Jean-Paul Chaput 95aba574a5 Happy New Year 2018 ! Update license years... 2018-01-06 17:55:44 +01:00
Jean-Paul Chaput 9808fb12b2 Solve the template lookup problem in tstream.
* Bug: In Hurricane, in tstream (Commons.h), in the *template* overload of
    operator<<(), do not use the operator<<() of ostream as it will be
    looked up in "stage 1" (template definition) and so will miss all the
    overloads added later and built over getString<>(). Instead, make use
    of getString<>(), which, as another template will be looked up in
    "stage 2" (template instanciation) and at that point will have all the
    needed template specialisation of getString<>().
      We also need to define new stream manipulators to be able to create
    a matching template overload not dependant from the implementation.
    To avoid name clashes, we prefix a 't'. For now, only 'tsetw()' is
    refined.
      As a side effect, we cannot directly print bit-fields into the stream,
    we must go through an intermediate variable (happens once in AutoContact).

Jean-Paul Chaput f68ac4d0e6 Argh. cdebug was slowing down the program too much.
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
    down the program (three times for Kite!). Create a macro cdebug_log
    which calls cdebug *only* if the debug level is active.
2016-06-11 21:56:12 +02:00
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 0699fb0a40 In Katabatic, no more segments with one fixed contact only.
* Bug: In Katabatic, in AutoHorizontal::_slacken() when slackening
    from a METAL2 terminal no longer set the terminal still on the
    terminal fixed. Instead use a the new feature of
    CntUserNativeConstraints.
* Bug: In Katabatic, in AutoContact, new flag CntUsernativeconstraints
    so the native constraint box is specified by the user constraints.
      This new possibility is needed because, if a Contact is fixed
    the native constraint box *is* bound to it's current position.
    But if the related segment is not fixed, and moved, it may move
    the Contact with him, loosing the original fixed position.
      Now we can remember the wanted position through the user
    constraints.
* New: In Katabatic, in GCellConfiguration new explicit management
    for 4 globals and one METAL2 (occured for the first time in the
    RAM generator).
2016-04-22 22:43:53 +02:00
Jean-Paul Chaput 798d1edb34 Bug corrections in Katabatic & Kite, bad bound index computation.
* In Katabatic, in GCellConfiguration, added support to 3G_2M2 (generic).
* In Katabatic, in GCellGrid, in getUSide() we were not using the correct
    contant set (Constant namespace instead of Kb...) so the size returned
    was always X. It doesn't show if the chip is square...
* In Kite, in Track::getBeginIndex(), if the position requested was enclosed
    in same net segments, we were going one index too far in the "previous"
    direction.
* In Kite, in Track::getOverlapBounds() we where going one index too far
    in the "next" direction while computing the "end" index.
2016-04-13 18:42:55 +02:00
Jean-Paul Chaput a78882fd5b Clocks in BLIF parser. In RSavePlugin, flags to select views to save.
* Bug: In CRL Core, in BlifParser, recognize clocks (Alliance patterns).
* Change: In Cumulus, in RSavePlugin, "kw" manage a new "views" to
    specify which views must be saved. Physical by default, but sometimes
    we need logical as well. If the design contains uniquified cells,
    save the logical view.
      In ClockTree, abort the clock tree building if the design has no
    top level clock.
* Change: In Katabatic, in GCellTopology, adds 2G_5M1 configuration.
* Bug: Kite, in BuildPowerRails, if we are not in a chip the nets
   composing the H-Tree must be protecteds be blockages.
2016-03-26 11:59:32 +01:00
Jean-Paul Chaput 1ef4bc122f Forgot to catch Bug exception. GCell manage 5 terminals of a Net.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
    forgot to catch the Hurricane::Bug exception which was leading to
    terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
    five metal1 terminal of the same net. This unlikely configuration
    did appear in the SNX for the first time...
2016-03-17 16:54:53 +01:00
Jean-Paul Chaput fce97bb1d9 Corrections in how to access pads terminals in Katabatic/Kite.
* Change: In Katabatic, in GCellTopology::doRp_AccessPad(), if the supporting
    RoutingPad is big (more than two pitch), do not put the access
    contact in the center but on the edge. This is to avoid cut violations
    between the VIAs and the matrix of VIAs that may be generated under the
    RoutingPad itself.
* Change: In Kite, in TrackSegment destructor, if the legnth of the wire,
    without extensions is less than one picth, enlarge it so it encompass
    it's source & target VIAs (to avoid notches).
* Bug: In Kite, in Track destructor, the TrackElements where detacheds,
    but not deleted, causing a memory link.
2016-03-02 17:15:58 +01:00
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 5dc60415e7 Happy new year 2015! 2015-03-17 16:56:55 +01:00
Jean-Paul Chaput 1f9ae36554 Bug fixes for MOSIS SCMOS_DEEP support.
* Change: In Hurricane, the NetRoutingProperty is moved into Hurricane
    from Katabatic. Needed for Knik to be able to access thoses
    informations.
* Change: In Hurricane, in RoutingPad::setOnBestComponent(), now in
    case of identical area, select the component of lowest id.
    This should not be needed if the component ordering was fully
    deterministic as it should be (will investigate later).
      This is to ensure that the choosen component is always the
    same, especially between save/load of a global routing.
* Bug: In Katabatic, in AutoContactHTee::updateTopology(), invalidate
    the segments only if the topology is valid (no NULL in the
    cached segments).
* Bug: In Katabatic, in GCellTopology::construct(), throw an error
    if the topology is bad instead of trying to continue (and core
    dump later... ).
* Bug: In Kite, in BuildPowerRails, distinguish the name of the master
