#include "hurricane/Error.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 7. More Dijkstra bugs correcteds. * Bug: In Anabatic: - Activate the searchArea to limit the area explored by the Dijkstra. Uses the bounding boxes of the vertexes/gcells instead of the ones the RoutingPads. - Always detach contacts from the rings in load(), even if the vertex is already marked as target. - On reaching a target (non-negative connexId), do not forget to update the distance to source. - In Edges locator, added support for side selection (needed by the monotonic feature). * New: In Anabatic: - Hide the atomic Dijkstra methods (made private). - Implementation of the monotonic mode in Dijkstra (for bipoints only). - Added a separate function for distance computation between two vertexes, now take account of the VIAs costs.

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.

Anabatic transient commit 6 "Somatoline, ca marche!". * Bug: In Anabatic: - In Dijktra::load(), do not create Contact while looping over the Net's components (for RoutingPads). - In Dijkstra::propagate(), reset the connexId of reached Vertexes on updating the stamp to avoid using connexId from previous runs. Push the vertexes on the queue while backtracking (with a distance of 0.0). Do not reset the "_from" as we need it in Dijkstra::toWires() to know how were the routing is. - In Edge::getDistance(), convert to float more early so the normalisation do not always end up in zero. - In GCell::_add(), when the axis of the new edge is equal to one already on the given side, adds it *after* the existing edge and not before. (to be coherent with the way GCells are split in two) - In GCell::hcut() and GCell::vcut(), create an Edge if is equal to X/Y Max, *but* the new chunk is flat. The new chunk is then expected to expand "below". - In GraphicsAnabaticEngine::drawGCell(), display the id of the GCell in a small box at the center of it's bounding box. Nothing displayed for flat GCells, to avoid cluttering.

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.

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.

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.

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).

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).

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 6 "Somatoline, ca marche!". * Bug: In Anabatic: - In Dijktra::load(), do not create Contact while looping over the Net's components (for RoutingPads). - In Dijkstra::propagate(), reset the connexId of reached Vertexes on updating the stamp to avoid using connexId from previous runs. Push the vertexes on the queue while backtracking (with a distance of 0.0). Do not reset the "_from" as we need it in Dijkstra::toWires() to know how were the routing is. - In Edge::getDistance(), convert to float more early so the normalisation do not always end up in zero. - In GCell::_add(), when the axis of the new edge is equal to one already on the given side, adds it *after* the existing edge and not before. (to be coherent with the way GCells are split in two) - In GCell::hcut() and GCell::vcut(), create an Edge if is equal to X/Y Max, *but* the new chunk is flat. The new chunk is then expected to expand "below". - In GraphicsAnabaticEngine::drawGCell(), display the id of the GCell in a small box at the center of it's bounding box. Nothing displayed for flat GCells, to avoid cluttering.

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.

Used for analog mode. * Change: In NetRoutingState, added a flag for analog mode. Use uint32_t for the flags type. * New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

Corrections in the Dijkstra global routing (ripup) mechanism. * Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors belonging to the same net) was miscalculated. This was leading, in the materialize step to some feed-through vertexes not being broken. Leading in turn to incomplete transformation of the detailed routing. Also in _trackback(), the degree of the first vertex we were backtracking from was not incremented. * Bug: In Anabatic::Dijkstra::materialize(), systematically use GCell::breakGoThrough() on both source and target. This is needed when we are in the ripup phase as both source and target can be go-through. This was also leading to incomplete detailed routing transformation. * Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead of thoses exeeding the global length threshold. This way we are sure to desaturate an edge. Needs to be further calibrated. * Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL. Return existing gcontact if any. Break if it is a go-through and create a new gcontact in last resort. Maybe rename this function. * New: In Anabatic::Configuration, new parameters: - anabatic.edgeHScaling, to adjust the length of the horizontal edges relative to the vertical ones (this is a ratio). - anabatic.globalIterations, set the maximum number of ripup passes of the global router. * New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling and anabatic.globalIterations. * New: In Katana::GlobalRoute::DigitalDistance, take into account the new edgeHScaling factor. Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

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.

