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.

Anabatic transient commit 10. Ripup & reroute support in Dijsktra. * New: In Anabatic: - In AnabaticEngine, keep track of overflowed edges. - In AnabaticEngine, getNetsFromedge() to lookup all nets going through an Edge. - In Configuration, read the Kite "reserved local" parameter to decrease the Edge capacity (it's a guessing of the cost of the local routing). - In Edge, add an attribute to know if there is an associated segment of the current net (set by Dijkstra::_traceback()). Transparently manage the overflowed edges. - In GCell_Edges, correct a filtering bug when not all sides are selecteds. - New GCell::getEdgeTo() to find the edge between two adjacent GCells. - New GCell::unrefContact() to automatically removes global contacts no longer used by any global segments (used during the ripup step). - In Dijkstra::load(), now able to "reload" and already partially or completly routed net (look for Contact of "gcontact" layer and their attached segments). - In Dijkstra, keep the last net loaded until the next one is. Put the cleanup operations in an isolated function "_cleanup()". - In Dijkstra::_selectFirstsource() and run(), load first source component made of multiple vertexes. - In Dijkstra::_trackback(), link the Net segments to the Edges. - New Dijkstra::ripup(), Dijkstra::_propagateRipup() to perform the ripup of one edge of a Net (must be loaded in Dijkstra first). Dijkstra::_tagConnecteds() setup the connexId of a set of Vertexes - that are connecteds through edges *with* segments. - In GraphicAnabaticengine & GlobalRoute.cpp, embryo of a global routing tool with ripup & reroute.

#include "anabatic/AutoContactTerminal.h"
#include "anabatic/NetBuilderM2.h"
#include "anabatic/NetBuilderHV.h"
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.

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-).

Capacity managment by layer in Edges & GCells (plus fixes). * New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities of an edge by layer. This needed now because with real technologies layers capacities differs (unlike with symbolic technologies). This object is separated to be shared between Edges with identical characteristics (direction+interval). Deletion is automatic and done through refcounting. All the already allocateds EdgeCapacity are kept into a set in the AnabaticEngine (key is (direction,interval)). * New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity object. The total capacity can be annotated (i.e. decreased). EdgeCapacity attribute is created during the materialize() call. The capacities are computed at this time. The incCapacity() function is renamed in reserveCapacity(). * New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut to store the shared EdgeCapacity. Lookup/Creation of an EdgeCapacity is done through _createCapacity(). * Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges). * Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity(). This modification did expose a bug in the density calculation : per depth density where divided by the complete density instead of the density's depth. This was leading to greatly underestimated densities. Thoses underestimations where preventing Dijkstra and layer assignement to manage congestion correctly (in fact, it was acting as if there never was congestion). Also avoid a divide by zero (thus -NAN showing in densities). * Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more accurate forceEdgesCapacities(). Note for Eric: only the first Edge on each side has it's capacity forced. What if there's more than one Edge ?

Anabatic transient commit 8. More Dijkstra bugs correcteds. * Bug: In Anabatic: - In _propagate(), on reaching a target, forgot to remove it from the queue before pushing it back with the new distance. It also simplificate the core algorithm as target as treated normal nodes. * New: In Anabatic: - Update cdebug to use the fastest macro version. - More readable drawings of GCells and Edges. - Added timer support. - The distance is now computed in DbU::Unit (aka long) and not in normalized float. - The distance function is now a callback (std::function<>) that can be changed (a default is provided at initialization). - New concept of branch in the agglomerated connex component. Each trace back part create a "branch" (tagged with a "branchId"). When a node is reached with the same distance, but from two different branches, choose the the branch that was lastly created. This create a slightly different tree which grows outward from the newest branches. - Makes the horizontal edges *slightly* longer than the vertical ones to skew the tree to use vertical edges, as it is usually less congested than the horiontal one (due to metal1 cell terminals). It is also my understanding that it is useful to reduce the number of vias, whithout introducing a via cost. * New: In Bootstrap: - Script sprof.py to perform sprof & demangle libraries execution profile. * ToDo: In Anabatic: - Corner optimization. Sometimes when two corners are possible, the wrong one is choosen. That is, one of it's edge cannot be used for further grow of the tree.

It also simplificate the core algorithm as target as treated normal nodes. * New: In Anabatic: - Update cdebug to use the fastest macro version. - More readable drawings of GCells and Edges. - Added timer support. - The distance is now computed in DbU::Unit (aka long) and not in normalized float. - The distance function is now a callback (std::function<>) that can be changed (a default is provided at initialization). - New concept of branch in the agglomerated connex component. Each trace back part create a "branch" (tagged with a "branchId"). When a node is reached with the same distance, but from two different branches, choose the the branch that was lastly created. This create a slightly different tree which grows outward from the newest branches. - Makes the horizontal edges *slightly* longer than the vertical ones to skew the tree to use vertical edges, as it is usually less congested than the horiontal one (due to metal1 cell terminals). It is also my understanding that it is useful to reduce the number of vias, whithout introducing a via cost. * New: In Bootstrap: - Script sprof.py to perform sprof & demangle libraries execution profile. * ToDo: In Anabatic: - Corner optimization. Sometimes when two corners are possible, the wrong one is choosen. That is, one of it's edge cannot be used for further grow of the tree.

