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.

First working recursive place & route (Libre-SOC ALU16 benchmark). * New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one without instances. Now it can be software defined with the "FlattenLeaf" state. If it is flagged "flatten leaf" is will be considered as a leaf by the trans-hierarchical walkthrough. This flag is also set for Cells in the Alliance CATAL. * New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a test to prune leaf cells. * Bug: In Hurricane::getComponentOccurrences(), when calling the locator constructor, the "withLeafCells" argument was forgotten and was getting the value of "doExtraction" (wich, fortunately, was the same). * Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(), prune the leaf cells instead of the terminal ones. * Change: In Hurricane::HypreNet_ComponentOccurrences::progress(), prune the leaf cells instead of the terminal ones. * New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into account or ignore the "FlattenLeaf" flag when doing trans- hierarchical walkthrough. Not sure if it shouldn't be systematic. * New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf" mode for all walkthough. So we can stop at already placed sub-blocks. * Bug: In Etesian::toColoquinte(), when placed sub-block where present, the number of instances was under estimated, so the instance array was oversized and the end went unitialized. So we were getting all kind of strange behavior from Coloquinte... Now throw an exception if the number of instances differs from the computed size. * Bug: In Etesian::toColoquinte(), as for the instance array, now correctly compute the size with the ecluded nets (supplies, clocks). * Bug: In Etesian::resetPlacement(), event if the Cell is unplaced, go through the instance list to remove the potential feed cells. The netlist is written back after placement *with* the feed cells added. So, when loading again, they where cluttering the netlist and giving feed redefintions warning. They also generated erratic behaviors. * New: In Anabatic::NetBuilderHV, added configurations for: * 1G_1M1_1PinM3 * 1G_xM1_1PinM2 * 2G_xM1_1PinM2 * doRp_AccessNorthPin * New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell. * Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South global routing configuration was forgotten (only East/West). * Bug: In Katana::TrackFixedSegment, the blockage net was a static variable initialized at the first run. So we were getting stuck with the blockage net of the first cell to be routed. Of course, it did show only when Katana was run multiple times in the same process.

Enable the display of GCells as a density map (and not boundaries). * Bug: In Anabatic::RawGCellsUnder, *again*, the north and east borders of the whole area *are* includeds (shut up disgraceful warning). * New: In Anabatic::GCell, add a display mode to select between boundary display (for analogic) and density display (for numeric). * Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot be desatured when the vector or overloaded Edges is empty. (one less disgraceful warning) * New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells in density mode. Use the fire scale and the MaxDensity mode. Setup the GCell drawing mode in GraphicKatanaEngine::initGCell(). * Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds for showing the Edge and its label. * New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic parameters. Adjust the showing threshold for GCells in "display.conf" so when the zoom level is low, we still can see the density map.

// Class : "Anabatic::Configuration".
Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

Configuration::Configuration ( const CellGauge* cg, const RoutingGauge* rg )
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!

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

Second version of the antenna effect protection. * Change: In EtesianEngine::globalPlace(), disable the call to antennaProtect(). First reason is that, after all, Coloquinte do not handle so well the resizing of the cells "on the fly", it overspill the boundaries sometimes. Second reason is that as we cannot know the routing tree at this stage, we will not be able to choose the correct points for diode insertions. We only have a Steiner tree wich may not be the same as a density driven Dijkstra. * Change: In Etesian::Area, the Occurrence to the Instances where not stored in a uniform way. Some where starting from the placed sub-block, some where starting from the top level (corona), making their processing (and remembering it) tricky. Now, they are all expressed from the top cell (corona). The coordinate system is now systematically the one of the top block (*not* the block). Create various overloaded functions EtesianEngine::toCell() and EtesianEngine::toBlock() to ease Occurrence & coordinate translations. * New: In Etesian::Slice::createDiodeUnder(), add a X position hint. Search is done by going through the whole slice range and minimizing the distance to the hint. If it starts to be too slow, we may optimize. * Bug: In EtesianEngine::toColoquinte(), the placement of the top level external pins was not taken into account (this at last explain their weird positioning). * New: AnabaticEngine::antennaProtect(), new algorithm to avoid antenna effect. This step must be done *after* global routing and *before* detailed routing. This way we have access to the real routing and can mend it (along with the netlist) to insert diodes at the rigth points. From the global routing we build clusters (DiodeCluster) of RoutingPads connected through a set of wire whose total length is below the antenna effect threshold. Long wires connecting the clusters are also tagged because we need to put a diode between them and the first RoutingPad of the cluster. This is to avoid a long METAL2 wire connecting to the RoutingPad before the diode is connected through METAL3 (in case of misalignment). This protection is not even enough. For *very long* wires, we needs to put *more* than one diode (this is to be implemented).

