Jean-Paul Chaput 094cb8a132 Improved handling of short nets (fully included in one GCell).
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.

* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
    that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
    output of zero and one cell, also skip the blockage net (as well as
    automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
    segment is part of a short net (fully included in *one* GCell).
      Also add accessor/mutators for the _analogMode flag (was it ever
    used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
    vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
    they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
    "short net" and "analog mode" creation flags between two different
    nets.
* New: In Katana::Configuration, added dedicated ripup for short net
    segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
    is dogleg that are always kept in same metal because they connect
    neighboring perpandicular tracks. Not finished neither activated
    yet.
* New: In Katana::TreckElement and derived, export the the *short net*
    support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
    successfully inserted, re-process any perpandicular that is in
    repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
    of issuing false check messages.

Jean-Paul Chaput 95aba574a5 Happy New Year 2018 ! Update license years... 2018-01-06 17:55:44 +01:00
Jean-Paul Chaput e12e45e495 Rename SymmetricStage into PairSymmetrics, plus small cleanup. 2017-05-26 13:32:30 +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.

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 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-).
