, call ::reduce() and to revert the state,
    call ::raise(). Two associated predicates are associated:
    ::canReduce() and ::mustRaise().
      Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
    to connect to the pads. Create wiring, fixed and non managed by
    Katabatic, to connect the pad connector layer to the lowest routing
    layers (depth 1 & 2). The former implementation was sometimes leading
    to gaps (sheared contact) that *must not* occurs during the building
    stage.
      Remark: This bug did put under the light the fact that the initial
    wiring must be created without gaps. Gaps are closed by making doglegs
    on contacts. But this mechanism could only work when the database if
    fully initialised (the cache is up to date). Otherwise various problems
    arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
    when anchored on a RoutingPad, now take account the potential rotation
    of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
    to reduced AutoSegment are *not* inserted into track to become
    effectively invisibles. When a segment becomes reduced, a TrackEvent
    is generated to remove it. Conversely when it is raised a RoutingEvent
    is created/rescheduled to insert it. All this is mostly managed inside
    the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
    mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
    Y coordinate of the chip size. Did not show until a non-square chip
    was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
    backward compatibility with the MIPS32 bench. Have to review this
    functionnality coming from the deprecated placeAndroute.py.
      In st_instance.py, no longer creates the Plug ring of a Net.
    In my opinion it just clutter the display until the P&R is called.
    Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
    user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py	.

Jean-Paul Chaput ef9936e87c Support for Net alias names. Blif parser enhancements.
* New: In Hurricane, In Net & Cell, support for Net aliases names.
    Use a structure based on a simple ring of NetAliasHook. The Net
    holds a global map, sorted by names of all the aliases of all Nets.
    Elements NetAliasesHook of the map are slaves of ring whose master
    is an attribute of the Net (it is *not* in the map, as the primary
    name of the Net).
      In case of merge, the aliases of both Nets are merged and the
    name of the merged one become an alias.
      The Cell::getNet() looks in both the Net map and the aliases to
    find a Net by name.
* Bug: In CRL Core, in coriolisInit.py, reoder the loading of the
    configuration files so the real technology is read as early as
    possible to set up the <gridsPerLambda> factor before any lambda
    is actually computed...
* Bug: In CRL Core, in AcmSigda, do not try to fed the file when it
    has failed to be opened. Throw a clean exception instead.
* New: In CRL Core, in Toolbox, add a NamingScheme object to convert
    a design into VHDL compliant names (mainly from Blif/Verilog).
    This is extensible in any case.
* New: In CRL Core, in BlifParser, slightly more informative warning
    messages. Align the loading progress information on the other
    parsers.
      Add a capability to select which component of the design will
    be returned, if there are more than one. Use the "." as separator.
    For exemple you can request "Processor.Alu", which will load
    the "Alu" component from the design in "Processor.blif".
      To be able to save a Blif loaded design, systematically convert
    all the name for VHDL compliance, as it is the format used by
    the Coriolis native files (vst).
      Export the Blif parser to the Python interface.
* New: In Kite, In NegociateWindow, add a counter of the number of
    remaining events. Gives an idea of the ETA...
* New: In Unicorn, in cgt.by, add an option to load a Blif design from
    the command line.
* New: In Cumulus, new RSave plugin to save both netlist & layout.
    Partly redundant with the previous one. Have to better organize
    that later.

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 2b243fc0ca In protectCagedTerminal() check that the METAL3 track is free.
* New: In Kite, in protectCagedTerminal(), check that the perpandicular
    top METAL3 track is free before inserting the fixed protection.
    They are added *after* the Pre-Routed stage and therefore we have
    to check they do not cross.
* Change: In Kite, in NegociateWindow, print statistics before fixing
    segment in the pre-routed stage to get correct results.
* Change, In CRL Core, in Measures when an addMeasure is performed
    twice, let the new data erase the previous one (instead of keeping
    the previous one).