Enable the display of GCells as a density map (and not boundaries). * Bug: In Anabatic::RawGCellsUnder, *again*, the north and east borders of the whole area *are* includeds (shut up disgraceful warning). * New: In Anabatic::GCell, add a display mode to select between boundary display (for analogic) and density display (for numeric). * Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot be desatured when the vector or overloaded Edges is empty. (one less disgraceful warning) * New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells in density mode. Use the fire scale and the MaxDensity mode. Setup the GCell drawing mode in GraphicKatanaEngine::initGCell(). * Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds for showing the Edge and its label. * New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic parameters. Adjust the showing threshold for GCells in "display.conf" so when the zoom level is low, we still can see the density map.

This speeds up the Cell::getNet() method by suppressing one copy construction of a Name, which are costly after all... Should review the whole code to use "const Name&" everywhere it is possible. * Change: In Hurricane::Entity & Hurricane::DBo, displace the unique identifier from Entity to DBo (move up to the base class).This to allow us to build deterministic map of DBo requireds in UpdateSession (which is built upon a SharedProperty). WARNING: This break the JSON database exportation support, do not use it until fixed/rewritten. * Change: In Hurricane::Layer, add an attribute to know if a layer is associated to a blockage. Modificate accordingly PyLayer and BasicLayer. * Change: In Hurricane::SharedProperty, the set of owners (DBo*) is now stored in a std::set sorted on the objects Ids, instead of a simple vector. The linera search time through the std::vector was starting to show (ISPD05 bigblue1). * Bug: In Isobar::PyInstance, make full contructor signature (5 arguments) conform to the C++ one.

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()".