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-).

Added support for 2-Metal block routing in Anabatic & Katana. * New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary workaround for a Hurricane problems. When an instance is moved, the RoutingPads that use it must be moved accordingly, but they are not invalidated so they stay in the wrong QuadTree. 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()".

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.

Anabatic transient commit 10. Ripup & reroute support in Dijsktra. * New: In Anabatic: - In AnabaticEngine, keep track of overflowed edges. - In AnabaticEngine, getNetsFromedge() to lookup all nets going through an Edge. - In Configuration, read the Kite "reserved local" parameter to decrease the Edge capacity (it's a guessing of the cost of the local routing). - In Edge, add an attribute to know if there is an associated segment of the current net (set by Dijkstra::_traceback()). Transparently manage the overflowed edges. - In GCell_Edges, correct a filtering bug when not all sides are selecteds. - New GCell::getEdgeTo() to find the edge between two adjacent GCells. - New GCell::unrefContact() to automatically removes global contacts no longer used by any global segments (used during the ripup step). - In Dijkstra::load(), now able to "reload" and already partially or completly routed net (look for Contact of "gcontact" layer and their attached segments). - In Dijkstra, keep the last net loaded until the next one is. Put the cleanup operations in an isolated function "_cleanup()". - In Dijkstra::_selectFirstsource() and run(), load first source component made of multiple vertexes. - In Dijkstra::_trackback(), link the Net segments to the Edges. - New Dijkstra::ripup(), Dijkstra::_propagateRipup() to perform the ripup of one edge of a Net (must be loaded in Dijkstra first). Dijkstra::_tagConnecteds() setup the connexId of a set of Vertexes - that are connecteds through edges *with* segments. - In GraphicAnabaticengine & GlobalRoute.cpp, embryo of a global routing tool with ripup & reroute.

Capacity managment by layer in Edges & GCells (plus fixes). * New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities of an edge by layer. This needed now because with real technologies layers capacities differs (unlike with symbolic technologies). This object is separated to be shared between Edges with identical characteristics (direction+interval). Deletion is automatic and done through refcounting. All the already allocateds EdgeCapacity are kept into a set in the AnabaticEngine (key is (direction,interval)). * New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity object. The total capacity can be annotated (i.e. decreased). EdgeCapacity attribute is created during the materialize() call. The capacities are computed at this time. The incCapacity() function is renamed in reserveCapacity(). * New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut to store the shared EdgeCapacity. Lookup/Creation of an EdgeCapacity is done through _createCapacity(). * Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges). * Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity(). This modification did expose a bug in the density calculation : per depth density where divided by the complete density instead of the density's depth. This was leading to greatly underestimated densities. Thoses underestimations where preventing Dijkstra and layer assignement to manage congestion correctly (in fact, it was acting as if there never was congestion). Also avoid a divide by zero (thus -NAN showing in densities). * Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more accurate forceEdgesCapacities(). Note for Eric: only the first Edge on each side has it's capacity forced. What if there's more than one Edge ?

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.

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.

Added support for 2-Metal block routing in Anabatic & Katana. * New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary workaround for a Hurricane problems. When an instance is moved, the RoutingPads that use it must be moved accordingly, but they are not invalidated so they stay in the wrong QuadTree. 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()".

Capacity managment by layer in Edges & GCells (plus fixes). * New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities of an edge by layer. This needed now because with real technologies layers capacities differs (unlike with symbolic technologies). This object is separated to be shared between Edges with identical characteristics (direction+interval). Deletion is automatic and done through refcounting. All the already allocateds EdgeCapacity are kept into a set in the AnabaticEngine (key is (direction,interval)). * New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity object. The total capacity can be annotated (i.e. decreased). EdgeCapacity attribute is created during the materialize() call. The capacities are computed at this time. The incCapacity() function is renamed in reserveCapacity(). * New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut to store the shared EdgeCapacity. Lookup/Creation of an EdgeCapacity is done through _createCapacity(). * Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges). * Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity(). This modification did expose a bug in the density calculation : per depth density where divided by the complete density instead of the density's depth. This was leading to greatly underestimated densities. Thoses underestimations where preventing Dijkstra and layer assignement to manage congestion correctly (in fact, it was acting as if there never was congestion). Also avoid a divide by zero (thus -NAN showing in densities). * Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more accurate forceEdgesCapacities(). Note for Eric: only the first Edge on each side has it's capacity forced. What if there's more than one Edge ?

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-).

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.