DbU::Unit Dijkstra::_distance ( const Vertex* current, const Vertex* vneighbour, const Edge* e )
Anabatic transient commit 7. More Dijkstra bugs correcteds. * Bug: In Anabatic: - Activate the searchArea to limit the area explored by the Dijkstra. Uses the bounding boxes of the vertexes/gcells instead of the ones the RoutingPads. - Always detach contacts from the rings in load(), even if the vertex is already marked as target. - On reaching a target (non-negative connexId), do not forget to update the distance to source. - In Edges locator, added support for side selection (needed by the monotonic feature). * New: In Anabatic: - Hide the atomic Dijkstra methods (made private). - Implementation of the monotonic mode in Dijkstra (for bipoints only). - Added a separate function for distance computation between two vertexes, now take account of the VIAs costs.

Correct multiple backtrack from same connex components (pathological). * Bug: In Dijkstra::_materialize(), in some special case a connex component can is reached by two (or more) vertexes. But of course it will be connected only through one, all others must be discarteds. The right one will have it's connex id set, all the others will stay to -1. So stop any backtrack when the first neighbor of a starting point has it's connex id *not* set.

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).

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.

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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.

Push the vertexes on the queue while backtracking (with a distance of 0.0). Do not reset the "_from" as we need it in Dijkstra::toWires() to know how were the routing is. - In Edge::getDistance(), convert to float more early so the normalisation do not always end up in zero. - In GCell::_add(), when the axis of the new edge is equal to one already on the given side, adds it *after* the existing edge and not before. (to be coherent with the way GCells are split in two) - In GCell::hcut() and GCell::vcut(), create an Edge if is equal to X/Y Max, *but* the new chunk is flat.

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.

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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()".

Corrections in the Dijkstra global routing (ripup) mechanism. * Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors belonging to the same net) was miscalculated. This was leading, in the materialize step to some feed-through vertexes not being broken. Leading in turn to incomplete transformation of the detailed routing. Also in _trackback(), the degree of the first vertex we were backtracking from was not incremented. * Bug: In Anabatic::Dijkstra::materialize(), systematically use GCell::breakGoThrough() on both source and target. This is needed when we are in the ripup phase as both source and target can be go-through. This was also leading to incomplete detailed routing transformation. * Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead of thoses exeeding the global length threshold. This way we are sure to desaturate an edge. Needs to be further calibrated. * Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL. Return existing gcontact if any. Break if it is a go-through and create a new gcontact in last resort. Maybe rename this function. * New: In Anabatic::Configuration, new parameters: - anabatic.edgeHScaling, to adjust the length of the horizontal edges relative to the vertical ones (this is a ratio). - anabatic.globalIterations, set the maximum number of ripup passes of the global router. * New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling and anabatic.globalIterations. * New: In Katana::GlobalRoute::DigitalDistance, take into account the new edgeHScaling factor. Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

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.

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

_searchArea.inflate( _searchAreaHalo );
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()".

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.

Uses the bounding boxes of the vertexes/gcells instead of the ones the RoutingPads. - Always detach contacts from the rings in load(), even if the vertex is already marked as target. - On reaching a target (non-negative connexId), do not forget to update the distance to source. - In Edges locator, added support for side selection (needed by the monotonic feature). * New: In Anabatic: - Hide the atomic Dijkstra methods (made private). - Implementation of the monotonic mode in Dijkstra (for bipoints only). - Added a separate function for distance computation between two vertexes, now take account of the VIAs costs.

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.

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.

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()".

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()".

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.

/*if ( (distance == vneighbor->getDistance())
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.

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.

