Jean-Paul Chaput 7bcf47212b Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
    With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
    routing configuration that was not efficiently handled did appear.
      While the preferred routing direction for metal1 is officially
    horizontal, due to the way the standard cell must be designed,
    their metal1 terminals are still verticals (or punctuals).
      Thus, when connecting to them, we face the case where the metal1
    terminal (RoutingPad) is vertical *and* the metal2 wire is also
    vertical. With that setup, the position of the AutoContactTerminal
    via12 cannot be deduced, it may range all the way over the
    metal1 RoutingPad. What may define it's position is the metal3 the
    metal2 finally connects to. That, is, when we have one horizontal
    (the metal3) and one vertical (the metal1 RoutingPad).
      The intermediate wire of metal2 can be kept to a minimum size
    by "dragging" the via12 close to the via23 when the metal3 wire is
    moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
    RoutingPads in metal1 is managed first in PreProcess by restricting
    the span of the connecteds metal3 and in _makeDogleg also by restricting
    the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
    Automatically check if the connecting segment is in the same
    direction as the RoutingPad, if so, sets the "SegDrag" flag.
      The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
    The drag state can be known with the "::isDrag()" predicate.
      In "::_makeDogleg()", when making a dogleg on a dragable segment
    pass the drag state correctly and restrict the perpandicular span
    of the perpandicular to the RoutingPad (though segment user constraints).
    If we make a dogleg on the metal2 is it likely than we cannot go
    straigth out vertically from the RoutingPad, so the new perpandicular
    *is* restricted to the RoutingPad span.
      Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
    hole where to minimize a draggable segment. We finally did not use it,
    but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
    function to check for vertically aligned metal1 RoutingPads, in that
    case setup user constraints on the metal3 segments so they cannot
    completly cover the other RoutingPad with metal2.
      We also keep a "metal2protect()" function that create a fixed segment
    to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
    This allows us to request the creation of a locking (fixed segment)
    over a draggable segment. Not used for now.
      Lock events are processeds before all others as they create new
    TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
    method to find the nearest free interval in a Track after/before a
    position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
    constraints *only* if it's not an empty interval (as we use min/max
    functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
    must be inverted. Seems it never worked, but we never used it until
    now...

Jean-Paul Chaput 95aba574a5 Happy New Year 2018 ! Update license years... 2018-01-06 17:55:44 +01:00
Jean-Paul Chaput 9b2648241d In Anabatic/Katana, add support for VH gauges (real technos).
* Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(),
    when the anchor is a RoutingPad (which must be always the case),
    perform the true computation of it's position based on the
    segment occurrence. It is a important change, previously the
    area was in fact the "center line" of the connector while now
    it is really an area (mandatory for "half-offgrid" terminals of
    real technologies).
      The change is not complete yet, the area should be shrinked
    by the half size of a VIA, because the area applies to the center
    coordinate of the VIA (to be done quickly).
* Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg
    is created (restore connexity after a layer change) the layer of
    the VIA, based on the segments it connects to must be re-computed
    *after* the dogleg has been made.
* Change: In all files of Anabatic, when comparing two layers, no longer
    use the Layer pointer itself, but the layer mask. This allow a
    transparent management of both real and symbolic layers (which
    do share the same mask). Real metal layers (not VIAs) will be
    BasicLayer and symbolic metal layers will be RegularLayer.
* New: Anabatic::Configuration::selectRpComponent(), select the best
    RoutingPad component for metal1 terminals. Look for the metal1
    component with the biggest accessibility on-grid.
      RoutingPad using other metals are left untoucheds.
* New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the
    neighbor Vertex through an Edge*. This method allows to write
    clearer code as we no longer need to access the neighbor through
    the underlying GCell.
      Also add proxies for GCell methods in Vertex.
* Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when
    a component with multiples vertexes is reached *and* two of it's
    vertexes are reached *at the same time* (one from which we backtrack
    and one still in the queue) extraneous edges may be created by
    _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1".