_allowedDepth = rg->getDepth()-1;
Support for mixing real pads & symbolic core. Wrapper around s2r. * Change: In Hurricane::Error constructors disable the backtrace generation. (*very* slow). * Change: In Hurricane::Library::getHierarchicalname(), more compact naming. Remove the name of the root library. * New: In Hurricane::Net, new type "FUSED", for component with no net. More efficient than having one net for each. * Change: In CellViewer, BreakpointWidget, use Angry Birds icons. * Change: In CellWidget::State, use the hierarchical name (cached) as key to the state. This allow to load two cells with the same name but from different libraries in the widget history. * Change: In PyGraphics, export "isEnabled()" and "isHighDpi()" functions. * Change: In CRL/etc/symbolic/cmos/plugin.conf, and CRL/etc/common/plugin.conf use the physical dimensions converters. * Change: In CRL/etc/symbolic/cmos/technology.conf, make the GDS layer table coherent with the default Alliance cmos.rds. * New: CRL/python/helpers/io.py, put ErrorMessage new implementation here, along with a new ErrorWidget written in PyQt4. It seems finally that PyQt4 can be used alongside Coriolis Qt widgets. New ErrorMessage.catch() static function to manage all exceptions in except clauses. * Change: In CRL/python/helpers/, no longer use ErrorMessage.wrapPrint(), directly print it. Rewrite the utilities to display Python stack traces "textStacktrace()" and "showStacktrace()". * Change: In CRL::AllianceFramework, shorten the names of the libraries. * Change: In CRL::ApParser & CRL::ApDriver, more accurate translation between Alliance connectors (C record) and Hurricane::Pin objects. Pin are no longer made square but thin and oriented in the connecting direction. Use the new fused net for unnamed components. * New: In CRL::GdsParser, implementation of SREF parsing, i.e. instances. Due to the unordered nature of the GDS stream, instances creation are delayed until the whole stream has been parsed and only then are they created. For the sake of reading back Alliance s2r GDS, we assume that any TEXT following a boundary is the Net name the boundary (component) belongs to. Create abutment box for Cells, computed from the bounding box, so the Hurricane QuadTree could work properly. Make use of the fused net for unnamed components. * New: In Cumulus/plugins/chip, complete rewrite of the I/O pad management. Now we can mix real (foundry) pads and a symbolic core. To cleanly support the de-coupling between the real part and the symbolic one we introduce a new intermediary hierarchical level, the corona. We have now: Chip --> Pads + Corona --> Core. At chip level (and if we are using real pads) the layout is fully real (excepting the corona). The Corona contains everything that is symbolic. It has symbolic wires extending outward the abutment box to make contact with the real wires coming from the pads. In the pad ring we can use corners instances (or not), pad spacers or directly draw wires between connectors ring pads. Provide two flavors: placement only or full place & route. WARNING: If routing in a second step, *do not route* the *Chip* but the *Corona*. * Change: In Cumulus/plugins/clocktree, give the modified Cell an additional extension of "_cts" (Clock Tree Synthesis) instead of "_clocked", to follow the common convention. * New: In cumulus/plugins/S2R.py, encapsulate call to Alliance S2R and reload the translated Cell in the editor. * New: In cumulus/plugins/core2chip, provide an utility to automatically create a chip from a core. To work this plugins must have a basic understanding of the pad functionalities which may differs from foundry to foundry. So a base class CoreToChip is created, then for each supported pad foundry a derived class is added. Currently we support AMS c35b4 and Alliance symbolic cmos. * Bug: In Anabatic::Configuration, read the right configuration parameter "anabatic.topRoutinglayer" (Katana), and not the one for Katabatic... * Change: In Unicorn/cgt.py, process the plugins in alphabetical order to ensure a reproductible ordering of the menus...

Added support for 2-Metal block routing in Anabatic & Katana. * New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary workaround for a Hurricane problems.

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.

In Anabatic/Katana, add support for VH gauges (real technos). * Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(), when the anchor is a RoutingPad (which must be always the case), perform the true computation of it's position based on the segment occurrence. It is a important change, previously the area was in fact the "center line" of the connector while now it is really an area (mandatory for "half-offgrid" terminals of real technologies). The change is not complete yet, the area should be shrinked by the half size of a VIA, because the area applies to the center coordinate of the VIA (to be done quickly). * Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg is created (restore connexity after a layer change) the layer of the VIA, based on the segments it connects to must be re-computed *after* the dogleg has been made. * Change: In all files of Anabatic, when comparing two layers, no longer use the Layer pointer itself, but the layer mask. This allow a transparent management of both real and symbolic layers (which do share the same mask). Real metal layers (not VIAs) will be BasicLayer and symbolic metal layers will be RegularLayer. * New: Anabatic::Configuration::selectRpComponent(), select the best RoutingPad component for metal1 terminals. Look for the metal1 component with the biggest accessibility on-grid. RoutingPad using other metals are left untoucheds. * New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the neighbor Vertex through an Edge*. This method allows to write clearer code as we no longer need to access the neighbor through the underlying GCell. Also add proxies for GCell methods in Vertex. * Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when a component with multiples vertexes is reached *and* two of it's vertexes are reached *at the same time* (one from which we backtrack and one still in the queue) extraneous edges may be created by _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1". To solve this, Dijkstra::_toSource() is modificated, the "from" edges of the newly reacheds vertexes are reset to NULL, *except* for the one we will be backtracking from. That is, the one given in the source argument. * Change: In Anabatic::NetBuilder class, put the various Hooks and RoutingPad sorting functions as class ones. * Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag. This unset flag was causing AutoContactTurn::updateTopology() to not work as expected and making gaps, this was the cause of the last remaining warnings about layer connexity.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

Configuration::Configuration ( const Configuration& other )
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!