Jean-Paul Chaput ff21d3c8a2 Implementation of pre-routing support (for clock-tree compliance).
* New: In Katabatic, in <AutoContact>, this class is no longer derived
    from ExtentionGo. With the simplificated AutoContacts, there is no
    reason to do so, and it will save some QuadTree insertions/deletions.
      New factory function AutoContact::createFrom(Contact*) which try to
    build an AutoContact on top of a Hurricane::Contact. Of course that
    base contact *must fit* into one of the predefined Contact
    configurations (Terminal, Turn, HTee or VTee).
      NOTE: This implies that the pre-routed segments & contacts *are*
    correctly articulated, which is not the case when a Cell is read
    from disk in "ap" format. The pre-routing feature must be used for
    now without any re-read from disk. We will implement a re-articulating
    pre-process in the future.
* Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache()
    method now display an accurate error message if a segment is connected
    but has no AutoSegment conterpart (i.e. the lookup fails).
* New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is
    short-circuited for pre-routed segments, the optimal axis position is
    considered to be the one it is currently on (i.e. we trust the designer).
* New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting()
    method now accept a map of excluded nets (same as Knik). This map is
    the one of pre-routed nets.
* New: In Katabatic, in layer assignment, do not try to displace fixed
    segments...
* New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related
    methods to know if a segment comes from the global router (Knik) or
    is pre-routed (supplied by the user).
* New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed
    nets.
* New: In Kite, In <GraphicKiteEngine> new menu entry for running the
    router on pre-routed nets ("Detailed Pre-Route"), also integrated
    in the all-on-one route command.
* New: In Kite, In KiteEngine, new method ::_initDataBase() that group
    all the initialisation steps. It is a mix of calls between Knik and
    Kite initializations which are intertwinneds (may have to devellop
    a shared common base at a later point). It creates the Knik grid,
    then the Katabatic grid, then load pre-routed wires and power rails
    and protect isolated RoutingPads.
      Add support for a map of pre-routed nets (to be excluded for
    Knik calls).
      The method "::run()" now uses function flags, firstly to know if
    it is managing pre-routed wires or general purposes ones.
* New: In Kite, in <NegociateWindow>, the "::run()" methods has now two
    modes. The normal one and the 'KtPreRoutedStage' that is for routing
    pre-routed nets. When in pre-route stage, the wires are fixed at the
    end of this step.
* New: In Kite, in <TrackElement> add decorator for AutoSegment
    isUsedDefined().
* New: In Kite, in <TrackSegment>, the various ::canDogleg() methods
    returns false for a pre-routed (user-defined segment).
* New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().

Jean-Paul Chaput cd9d3fc4b6 ExtensionCap support and source/target terminal flags in Katabatic & Kite.
Placement management:
* Change: In <metis>, always disable the hMetis support regardless of
    it being detected or not as the placer is still unable manage the
    final bin contents.

Routing gauge management:
* Bug: In CRL Core, <vsclib/alliance.conf>, set the correct pitches and
    size for the routing layers and the cell gauge.
* Change: In Katabatic & Kite, extract the correct extension cap for each
    routing layer from the layers characteristics (cache then in
    Katabatic::Configuration).
* Change: In Katabatic, <AutoSegment>, create segment with the wire width
    defined in the gauge. For AutoSegment created on already existing
    Segment from the global routing, adjust the width.
* Change: In Katabatic, <AutoSegment>, more accurate information about how
    a segment is connected to terminal via source and/or target.
    The flag SegStrongTerminal is splitted into SegSourceTerminal and
    SegSourceTarget (but still used as a mask). So now we can know by
    which end an AutoSegment is connected to a terminal.
* Change: In Katabatic, ::doRp_Access(), create constraint freeing segments
    not only when HSmall but also when VSmall (more critical for <vsclib>).
    Otherwise we may see AutoSegments with incompatible source/target
    constraints.
* Change: In Kite, BuildPowerRails, do not create blockage on PinOnly
    layers *but* still create power rails planes. This is a temporary
    workaround for <vsclib> where the METAL1 blockages overlaps the
    terminals (it was fine for Nero, but they shouldn't for Kite).
* Change: In Kite, <RoutingEvent>, if a TrackSegment is overconstrained,
    directly bybass it's slackening state to DataNegociate::Slacken.
    Also rename the flag "_canHandleConstraints" to "_overConstrained",
    seems clearer to me.

Miscellaneous:
* Change: In CRL Core, <Utilities>, add a "pass-though" capability on the
    mstream to temporarily make them print everything.
2014-05-25 15:00:35 +02:00
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.

