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.

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 .

* ./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).