This avoids overload resolution problems with arithmetical overload of the operators. The BaseFlags/Flags types are now completly "isolated" from the uint64_t, it has the advantage of showing where unwanted previous implicit conversions where occuring. * Change: In Katana::Constants, Flags values are now of BaseFlags type instead of uint64_t. * Change: In Anabatic::Dijkstra, lots of log cleanup. * Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible to allow to substract the topmost and rightmost track for axis span computation in AutoSegment::computeOptimal(). Used for analog mode. * Change: In NetRoutingState, added a flag for analog mode. Use uint32_t for the flags type. * New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

Anabatic transient commit 6 "Somatoline, ca marche!". * Bug: In Anabatic: - In Dijktra::load(), do not create Contact while looping over the Net's components (for RoutingPads). - In Dijkstra::propagate(), reset the connexId of reached Vertexes on updating the stamp to avoid using connexId from previous runs. Push the vertexes on the queue while backtracking (with a distance of 0.0). Do not reset the "_from" as we need it in Dijkstra::toWires() to know how were the routing is. - In Edge::getDistance(), convert to float more early so the normalisation do not always end up in zero. - In GCell::_add(), when the axis of the new edge is equal to one already on the given side, adds it *after* the existing edge and not before. (to be coherent with the way GCells are split in two) - In GCell::hcut() and GCell::vcut(), create an Edge if is equal to X/Y Max, *but* the new chunk is flat. The new chunk is then expected to expand "below". - In GraphicsAnabaticEngine::drawGCell(), display the id of the GCell in a small box at the center of it's bounding box. Nothing displayed for flat GCells, to avoid cluttering.

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.

// We did reach another target (different <connexId>).
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.

Anabatic transient commit 9. Dijkstra::_traceback() replaces _toWires(). * Change: In Anabatic: - In Dijkstra, replace _toWires() by _trackback() which is called immediatly on reaching a target. - In Constants & GCell, added flags for typing the GCells. We now have: * DeviceGCell, for analogic devices. * ChannelGCell, for resizable routing channels. * StrutGCell, for fixed spaces in analog designs. * MatrixGCell, for square tile in digital designs.

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.

In Dijkstra.cpp/.h: - GlobalRouting takes into account self symmetries and symmetries in pair of nets according to an axis. Self symmetries are symmetries considering one net symmetric to an axis. During the materialize step, they are routed symmetrically according to the axis. Symmetries in pair of nets follow the same principle but with 2 nets. In LocalGlobalRouting.cpp: - Minor bug fixed - Verbose commented in NetRoutingProperty.cpp/.h: - Some flags methods methods added
2017-03-08 10:49:23 -06:00
Added analog type on segment NetRoutingProperty. * New: In Anabatic_AutoSegments collection, added a Flag to the constructors to allow different behavior between digital and analog modes. For "Aligneds" and "Perpandiculars" collections, now manage a new Flag WithDoglegs to follow aligned globals through local doglegs (for analog nets). Adjust the log level of collections to 144 (formerly 145). * New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are part of an analog net. Note that with this flag, we reach the 32 bits limit... * Change: In Anabatic::Constants, Flags are now declared as BaseFlags objects and *not* uint64_t. This avoids overload resolution problems with arithmetical overload of the operators. The BaseFlags/Flags types are now completly "isolated" from the uint64_t, it has the advantage of showing where unwanted previous implicit conversions where occuring. * Change: In Katana::Constants, Flags values are now of BaseFlags type instead of uint64_t. * Change: In Anabatic::Dijkstra, lots of log cleanup. * Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible to allow to substract the topmost and rightmost track for axis span computation in AutoSegment::computeOptimal(). Used for analog mode. * Change: In NetRoutingState, added a flag for analog mode. Use uint32_t for the flags type. * New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

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.

Dijkstra::_traceback() replaces _toWires(). * Change: In Anabatic: - In Dijkstra, replace _toWires() by _trackback() which is called immediatly on reaching a target. - In Constants & GCell, added flags for typing the GCells. We now have: * DeviceGCell, for analogic devices. * ChannelGCell, for resizable routing channels. * StrutGCell, for fixed spaces in analog designs. * MatrixGCell, for square tile in digital designs.