      To solve this, Dijkstra::_toSource() is modificated, the "from"
    edges of the newly reacheds vertexes are reset to NULL, *except*
    for the one we will be backtracking from. That is, the one given
    in the source argument.
* Change: In Anabatic::NetBuilder class, put the various Hooks and
    RoutingPad sorting functions as class ones.
* Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag.
    This unset flag was causing AutoContactTurn::updateTopology()
    to not work as expected and making gaps, this was the cause of
    the last remaining warnings about layer connexity.

Jean-Paul Chaput eae5d6bf83 Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
    workaround for a Hurricane problems. When an instance is moved, the
    RoutingPads that use it must be moved accordingly, but they are not
    invalidated so they stay in the wrong QuadTree.
      New method ::_resizeMatrix() to be called when the associated Cell
    is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
    the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
    now return a boolean to tell if it was ok (must not encounter a NULL
    GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
     - getDHorizontalLayer()
     - getDhorizontalDepth()
     - getDHorizontalWidth()
     - getDHorizontalPitch()
     And so on for Vertical and Contact.
       They supply depth-independant informations about the H/V layers to
     build the initial detailed routing.
        The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
    for implementing 2-Metal blocks.
      Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
    move the contents of GCell::updateContactsPosition() into it and
    suppress it.
      WARNING: In case of a GCell shrink this may cause problems. But for
    now we only expand...
      New method GCell::getNetCount() to count the number of Net going
    though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
    routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
    calls by "not gcell->isAnalog()". Add more check so that the methods
    pertaining to the analog routing (GRData) are not called in digital
    mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
    cases. That is, always break in case of vertical pass-through or
    U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
    to ensure the revalidation. The "::revalidate()" method is then moved
    as "::materialize()" (overload of Go) and "::_invalidate()" becomes
    "::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
    * ForkStack is now an object attribute as many methods do need it.
    * To push segments/hook on the stack, a new method "push()" is
      available. Perform NULL and fromHook checking. Can also setup
      _southWestContact or _northEastContact if it is the "from" edge.
    * N/S/E/W edges are now vector as in digital channel mode there
      can be more than one.
    * Added build topological build methods:
      - doRp_2m_Access() RoutingPad stem access.
      - _do_2m_1G_1M1() North or south access.
      - _do_2m_2G_1M1() North AND south access.
      - _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
    friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
    for channel routing, calls to setupPowerRails() and
    protectRoutingPads() must be called after the core block has
    been fully dimensionned.
      ::runGlobalrouter() contains the code tasked with the grid creation
    and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
    May be expanded for over-the-cell routing in the future.
      Added methods :
      - isDigitalMode()
      - isAnalogMode()
      - isMixedMode()
      - isChannelMode()
      - getBlock() / addBlock()
      - setupChannelMode()
      - createChannel()
* New: In Katana, new class Block to manage core blocks and perform
    channel routing.
* New: In Katana::Session, new convenience method "isOpen()".

Jean-Paul Chaput cafced2bf8 Katana manage wide wires, and they can also be symmetric.
* New: In Anabatic::AutoContact and the derived classes, manages wide
    wires. The contact self dimension itself according to the segments
    it is connected to. Special case for the AutoContactTerminal which
    also read the size of the component it is anchored upon.
      New refresh method "updateSize()" and flag CntInvalidatedWidth.
    to compute the size.
      In AutoContactTerminal, compute the constraint box according to
    the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
    attributes of the class. The flags are stored into a uint64_t as
    they are more than 32.
      Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
    uses the simpler overload of AutoSegment::create() in order to detect
    the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
    into a one-track method and a segment level method that iterate over
    the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
    to a specific track. So the base functions have now two parameters:
    "icost" and "itrack" (has a cost can have multiple tracks in the case
    of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
    it's track, as for a wide segment it will not be meaningful for the
    non-base track. This means that we have to use the Track::find()
    method each time instead.
      Remove the wide flag, as it is a duplicate of the one in AutoSegment.