    net in the pad (for vddi, vssi, vdde, vsse, ck, cki & cko) and the
    name of the net in the *chip* netlist. Must use the later to make
    comparison as they may differs.
* Change: In Knik, in save/load solution, exclude nets that are not
    globally routed by Knik. That is which NetRoutingProperty is not
    *Automatic*.
* Bug: In Cumulus, in chip.BlockPower take account of the layer
    width extention to sligthy shrink the connector thus avoiding a
    notch with standart cell in some cases.
* Change: In Cumulus, in chip.ClockTree disable the use of fixed Steiner
    trees for the leaf clocks, as it seems overconstrained for the
    router. First move was to lower them in M2/M3 (instead of M3/M4)
    but that was not sufficent.
* New: In Cumulus, RSavePlugin for recursively saving a physical
    hierarchy.
* New: In documentation, first embryo for RDS file. Should have been
    in Alliance git, but I prefer to keep newest doc in Coriolis.
2014-09-21 16:44:37 +02:00
Jean-Paul Chaput a3963716b1 Correction in plugins to support msxlib compatible pads.
* New: In CRL Core, in helpers & alliance.conf, set and read a "PAD"
    variable to define the pad model name extension ("px" for "sxlib
    and "pxr" for vsxlib, this is provisional).
* New: In CRL Core, in plugin.conf, add parameters to define the name
    of used for power & clock supply. We may remove the extention in
    the future (to be more coherent with the previous modification).
* New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no
    longer place the accessing contact *at the center* of the
    RoutingPad. It works under sxlib because buffers & registers all
    have same size terminals. But this is not true under vsxlib,
    leading to misaligned contacts & wires. Now systematically place
    on the slice midlle track (maybe with one pitch above or below).
      This is still very weak as we do not check if the terminal
    reach were the contact is being put. Has to be strenthened in
    the future.
* New: In Cumulus, in chip.Configuration.ChipConf, read the new
    clock & power pad parameters.
* Change: In Isobar (and all other Python wrappers), uses PyLong instead
    of PyInt for DbU conversions. In PyHurricane argument converter,
    automatically check for both PyLong and then PyInt.
* Change: In Cumulus, in chip.PadsCorona, more accurate error message
    in case of discrepency in global net connections (i.e. no net
    of the same name in instance model and instance model owner.
* Change: In Kite, in BuildPowerRails, when looking up at the pads
    model name to find "pck_" or "pvddeck_", do not compare the
    extension part. But we still use hard-coded stem pad names,
    maybe we shouldn't.
* Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there
    was a loop in the search of the best N/E initial RoutingPad.
* Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect
    RoutingPads of fixed nets, they are already through the
    BuildPowerRails stage (and it's causing scary overlap warning
    messages).
* Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create
    deep-plug when the core is flat (not sub-modules). All the new
    nets are at core level.
* Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure
    that the core is aligned on the GCell grid (i.e. the slice
    grid of the overall chip).
* Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop
    while looking for the bigger N-E RoutingPad. Forgot to decrement
    the index...
2014-09-13 17:45:30 +02:00
Jean-Paul Chaput 20d25b2053 Add NetRoutingState (Property) on Nets to tell Kite what to do.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
    with a state that indicate to Katabatic & Kite what to do with it.
    The possible states are:
    1. Fixed : all the wire are in fixed positions. The router cannot
       move them and account them as obstacles.
    2. ManualGlobalRoute : a user-defined topology is supplied. The
       wires still have to be detailed route in "Detailed Pre-Route"
       but will be skipped for the global routing and fixed for the
       general Detailed route.
    3. AutomaticGlobalRoute : ordinary nets, to be global routed then
       detail routed.
    4. Excluded : do not try to global or detail route thoses nets.
    5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
      Not all nets have this property, only those that needs a special
    processing.
      To ease the access to the state, it is nested inside a
    PrivateProperty in the net (NetRoutingProperty), with an extension
    access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
    net's states are strored inside an internal map for faster access.
    The property is *not* deleted when Kite is destroyed. The property
    will remains until the Net itself is destroyed.
      As a consequence, the lists that where passed to high level
    function are removed as the information can now be accessed directly
    through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
    step of Kite.
2014-07-02 14:36:58 +02:00
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 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.
2014-05-19 17:58:38 +02:00
Jean-Paul Chaput dda3f99fd8 Update documentation for compliance with doxygen 1.8.5.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
    and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
    copy some files like the javascripts and some images (open.png,
    closed.png). So we copy them from doxygen installation and make
    the CMakeLists.txt install them. I hope they will not change too
    much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
    correctly the formating we already adopted (with a left margin
    to put command into). Use HTML_EXTRA_STYLESHEET instead of
    HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
    top header. Enable dot for inheritance diagram. Set the
    EXAMPLE_PATH=. to include the synthetic hierarchy.
    Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
2014-05-13 16:30:41 +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.

