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-).

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).

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.

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).

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.

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.

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-).

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.

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...

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).

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).

// Predicates.
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).

(the previous result was -1 !) * New: In CRL Core Python/Technology.py, support for non square VIAs in the configuration files.

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.

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-).

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).

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).

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).

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.

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).

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.

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).

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-).

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).

void TrackSegment::setTrack ( Track* track )
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.

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).

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.

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-).

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).

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.

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).

void TrackSegment::reschedule ( uint32_t level )
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-).

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.

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).

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.

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.

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()".

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-).

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).

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).

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.

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-).