      Added a getTrackCount() method to tell the number of track the
    segment is inserted into. Needed in the Track destroy step to delete
    a segment only when the last track that refers it is destroyed.
      Added getSymmetricAxis() to correct the computation of the symmetric
    base track in case of wide segment as the base track is not centered
    but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
    track span.
* Change: In TrackSegment::create(), now activate the factory and create
    wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
    problem (ever shifting to the right).

Jean-Paul Chaput 8d4fdf3471 TrackCost clean support for symmetric and wide segments.
* New: In Katana::TrackCost, the TrackElement and it's optional
    symmetric are now kept as attribute of a TrackCost. The cost
    is completly computed inside the constructor.
      TrackCost now support any mix of symmetric event and wide
    segments.
      The cost is now computed by adding directly to the current
    one instead of creating secondaries that are merged afterwards.
    As a consequence, remove all copy construction and merge
    capabilities.
      All the various methods used to compute the cost are renamed
    "addOverlapcost()" in all the various related objects.
      As a reminder, the overal cost method call is as follow:
        1. TrackCost constructor on a TrackElement.
           2. Call TrackElement::addOverlapcost()
              3. For all Track under the TrackElement, call
                 Track::addOverlapCost()
                 4. For all other TrackElement intersecting with
                    the overlap interval call:
                    TrackElement::incOverlapCost()
                    5. The callback overlap function for segments
                       is called (defined in NegociateWidow).
      Don't confuse:
      - TrackElement::addOverlapCost(), which compute the cost of
          inserting the segment inside a track (or a set of).
      - TrackElement::incOverlapCost(), which compute the cost of
          overlaping with this already inserted segment. It is the
          other way around of the previous one.
* Change: In Katana::SegmentFsm, use a vector of pointer to TrackCost
    instead of an object to avoid copy construction.
2017-06-10 12:27:25 +02:00
Jean-Paul Chaput 8a73b03fd8 Synchronize priority of TrackSegments connecteds through doglegs.
* Bug: In Anabatic::Dijsktra, correct the indentation in cdebug calls
    (lots of them causing a big shift right).
* New: In Anabatic::TrackSegment, new helper structure SideStack to
    manage a set of aligned GCells and their various sides sizes.
* Change: In Anabatic::TrackSegment::computeOptimal(), more accurate
    computation of attractors from global segments and variable size
    GCells using SideStack.
* Change: In Katana::DataSymmetric::checkPairing(), increase the tolerance
    for misaligned symmetrics from 2 to 5 tracks (should be enough for our
    narrow channel routing).
* New: In Katana::TrackSegment, add a first flag to enable locking of
    priority. If it is set, calls to either "computePriority()" or
    "forcePriority()" will have no effect. Added the uint32_t flags
    paraphernalia.
* New: In ::computeNetPriority(), overall function to control the call
    of TrackSegment::computeAlignedPriority(). The call is done from
    NegociateWindow::run().
* New: Katana::TrackSegment::computeAlignedPriority(), order the
    TrackSegments aligneds through doglegs to the one with the highest
    priority is routed first and others progressively from him. Done by
    forcing an ever decreasing priority on the aligneds ones.
      The amount of decrease is small so the aligned segments got routed
    (ordered) in close, if not contiguous, sequence. Priority is locked
    for the order to remain.
* Bug: In Katana::TrackSegment::computePriority(), correct computation
    of the priority when there is more than 10 free tracks
    (a DbU::toLambda() call was missing, leading to very big priorities).
* Change: In katana::TrackCost CTOR, do not compute a distance to fixed
    in the case of analog segments, this is backfiring.
      Slight change of the compare function when delta differs. Seems
    to improve a little.
2017-05-30 22:33:06 +02:00
Jean-Paul Chaput 1e49da1976 Select S/T in AutoSegments_Aligneds. Priority moved to TrackSegment.
* In Katana::AutoSegments_Aligneds, allow the the caller to select
    if we are propagating through source or target only (or both).