Jean-Paul Chaput f6ab7b87f0 Compliance with g++ 4.8.1, support for devtoolset-2
Details:
* New: in <bootstrap>: add support for devtoolset-2 in ccb. Run the
    cmake commands through 'scl', set shell environment variables
    BOOST_INCLUDEDIR & BOOST_LIBRARYDIR and disable the default
    system path search.
* Change: In various flex scanners add the %nounput to suppress
    compiler warnings.
* Change: Little cleanup for g++ 4.8.1 as it's more strict.
* Change: In various top CMakeLists.txt, suppress extraneous '/'
    after DESTDIR.

2012-12-03 08:28:43 +00:00
Jean-Paul Chaput cbccf9e2a4 * ./katabatic:
- New: In LayerAssignement & GCell, perform layer assignment on whole net
        trunk, instead on a segment by segment basis.
    - New: In GCell, fragmentation analysis. When a layer change is requested,
        it allows to check if the additionnal perpandiculars created to
        maintain connexity will not over fragment the layer. This is particu-
        larly critical for M3->M5 which create M4 in perpandiculars, and M4
        may be subject to very dense configuration.
    - New: In AutoSegment & LoadGrByNet, adds a flags telling if the net's
        degree equal 2. Has not proven to be useful yet.
    - New: In AutoSegment, adds a flag telling if the segment is the perpan-

