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-).

Basic support for FreePDK 45 completed. * New: In Commons, inspector support for std::pair<T,U>. * New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non square VIAs. The hole (cut) remains square, but the various metal extensions can now be different in X and Y. The ::getEnclosure() method now takes a flag EnclosureH / EnclosureV. * New: In Hurricane::DbU, inspector support for: std::pair<DbU::Unit,DbU::Unit> std::array<DbU::Unit,3> Must be defined here as DbU do not exists yet in Commons.h * Bug: In Hurricane::Interval::getSize(), when the interval is "full span", do not return the difference between min and max, but directly DbU::Max. (the previous result was -1 !) * New: In CRL Core Python/Technology.py, support for non square VIAs in the configuration files. Applied to FreePDK 45. * New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge is for symbolic layout or not. Exported to Python. * New: In Anabatic::AutoHorizontal::updatePosition(), differentiated computation for soure or target taking account of the VIA extension in the right segment metal (due to non-square VIAs). * Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is UP for HV gauges and DOWN for VH. * New: In Anabatic::AutoSegment::_initialize(), create a cache of the various extension length for each layer (viaToTop, viaToBottom, viaToSame). New implementation of getExtensionCap() using the previous cached extension table. See updatePositions(). New static functions to access the extension cache in the header: getViaTotopCap() ... * Change: In Anabatic::AutoSegment, in various update methods, updateOrient() must always be called *before* updatePositions() as extensions are dependant on source/target. * New: In Anabatic::AutoSegment::getEndAxes() compute the position of the first source and last target position (center/axes) on an *aligned* set of segments. * New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to signal segments that can be put on only one track. Specific case to VH gauge for a M1 vertical terminal with a M2 vertical segment. The M2 is effectively bound to the M1 axis position. * Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global and only one RoutingPad the connexion to the RoutingPad was duplicated. It was valid, but totally stupid. * Bug: In Anabatic::Session::_canonize(), for an aligned segment set, intersect the user constraints from all segments instead of only considering the canonical one. Issue a warning about too tight constraints only for symbolic gauges. It may be correct for the real ones. * New: In Katata::DataNegociate::update(), more accurate computation of the perpandicular free interval. Use segment extension cap calculation. Create a special case for fixed axis segments allowing them to find alternative free interval, try under source and under target as they are likely to be draggable segments. * Change: In Katana::Manipulator::relax(), use the extension cap value to compute the axis of the perpandicular segemnts. * Change: In Katana::Manipulator::moveUp(), now move up the whole set of aligned segments instead of just the canonical one. * Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate TrackMarkers insertions for fixed terminals. * New: In Katana::RoutingEvent::Key::Compare::operator(), segments with fixed axis are processed prior to any others. * New: In Katana::RoutingEventLoop, store segment pointers instead of ids to generate more accurate error messages. * Change: In Katana::RoutingPlane::create(), perform local track assignment only for HV gauges. * Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize" step in the automaton. Mutliple states transitions can occurs in a row if an action fails. * New: In Katana::Session::_toIntervalAxis(), normalize interval bounds so they are on track positions (by shrinking the interval). * Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.