    Note that if no flag is given, it is assumed that we want to
    propagate the old way on both source and target.
* In Katana::TrackElement, Katana::TrackSegment and Katana::RoutingEvent,
    move the event priority from RoutingEvent to TrackSegment.
    Add accessor and mutators associated in TrackElement (virtual
    methods).
2017-05-27 20:35:28 +02:00
Jean-Paul Chaput 3e825cc228 Katana routing algorithm adjustements for analog routing.
* Bug: In Hurricane::Interval, the ::getSize() method was returning a negative
    length when the Interval was empty. Now return zero. This was causing
    slight cost functions side effect when computing the overlap of a segment
    with another one belonging to the same net (i.e. shareDelta)
* Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal
    position for the axis is indeed inside the GCell interval.
* Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink
    applied to GCells sides. Interval are of the type [min:max[ so after
    symmetric transformation they become ]smax:smin]. Apply a correction so
    that they are [smax:smin[ and could be merged with the paired interval
    (the one without symmetry applied).
* Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive,
    and must be *substracted* to the "delta" (not *added*).
* Bug: In Katana::_computeNetOptimals(), now skip the already processeds
    AutoSegments instead of re-processing them.
* New: In Katana::AutoSegment::computeOptimal(), improved computation of
    the axis hint:
      - For analog net, propagate through the simple doglegs to find
        attractors.
      - Restrict the allowed interval to the union of GCell sides and
        segments constraints that are terminals.
      - Consider a local as "long" if it's length exceed 20 the P-pitch.
        (maybe make that a tool parameter).
2017-05-23 00:20:31 +02:00
Jean-Paul Chaput e78c3f21ef Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
    to allow different behavior between digital and analog modes.
      For "Aligneds" and "Perpandiculars" collections, now manage a new
    Flag WithDoglegs to follow aligned globals through local doglegs
    (for analog nets).
      Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
    part of an analog net.
      Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
    objects and *not* uint64_t. This avoids overload resolution problems with
    arithmetical overload of the operators.
      The BaseFlags/Flags types are now completly "isolated" from the
    uint64_t, it has the advantage of showing where unwanted previous implicit
    conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
    of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
    to allow to substract the topmost and rightmost track for axis span
    computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
    for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
2017-05-20 12:33:12 +02:00
Jean-Paul Chaput d07cdf03e9 Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
    the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
    as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
    makes the number of flags tip over 32 bits, thus making mandatory
    to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
    Flags::WithDoglegs to allow to propagate through global segments that
    are connecteds via doglegs on local segments. Meaning that there is
    a good chance that they could be aligned.
      Slighly change the way we propagate on aligned segments: no longer
    check for VTee or HTee, but only for same direction and layer as
    master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
    variants by the less implementation ambiguous "int32_t", "int64_t"
    (and variant). This should help to better detect bit trucation in
    flags.
      Use the type to give a hint about the flags kind:
        - Type "Flags", for flags shared among Anabatic & Katana
          functions/methods (may also appear in some objects states).
        - Type "uint32_t" for flags belonging to an object internal
          state of from Hurricane functions flags (those should be
          grouped in a Flag subclass in a perfect world).
2017-05-16 14:53:33 +02:00
Jean-Paul Chaput ef69a6d586 Support for symmetric routing in Anabatic/Katabatic.
* New: In Katana::SegmentFsm, the object is now able to handle two events
    at the same time. The master and it's symmetric. When there is no
    symmetric, the corresponing data is just left blank. This makes a
    bigger object, but as there is only one when running, it is not an
    issue.
      Candidates tracks are now an vector of array<2> (pairs), the
    TrackCost::Compare() functor has to be wrapped through CompareCostArray.
    The compined TrackCost of the two tracks is accumulated into the first
    element.
      Everything related to events gets duplicated: _event is now _event1
    and _event2, and so on.
      As there can be now two Manipulator actions done with SegmentFsm,
    this class now completly hide the Manipulator level from the
    RoutingEvent processing.