Jean-Paul Chaput 8faade8bc6 * ./katabatic:
- New: In AutoSegment, adds a "_parent" attribute to keep track of the fragmentation
        processus. Currently used only for strap segments, points to the original
        segment in the appropriate direction (before the split).
    - New: In GCell & LayerAssign, new method of layer assignment. Move up
        the whole net trunk if only one of it's segment is inside an over-saturated
        GCell. AutoSegment are moved up only if there is at least 2 free tracks
        remaining on the upper level.
    - Change: In Session::_canonize(), uses the lowest segment Id as canonical.
        More reliable than geometricals criterions in the end. Assuming that the
        segments are being created in deterministic order, which *should* be the
        case consediring the way we are walking through the global routing.
    - Change: In AutoSegment, completly suppress the CompareCanonical(), replace
        it by the much simpler CompareId().
    - Change: In GCell::rpDesaturate(), stops desaturation when bottom density
        is under 0.5, otherwise we are causing a severe imbalance in M2/M4
        densities. All wires pushed up to M4...
    - Change: In ChipTools, for the Pad's RoutingPad, reslect the best component
        using the one in the lowest layer. To avoid problem when splitting
        AutoContact as we expect the base Contact to be on the lower layer.
    - Bug: In GCellConfiguration::_GCell_xG_xL1_xL3(), add H/V alignement constraints
        in fork case. This allow NE/SW contact to be splitted correctly later.
    - Bug: In AutoContact::split(), the connexity on the splitted contacts was
        not correctly restored, leading to canonization and parentage looping
        errors. This was concealed by the Kite Track::_check() bug (incomplete
        individual TrackSegment checking).

Jean-Paul Chaput 629452dcc6 * ./katabatic:
- Change: In GCell & GCellGrid, unificated way of computing all the GCell's
        densities.
    - Change: In GCell::stepDesaturate(), uses shearUp() instead of moveUp().
    - Change: In AutoSegment, new method ::shearUp() to avoid moveUp() saturating
        GCells as side-effect.
2010-12-12 21:43:25 +00:00
Jean-Paul Chaput cf9a7a7911 * ./katabatic:
- New: ChipTools, regroup all datas and utilities to manage a full-chip
        design.
    - Change: In LoadGrByNet/GCellConfiguration::_GCell_xG_1Pad(), uses straight
        perpandicular wires on top & right pads. The GCells under those connectors
        are fully saturated, wires must go out as straight as possible.
    - Change: In AutoHorizontal/AutoVertical, update the "terminal" flag after
        slackening. This is to avoid global that are no longer connected to
        terminals behave as such.
    - Change: In AutoSegment::canMoveUp() & canPivotUp(), prevent all local segments
        to go up. This is to avoid cluttering upper levels with small segments.
    - Change: In GCellConfiguration, for xG_xL3, detect straight vertical topologies
        and for them to be fixed (new flag FIXED_GLOBAL set by the topological
        builder instead of the constructor). This prevent the router to do
        stupid things...
          To sets the "Fixed" flag *after* the axis of global segments have been
        positionned correctly adds a "_toFixGlobals" static table lookup.
    - Change: In GCell::stepDesaturate(), if less than one free track remains in
        the upper layer, do not move up the segment. This allows from a minimum
        free room for expansion.
    - Change: In GCell::_getString(), display indexes and layer names in various
        saturation tables.
    - Change: In AutoSegment, allow move up of local Segment. ::moveUp() and
        ::canMoveUp() arguments go from booleans to flags, which are more
        explicits.

Jean-Paul Chaput 36a99a53ae * ./katabatic:
- Change: In loadGlobalRouting(), more exlicit message as to why a net is
        filtered out the routing set (POWER, GROUND, CLOCK or BLOCKAGE).
    - New: ChipTool, module with utilities specific to chip routing. Containing
        a function to pre-break wires around a block.
    - New: In loadGlobalRouting/GCellConfiguration, adds supports for RoutingPad
        connected on chip's pad.
    - New: In GCellGrid/GCell, can compute the density in three modes: average,
        max of H/V and max of layer. Currently implemented in getMaxHVDensity(),
        should be unificated with getDensity(). Used for display purposes.
    - Bug: In AutoContact, when splitting a contact, add a specific check for
        "one layer span".
    - Bug: In AutoSegment::canMoveUp(), do not move up fixed segments.
2010-11-16 13:59:38 +00:00
Jean-Paul Chaput 38fb1dfdfb * ./katabatic:
- New: To pass the ibmXX, new parameter "katabatic.saturateRp" which allows
        to sets the threshold above which a GCell has too much RoutingPads in
        it and must be further desaturated. Must be 8 for FPGA, and 10 for ibm.
    - Bug: In LoadGrByNet(), when looking for the starting GCell, the computation
        of unconnecteds RoutingPads was incorrect, too great and letting the
        router believe that the routage was incomplete.