{
cdebug_log(112,1) << "Dijkstra::_traceback() " << _net << " branchId:" << _sources.size() << endl;
Corrections in the Dijkstra global routing (ripup) mechanism. * Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors belonging to the same net) was miscalculated. This was leading, in the materialize step to some feed-through vertexes not being broken. Leading in turn to incomplete transformation of the detailed routing. Also in _trackback(), the degree of the first vertex we were backtracking from was not incremented. * Bug: In Anabatic::Dijkstra::materialize(), systematically use GCell::breakGoThrough() on both source and target. This is needed when we are in the ripup phase as both source and target can be go-through. This was also leading to incomplete detailed routing transformation. * Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead of thoses exeeding the global length threshold. This way we are sure to desaturate an edge. Needs to be further calibrated. * Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL. Return existing gcontact if any. Break if it is a go-through and create a new gcontact in last resort. Maybe rename this function. * New: In Anabatic::Configuration, new parameters: - anabatic.edgeHScaling, to adjust the length of the horizontal edges relative to the vertical ones (this is a ratio). - anabatic.globalIterations, set the maximum number of ripup passes of the global router. * New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling and anabatic.globalIterations. * New: In Katana::GlobalRoute::DigitalDistance, take into account the new edgeHScaling factor. Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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.

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()".

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 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

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 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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()".

Correct multiple backtrack from same connex components (pathological). * Bug: In Dijkstra::_materialize(), in some special case a connex component can is reached by two (or more) vertexes. But of course it will be connected only through one, all others must be discarteds. The right one will have it's connex id set, all the others will stay to -1.

Corrections in the Dijkstra global routing (ripup) mechanism. * Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors belonging to the same net) was miscalculated. This was leading, in the materialize step to some feed-through vertexes not being broken. Leading in turn to incomplete transformation of the detailed routing. Also in _trackback(), the degree of the first vertex we were backtracking from was not incremented. * Bug: In Anabatic::Dijkstra::materialize(), systematically use GCell::breakGoThrough() on both source and target. This is needed when we are in the ripup phase as both source and target can be go-through. This was also leading to incomplete detailed routing transformation. * Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead of thoses exeeding the global length threshold. This way we are sure to desaturate an edge. Needs to be further calibrated. * Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL. Return existing gcontact if any. Break if it is a go-through and create a new gcontact in last resort. Maybe rename this function. * New: In Anabatic::Configuration, new parameters: - anabatic.edgeHScaling, to adjust the length of the horizontal edges relative to the vertical ones (this is a ratio). - anabatic.globalIterations, set the maximum number of ripup passes of the global router. * New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling and anabatic.globalIterations. * New: In Katana::GlobalRoute::DigitalDistance, take into account the new edgeHScaling factor. Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

Correct multiple backtrack from same connex components (pathological). * Bug: In Dijkstra::_materialize(), in some special case a connex component can is reached by two (or more) vertexes. But of course it will be connected only through one, all others must be discarteds. The right one will have it's connex id set, all the others will stay to -1. So stop any backtrack when the first neighbor of a starting point has it's connex id *not* set.

Corrections in the Dijkstra global routing (ripup) mechanism. * Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors belonging to the same net) was miscalculated. This was leading, in the materialize step to some feed-through vertexes not being broken. Leading in turn to incomplete transformation of the detailed routing. Also in _trackback(), the degree of the first vertex we were backtracking from was not incremented. * Bug: In Anabatic::Dijkstra::materialize(), systematically use GCell::breakGoThrough() on both source and target. This is needed when we are in the ripup phase as both source and target can be go-through. This was also leading to incomplete detailed routing transformation. * Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead of thoses exeeding the global length threshold. This way we are sure to desaturate an edge. Needs to be further calibrated. * Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL. Return existing gcontact if any. Break if it is a go-through and create a new gcontact in last resort. Maybe rename this function. * New: In Anabatic::Configuration, new parameters: - anabatic.edgeHScaling, to adjust the length of the horizontal edges relative to the vertical ones (this is a ratio). - anabatic.globalIterations, set the maximum number of ripup passes of the global router. * New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling and anabatic.globalIterations. * New: In Katana::GlobalRoute::DigitalDistance, take into account the new edgeHScaling factor. Must be used when the capacity of V-edges differs greatly for H-edges (case of AMS 350nm c35b4 for instance). * Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is computed for an edge length of "1". Must be multiplicated by the current edge length to have any measurable effect. This bug is finally explaining why the ripup was producing the same solutions over and over, the historical cost was negligible!

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()".

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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.

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.

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()".