      New function ::bindToTrack() to perform the track insertion.
* New: In Katana::TrackCost, add a new ::merge() function.
* New: In Katana::TrackElement and Katana::TrackSegment, add symmetric
    management. Allows to know if a TrackElement has a symmetric and to
    access it.
* New: In Katana::DataSymmetric, add new overload for ::getSymmetrical()
    to handle DbU::Unit and intervals.
* Change: In Katana::RoutingEvent, remove all direct uses of Manipulator
    objects. Now any change to the event associated segment must go through
    call to Segment Fsm.
* Change: In Katana, adjust the debug level so internal informations are
    put below level 156.
* New: In Hurricane::DbU, in ::getValueString(), special display when the
    value is Min or Max (more helpful than a gigantic number).
2017-04-30 23:46:33 +02:00
Jean-Paul Chaput b99a362509 Apaired segments building for symmetric routing (step 1).
* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
    unsigned int because we start to need more than 32 different flags
    in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
    std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
    measurements) displaced from Katabatic. This way all ToolEngine
    can use this feature. The _postCreate() method display the
    memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
    builtin timer (remove the local one). Forgot to call the base
    class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
    builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
    Collection allows a deterministic walkthough *all* the AutoSegments
    connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
    AutoContactTerminal is the *only one* anchored on a RoutingPad,
    thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
    Created new class DataSymmetric to store symmetric information
    of a net (mainly the paired AutoSegments).
      Added KatanaEngine::runSymmetricRouter(), for now only build
    the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
    symmetric information building the non-symmetric routing.

Jean-Paul Chaput dc46340d6a Redesigning access to analog terminals in devices.
* New: In Anabatic::AutoContact, added forceOnGrid() method to allow
    a AutoContactTerminal to be set (and fixed) outside it's constraint
    Box. Be aware that this may generate gaps in the routing.
      Stored using the UserNativeConstraints mechanism.
* New: In Anabatic::Session() new method getNearestgridpoint() to
    easily compute the nearest grid point from a position.
* Change: In Anabatic::AutoSegment::_revalidate(), use layer mask to
    compute the spin of the segment instead of the layers (more robust
    for analogic).
* New: In ::GCellTopology::doRp_Access() new method to create terminal
    contacts in _doDevice(). Issue more warnings and force the terminal
    to on grid (even if it create gaps). This a temporary hack.

Jean-Paul Chaput 47c9961ef3 First intergration of the Analogic router parts.
* New: In Anabatic::AutoSegment, introduce a the kind (associated to a
    flag) "LongLocal". Analog GCells can be very wide, so at least some
    carefuly choosen long local segments must be took into account as
    attractors in the computation of the optimal axis.
* New: In Anabatic::AutoSegment::computeOptimal(), take LongLocal into
    account as attractors.
* Change: In ::GCellTopology constructors compare the layers of the
    RoutingPads using layer masks instead of Layer pointers. Allows to
    find both "METALx" (symbolic) and "metalX" (real).
* Change: In ::GCellTopology::_doHChannel(), _doChannel(), _doStrut()
    and _doDevice(), tag long locals as "LongLocal". This need to be
    reviewed as it as bind done a bit too quickly.
* Change: In Anabatic::AutoSegment, due too a much bigger span of the
    analogic GCells the _optimalMin & _optimalMax bitfields must use
    16 bits instead of 8 (they where overflowed).
* New: In Katana, reorganisation of the initialization procedure to fit
    both digital and analogic cases. Create an analogInit() method.
* Change: In Katana::RoutingEvent, the _tracksNb and _tracksFree bitfields
    where too short for the Analog GCell size, now uses 16 bits instead of
    6.
* Bug: In Katana::GraphicKatanEngine::drawGCell(), skip drawing of a
    GCell if *both* width and height are under 150 pixels.
* New: In Katana::Session, add a new isOpen() method.

Jean-Paul Chaput bff9a38742 Forgot to perform Track re-order after removing zero-length segments.