Jean-Paul Chaput 8bab63c864 * ./katabatic:

2010-05-13 09:46:14 +00:00
Jean-Paul Chaput 966de8279c * ./katabatic:
- Change: In KatabaticEngine, the containers used to store the "nets to
        route" is changed from a vector<> to a set<> sorted by the Nets names.
        Uses more memory but allows much faster Net deletion.
    - New: In _loadNetGlobalRouting(Net*), detect non-routed Nets. A Net is
        considered as unrouted if it's 10 first RoutingPads have no slave
        Segment. The Net is withdrawn from the set of Nets to route.
    - Bug: In GCellConfiguration::_GCell_1G_1L1(), correctly compute the
        access flag passed to _GCell_rp_Access().
    - Change: In AutoContact::restrictConstraintBox() adds "warnOnError"
        parameter to shut down warnings.
    - New: KatabaticEngine::_computeNetConstraints() now also returns a set<>
        of segments on which constraints are incompatibles. All the NetConstraints
        related functions are modificateds accordingly.
    - Change: In KatabaticEngine::_loadNetGlobalRouting(), create dogleg
        on overconstrained Segments computed by a call to _computeNetConstraints().
          Overconstraineds Segments can occurs when a global is directly
        connecting two punctual RoutingPads (see "ieee_division").
          As a side effect, and to avoid looping each Net is revalidated
        *before* making any dogleg. So Nets are revalidated one by one instead
        of alltogether.
    - Change: In AutoSegment::_toConstraintAxis(), do nothing if constraint
        interval is empty.

Jean-Paul Chaput 234175fa23 * ./katabatic:
- Bug: In KatabaticEnginge::_desaturate() (part of LayerAssign), reset
        the moved up Segment pointer between iterations. Suppress the warning
        about the GCell's DyKeyQueue beeing not revalidated on deletion.
    - Change: In LoadGrByNet, manage the 4G+3L1 configuration with the generic
        _GCell_xG_xL1_xL3(). Needed for "dct_lvl2".
2010-05-03 09:16:28 +00:00
Jean-Paul Chaput e7b1a5de6e * ./katabatic:
- Change: In Grid/BaseGrid, add an Abutment Box attribute (to facilitate
        segment truncation in Kite::TrackFixedSegment.
    - Change: In Grid/BaseGrid::Axis, when computing a row/column index using
        the graduation table, if the coordinate is exactly on the last
        graduation, return the last GCell instead of "out of bound".
    - Change: In GCell::hasFreeTrack(), AutoSegment::canMoveUp() &
        AutoSegment::canPivotUp() adds a "reserve" parameter to modify the
        amount of wirelength to remains free after the insertion.

Jean-Paul Chaput d98b31a856 * ./katabatic:
- Bug: In GCell, bad cast between <size_t> and <unsigned int>, showed only
        under 64 bits.
    - New: In KatabaticEngine::printMeasures(), adds a support for measurments,
        both time and memory size in Mb are stored for each tag.
    - New: Adds measurements "Gates", "GCells", "load" & "assign".
2010-04-17 10:14:22 +00:00
Jean-Paul Chaput 3069af8a63 * ./katabatic:
- New: In GCell & LayerAssign, adds a supplemental desaturation steps when
        a GCell containts too many (more than 7) RoutingPads in M1. This is
        especially useful for the eFPGA matrix with it's custom made cells.