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 9. Dijkstra::_traceback() replaces _toWires(). * Change: In Anabatic: - In Dijkstra, replace _toWires() by _trackback() which is called immediatly on reaching a target. - In Constants & GCell, added flags for typing the GCells. We now have: * DeviceGCell, for analogic devices. * ChannelGCell, for resizable routing channels. * StrutGCell, for fixed spaces in analog designs. * MatrixGCell, for square tile in digital designs.

Added analog type on segment NetRoutingProperty. * New: In Anabatic_AutoSegments collection, added a Flag to the constructors to allow different behavior between digital and analog modes. For "Aligneds" and "Perpandiculars" collections, now manage a new Flag WithDoglegs to follow aligned globals through local doglegs (for analog nets). Adjust the log level of collections to 144 (formerly 145). * New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are part of an analog net. Note that with this flag, we reach the 32 bits limit... * Change: In Anabatic::Constants, Flags are now declared as BaseFlags objects and *not* uint64_t. This avoids overload resolution problems with arithmetical overload of the operators. The BaseFlags/Flags types are now completly "isolated" from the uint64_t, it has the advantage of showing where unwanted previous implicit conversions where occuring. * Change: In Katana::Constants, Flags values are now of BaseFlags type instead of uint64_t. * Change: In Anabatic::Dijkstra, lots of log cleanup. * Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible to allow to substract the topmost and rightmost track for axis span computation in AutoSegment::computeOptimal(). Used for analog mode. * Change: In NetRoutingState, added a flag for analog mode. Use uint32_t for the flags type. * New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

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.

Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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().

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.

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().

Anabatic transient commit 14. Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell. It was memory-consuming and algorithmically inefficient. Now there is only one straight wire. As a consequence, Edges now store the list of all segments going through them. That way we do not need to load a Net into Dijkstra before riping up some of it's segment. The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

The ripup mechanims can now be implemented right at AnabaticEngine level, without dependencies over Dijkstra. Note that long wires are automatically broken in two if we need to attach a new branch on it (breakAt()). And fused back into one if a branch is removed (unify()).

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.

Change model for long wires. * Change: In Anabatic: - Long wires, going straight accross multiple GCells were splitted into a long sequence of segment+contact, one for each gone-through GCell.

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 analog type on segment NetRoutingProperty. * New: In Anabatic_AutoSegments collection, added a Flag to the constructors to allow different behavior between digital and analog modes. For "Aligneds" and "Perpandiculars" collections, now manage a new Flag WithDoglegs to follow aligned globals through local doglegs (for analog nets). Adjust the log level of collections to 144 (formerly 145). * New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are part of an analog net. Note that with this flag, we reach the 32 bits limit... * Change: In Anabatic::Constants, Flags are now declared as BaseFlags objects and *not* uint64_t. This avoids overload resolution problems with arithmetical overload of the operators. The BaseFlags/Flags types are now completly "isolated" from the uint64_t, it has the advantage of showing where unwanted previous implicit conversions where occuring. * Change: In Katana::Constants, Flags values are now of BaseFlags type instead of uint64_t. * Change: In Anabatic::Dijkstra, lots of log cleanup. * Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible to allow to substract the topmost and rightmost track for axis span computation in AutoSegment::computeOptimal(). Used for analog mode. * Change: In NetRoutingState, added a flag for analog mode. Use uint32_t for the flags type. * New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.

//cerr << "e: " << e << endl;
Dijkstra and Net can manage different wire width. in Dijkstra.cpp/.h, Edge.cpp/.h, GCell.cpp/.h: *Change: GlobalRouting wires can have different wires' width. One Net's wires has one width only. in NetRoutingProperty.cpp/.h, PyNetRoutingProperty.cpp/.h: *New: A wire width parameter is added. It can be set through python script.

In Dijkstra.cpp/.h: - GlobalRouting takes into account self symmetries and symmetries in pair of nets according to an axis. Self symmetries are symmetries considering one net symmetric to an axis. During the materialize step, they are routed symmetrically according to the axis. Symmetries in pair of nets follow the same principle but with 2 nets. In LocalGlobalRouting.cpp: - Minor bug fixed - Verbose commented in NetRoutingProperty.cpp/.h: - Some flags methods methods added