2012-12-03 08:29:28 +00:00
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.
2011-01-25 17:16:50 +00:00
Jean-Paul Chaput c19429108e * ./kite:
- New: In RoutingEvent, while routing a full chip, transient full blockages
        may happens due to the initial position of some perpandiculars on theirs
        optimal positions. Check for it and perform a "ripupPerpandicular" with
        the perpandiculars re-routed first (on normal operation, this is the
        reverse).
    - Change: In NegociateWindow::NegociateOverlapCost(), do not account terminals
         if the layer is *above* METAL3 as it is unlikely that it's truly directly
         connected to a terminal (true at least for our designs).
    - Change: In RoutingEvent::State, add a "fullBlocked" flag to perform the
        full blockage direction while building the state object.
    - Change: In RoutingEvent::cacheAxisHint(), when the TrackSegment has parent,
        uses the parent current axis position and not it's axis hint.
    - Change: In Manipulator::insertInTrack(), when the overlapped segment is a
        Local and is completly enclosed (shrinkLeft & shrinkRight), no longer
        rip it up but force a shrink left/right instead. 
    - Bug: In RoutingEvent, the event sorting function was sorting in the *wrong*
        order! The less prioritary first! With the correct sort, we won an
        additionnal 30% in speed (total: 69%). From the "reference" time we have
        a 3.2 speed-up. And we can successfully process denser designs...
2011-01-09 18:08:57 +00:00
Jean-Paul Chaput 3c9d064fd8 * ./Kite:
- New: In BuildPowerRails, special processing for the power ring segments.
        The "diagonal" of vias at each corner is causing a misbehavior of the
        routing algorithm (due to fully saturated GCells in one direction).
        As a temporary fix, extend the segments so they form a "square corner".
        (problem arise on "d_in_i(22)").
    - New: In RoutingEvent::_processNegociate, disable the "isForcedToHint()"
        feature. No noticeable loss of quality or speed.
    - New: In TrackElement/TrackSegment, wraps the AutoSegment parent's mechanism.
        Allows to gets the DataNegociate of either the segment or it's parent.
    - New: State::solveFullBlockages(), dedicated method to solves the case when
        all the allowed tracks of a segment are blocked, tries to moves up
        local segments and to break-up global ones.
    - New: RoutingEventLoop, a more sophisticated way to detect looping.
        Maintain a dynamic histogram of the last N (default 10) segments routeds,
        with the count of how many times they have occurred. If that count
        exeed 40, we *may* be facing a loop.
    - Change: In State::conflictSolve1, implement new policy. The global segments
        no more can be broken by local ones. The idea behind is that breaking
        a global on the request of a local will only produce more cluttering
        in the GCell. Globals must be keep straigth pass through, especially
        inside near-saturated GCells. Globals breaking however can occurs at
        another global's request.
    - Change: In TrackCost, implement the new policy about locals segments that
        cannot break globals segments. The sorting class now accept flags to
        modulate the sorting function. Two options avalaibles: IgnoreAxisWeigth
        (to uses for strap segments) and DiscardGlobals (to uses with locals).
    - Change: In TrackCost, the "distance to fixed" have now an upper bound of
        50 lambdas (no need to be greater because it means it's outside the
        begin & en GCells). Take account not only of fixed segment, but also
        of placed segments which makes bound.
    - Bug: In Track::_check(), while calling each individual TrackSegment check,
        uses it as the *first* argument of the "or", otherwise it may not be
        called.
    - Bug: In ProtectRoutingPad, loop over segment Collections while modificating
        it was producing non-deterministic results. The fact that a collection
        must be not modificated while beeing iterated is becoming a more and more
        painful problem.

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.

Jean-Paul Chaput 23fc3e7b79 * ./kite:
- 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.

Jean-Paul Chaput 551adf4213 * ./kite:
- 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.
2010-08-22 12:38:27 +00:00
Jean-Paul Chaput 5705929dc8 * ./katabatic, ./kite:
- Bug: In Configuration, discrepencies of parameter types.
2010-06-22 13:59:22 +00:00
Jean-Paul Chaput 37b4e5b423 * ./kite:
- 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.

Jean-Paul Chaput 6a3440f4e6 * Most of tools:
- 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.
2010-04-28 15:44:07 +00:00
Jean-Paul Chaput b2c3c68601 * ./kite:
- 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.
2010-04-23 13:14:17 +00:00
Jean-Paul Chaput 974b29b8a7 * ./kite:
- 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.

Jean-Paul Chaput a515d42757 * ./kite:
- 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).
