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.

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.

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 ::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.

Added core2chip support for Phenitec80. This commit degrades the run success rate of ARMv2a to 87% (40 iters). * New: In CRLcore/etc/.../kite.conf, add configuration parameters: katana.termSatReservedlocal katana.termSatthreshold for the new edge capacity computation system. * New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu small I/O pads (supplied in phlib80). Tune various parameters of Anabatic/Katana to increase routing success. * Change: In CRLcore/alliance/ap/ApParser, make Pin external components, so RoutingPad will be build upon in global routing. Do not complain when a I/O pad has a physical instance that did not exists in the netlist. Just create it (appeared in phlib80). When no netlist instance exists in a pad, the pad Cell is still considered as terminal. * New: In Etesian::BloatCells, new profile named "3metals" better suited for two routing metals technologies (i.e. Phenitec). * New: In Anabatic::RawGCellsUnder, new CTOR which take only source & target points instead of a segment. Needed to manage wide segment for which the axis to consider is not that of the segment (one axis for each track it intersect). * New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge reservation computation. * New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing all edges of a fixed amount (hTrackReservedLocal), guess the GCell cluttering from the number of RoutingPads that it contains. For non-saturated GCells, the four edges are decreased by the number of RoutingPads. We use the maximum from the two neigboring GCells. The hTrackReservedLocal parameter is now used only as a *maximum* that the edge reservation can reach. If a GCell is saturated (more than 8 RoutingPads, the saturation is propagated horizontally to 2 neigboring GCells). * Change: In AutoContactTerminal::getNativeConstraintBox(), use a more flexible gauge name matching for terminal vertical extensions correction. Namely, match all "msxlib*" kind of gauges. * Change: In AutoSegment::setAxis(), add the ability to force the axis position, even if it is a non-canonical segment. Maybe needed in the initialisation steo, before the first canonisation is performed. * New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(), to manage coronas for Phenitec designs. To avoid various side effects from segments being too close from the north / east side of the routing area, make those segments fixeds. * Change: In KatanaEngine::annotateGlobalGraph(), the management of wide wires was wrong. The axis to use to find the underlying GCells is the one of the track, not of the segment. This was creating bad edge capacity computation under the power ring of a block and subsequently routing failures. * New: In Kanata::Manipulator, added method reprocessParallels(), not used though, but keep it anyway, might be of use later... * New: In Kanata::Manipulator, added method avoidBlockage() for terminal METAL2 in non-preferred direction, restrict the terminal and turn constraint box at the current position of the perpandicular, so it doesn't create a deadlock in METAL2. * Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break using the whole overlap, try the first atomic overlap. * New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered segment and a blockage, this when to call avoidBlockage()... * New: In Katana::Configuration, management of the new edge computation parameters: katana.termSatReservedlocal katana.termSatthreshold * New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.

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.

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...

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.

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.

Katana manage wide wires, and they can also be symmetric. * New: In Anabatic::AutoContact and the derived classes, manages wide wires.

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.

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.