* Change: In Anabatic::Autocontact, replace getMinDepth() and
    getMaxDepth() by getDepthSpan().
* New: In Anabatic::AutoSegment::canMoveUp(), add an optional check of
    low up density (Flags::CheckLowUpDensity). Allows to move up a
    segment if the up density is (very) low, and in this case it's more
    efficient than breaking it to fit in the lower layer.
      canMoveUp() is now able to perform the same work as canPivotUp()
    if *not* supplied the flag Flags::IgnoreContacts.
* New: In Katana, in GlobalRouting::DigitalDistance() now take into
    account the cost of a VIA (currently set to 2.5). Need to known the
    Net currently routed in the DigitalDistance object itself.
* Change: In Katana::Track::Element::canPivotUp(), now also takes a flag
    parameter.
* Change: In Katana::Manipulator, new flag IgnoreContacts to mirror the
    one of Anabatic.
* Change: In Katana::SegmentFsm, allocate once a Manipulator object instead
    of many times on the fly.
      In SegmentFsm::_slackenGlobal(), in the slacken state, if the up
    density is (very) low, bypass to move up instead of slackening.
    This solve better the routing of the control part of the register file.
    The register file having a pathological case of terminal placement:
    many punctual terminals aligneds in METAL2 *and* a grid of METAL2 and
    METAL3 blockages near below...
* Bug: In Katana::Session::_revalidate(), after removing the zero-length
    segments, forgot to re-order the track, leading to many stranges effects
    as the indexes where no longer coherent in the Track.

Jean-Paul Chaput 92522fef0b Solved more problems related to GCell not owning north/east boundary.
* Bug: In Anabatic, in AutoHorizontal & AutoVertical, native constraints
    must use GCell::getConstraintsUMax().
* Bug: In Anabatic::GCell, correct terribly bad implementation of
    both getConstraintUmax().
      In getSide(), use getConstraintUMax().
* Bug: In Anabatic::AutoContact, setCBUMax() must be set using the GCell
    getContraintUMax().

Jean-Paul Chaput cbb5e8781d In AutoSegment slackening, bad positioning of the perpandicular. 2016-08-28 19:09:07 +02:00
Jean-Paul Chaput 22bf92af2c Forgot to switch terminal flags when orienting AutoSegments (again!). 2016-08-28 16:12:05 +02:00
Jean-Paul Chaput 48f3a2bc3c Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
    pointer is NULL, do not try to access the owner. Returns NULL, so
    the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
    cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
    the constraints from the source AutoContact, as it holds the constraints
    transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
    It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
    completly oustside the cell abutment box and truncate the coordinates
    to the part that is inside. Use the "shrink" if we reach the east/north
    border.
* Change: In Anabatic, in Configuration, no more decorator because we will
    use a true derived relationship. Katana *derives* from *Anabatic* and do
    not *decorate* it, so the Configuration can do the same. It also implies
    that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
    in a standalone fashion (with a static method). Instead it must be opened
    using the relevant method of the Anabatic/Katana engine. This ensure we
    are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
    is not part of the collection by default, but will be included if the
    Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
    Declared in the header and initialized in the module. This is to prevent
    the fact that on some cases, in relation with the Python "extern C" part
    modules, we need a true allocated variable. It was causing weird linking
    problems.
      A side effect is that they can no longer be used as entry is switches,
    have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
    the grid type... Back annote all the edges capacity (north & east) with
    the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
    "Katana" for Kite-Analogic. When it's capabilities and performances
    will be on a part with Kite, it is to completly replace it (and take
    back the "Kite" name). Preliminary tests seems to show that, contrary
    to intuition (because built on a more complex/slower grid), it is even
    slightly faster than Kite 8-).

Jean-Paul Chaput 9114766129 Anabatic transient commit 11. Merge Katabatic into Anabatic.
* New: In Anabatic, merge in the Katabatic tool. The merge is not complete
    yet. Only basic capabilities have been moved.