Upgrade of Katana detailed router to support Arlet 6502. * Change: In Hurricane::SharedName, replace the incremental Id by a hash key. This is to ensure better deterministic properties. Between use cases, additional strings may have to be allocated, shitfing the ids. Even if hash can be duplicated, we should be able to ensure that the absolute order in map table should be preserved. Supplemental strings are inserted in a way that keep the previous order. * Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge" default parameter value ("sxlib"). * Change: In CRL/etc/common/technology.conf, define minimal spacing for symbolic layers too (added for METAL4 only for now). * Change: In CRL::Histogram, extend support to dynamically sized histograms. Add a text pretty print with table and pseudo-curve. * Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the block corona corners so the global router do not draw wire under them. This was creating deadlock for the detailed router. When the abutment has to be computed, directly use Etesian to do it instead of duplicating the computation in the Python plugin. * New: In Etesian, as Coloquinte seems reluctant to evenly spread the standard cells, we trick it by making them bigger during the placement stage. Furthermore, we do not not uniformely increase the size of the cells but create a "bloating profile" based on cell size, cell name or it's density of terminals. Currently only two profiles are defined, "disabled" which does nothing and "nsxlib" targeted on 4 metal layer technologies (aka AMS 350nm, c35b4). * Bug: In Knik::MatrixVertex, load the default routing gauge using the configuration parameter "katabatic.routingGauge" as the default one may not be the first registered one. * New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of the nets terminal numbers. * Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the contact cache when topology is invalidated. In case of multiple invalidations, if the first did not invalidate the cache, later one that may need it where not allowed to do so. The end result was correct nonetheless, but it did generate annoying error messages. * Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation of the contact's depth when delta == 2. * Bug: In Anabatic::Gcell::getCapacity(), was always returning the west edge capacity, even for the westermost GCell, should be the east edge in that case. * New: In Anabatic::AutoSegment, introduce a new measure "distance to terminal". This is the minimal number of segments separating the current one from the nearest RoutingPad. This replace the previous "strong terminal" and "weak terminal" flags. This distance is used by Katana to sort the events, we route the segments *from* the RoutingPads *outward*. The idea being that if we cannot event connect to the RoutingPad, there is no points continuing as thoses segments are the more constraineds. This gives an order close to the simple ascending metals but with better results. * New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable dogleg making on those segments. mainly intended for local segments directly connecteds to RoutingPads (distance == 0). * New: In Anabatic::AutoSegment, more aggressive reducing of segments. Now the only case where a segment cannot be reduced is when it is one horizontal branch in a HTee or a vertical on a VTee. Check if, when not accounted the source & target VIAs are still connex, if so, allow reducing. * New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg mainly to prevent making doglegs twice on a turn contact. This is to limit over-fragmentation. If one dogleg doesn't solve the problem, making a second one will make things worse only... * Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing the component with the *smallest* span instead of the *bigger* one. * New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that no turn go be made inside those GCells. Mainly used underneath a block corona. * New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage GCells with too many terminals. Slacken at least one RoutingPad access when there is more than 8 RoutingPad in the GCell (slacken or change a vertical METAL2 (non-preferred) into a METAL3). * Change: In Anabatic::NetBuilderHV, allow the use of terminal connection in non-preferred direction. That is, vertical METAL2 directly connected to the RoutingPad (then a horizontal METAL2). This alllows for short dogleg without clutering the METAL3 layer (critical for AMS c35b4). Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag. Perform some other tweaking on METAL1 access topologies, to also minimize METAL3 use. * New: In AnabaticEngine::computeNetConstraints(), also compute the distance to RoutingPad for segments. Set the Unbreakable flag, based on the distance and segment length (local, short global or long global). New local function "propagateDistanceFromRp()". * Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder, is modificated so net with a degree superior to 10 are sorted first, whatever their sparsity. This is to work in tandem with GlobalRouting. * New: In Katana::TrackSegmentNonPref, introduce a class to manage segment in non-preferred routing direction. Mostly intended for small METAL2 vertical directly connected to RoutingPad. Modifications to manage this new variant all through Katana. * Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag of the GCell. Do not make bend inside thoses GCells. * Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are routed first and whitout the global routing estimation. There should be few of them so they wont create saturations and we want them as straight as possible. Detour are for long be-points. Set the saerch halo to one GCell in the initial routing stage (before ripup). * Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints() inside NegociateWindow::run(), as segments are inserted into tracks only at that point so we cannot make the computation earlier. * Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to select whether to replace the perpandiculars *after* or *before* the current segment. * Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the segment is fully enclosed inside a global, the longest overlap cost is set to the shortest global hoverhang (before or after). When the cost is for a global, set an infinite cost if the overlapping segment has a RP distance less or equal to 1 (this is an access segment). * Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of the segments extension cap. * New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad. * Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints to any turn connected to the first segment of the RoutingPad so the perpandicular constraints got propagated to the perpandicular segment... * Change: In RoutingEvent, cache the "distance to RP" value. * Change: In RoutingEvent::Key::compare(), sort *first* on distance to RoutingPad, then layer depth. If both distance to RoutingPad is null, then sort on segment length. * Change: In RoutingEvent::_processRepair(), try a repack perpandicular with perpandiculars first (then with perpandicular last, then give up). * Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint when creating the insertion event. * Change: In SegmentFsm::_slackenStrap(), add a step through slacken between minimize and maximum slack (wihch directly end up in unimplemented). * Change: In Session::_addInsertEvent(), add an axis parameter needed when the axis of the segment is not the one of the track (case of wide segments or non-preferred direction). * Bug: In Track::_preDestroy(), bad management of the TrackElement reference count. Destroy the segment only when reaching zero... * Bug: In Track::expandFreeIneterval(), forgotten to manage case when there is a set of overlaping segments at the "end" of the track, the EndIsTrackMax was not set. * Change: In TrackCost::Compare, increase the cost when an overlaping segment is at it's ripup limit. We should try *not* to rip it up if we can. Add a dedicated flag "AtRipupLimit". * Change: In TrackElement, add proxies for isUnbreakable(), new function updateTrackSpan(). * New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is found, make the underlying GCells "GoStraight". * New: In TrackElement::canDogleg(GCell*), check for already done perpandicular dogleg on source/target (reject if so).

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).

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.

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...

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).

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-).

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...

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.