Second version of the antenna effect protection. * Change: In EtesianEngine::globalPlace(), disable the call to antennaProtect(). First reason is that, after all, Coloquinte do not handle so well the resizing of the cells "on the fly", it overspill the boundaries sometimes. Second reason is that as we cannot know the routing tree at this stage, we will not be able to choose the correct points for diode insertions. We only have a Steiner tree wich may not be the same as a density driven Dijkstra. * Change: In Etesian::Area, the Occurrence to the Instances where not stored in a uniform way. Some where starting from the placed sub-block, some where starting from the top level (corona), making their processing (and remembering it) tricky. Now, they are all expressed from the top cell (corona). The coordinate system is now systematically the one of the top block (*not* the block). Create various overloaded functions EtesianEngine::toCell() and EtesianEngine::toBlock() to ease Occurrence & coordinate translations. * New: In Etesian::Slice::createDiodeUnder(), add a X position hint. Search is done by going through the whole slice range and minimizing the distance to the hint. If it starts to be too slow, we may optimize. * Bug: In EtesianEngine::toColoquinte(), the placement of the top level external pins was not taken into account (this at last explain their weird positioning). * New: AnabaticEngine::antennaProtect(), new algorithm to avoid antenna effect. This step must be done *after* global routing and *before* detailed routing. This way we have access to the real routing and can mend it (along with the netlist) to insert diodes at the rigth points. From the global routing we build clusters (DiodeCluster) of RoutingPads connected through a set of wire whose total length is below the antenna effect threshold. Long wires connecting the clusters are also tagged because we need to put a diode between them and the first RoutingPad of the cluster. This is to avoid a long METAL2 wire connecting to the RoutingPad before the diode is connected through METAL3 (in case of misalignment). This protection is not even enough. For *very long* wires, we needs to put *more* than one diode (this is to be implemented).

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 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type...

2016-05-23 09:15:25 -05:00
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!
2018-04-16 05:10:48 -05:00
Complete the modularization of the detail routing converter. * New: In Anabatic::NetBuilder, set all the attributes as private and create accessors and mutators. Finish virtualising all GCell build methods and transfer them into the NetBuilderHV class. Build methods now return a boolean to tell if the GCell was processed or not, to allow cascading in the "big switch". Reorganise the "big switch" in separate sections only partially cascading. Truly fuse the *big switch* for channel routing and over-the-cells. Create a new method "_do_globalSegment()" to delagate the drawing of global segments between two GCell to the derived classes.

{ return _gmetalh; }
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 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic.

Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

DRC correct on Arlet6505 / TSMC C180. Integrate new features and bug fixes so the Arlet 6502 benchs successfully passes real DRC with reference industrial tools. Short summary: * Manage minimum area for VIAs in Katana::Tracks. * Allow different wire width for wires perpandicular to the prefered routing direction. * StackedVIAs used in the clock tree no longer assume an uniform routing grid (same offset & pitch all the way up). * Some hard-coded patches in PowerRails for FlexLib. * New: In CRL/symbolic/cmos/kite.py & cmos45/kite.py, update the RoutingLayerGauges by adding the new PWireWidth parameter. Always zero in case of symbolic layout (too fine tuning). * New: In CRL::RoutingGauge, add accessor to PWireWidth parameter. Modify the clone method. * New: In CRL::RoutingLayerGauge, add new parameter "PWireWidth" to give the width of a wire when it not drawn in the prefered routing direction. If it is set to zero, the normal width is used. * New: In CRL::PyRoutingGauge, export the updated constructor interface. It is *not* backward compatible, one must add the PWireWidth parameter in the various kite.py configuration files (in etc/). * Change: In AnabaticEngine::_gutAnabatic(), disable the minimum area detection mechanism, replaced by a more complete one in Katana::Track. Left commented out for now, but will be removed in the future. * Change: In Anabatic::AutoContact::updateLayer(), now systematically calls setLayerAndWidth() to potentially resize the VIAs. This is needed in real mode as VIAs are *not* macro-generated but have their real final size. * Change: In Anabatic::AutoContact::setLayerAndWidth(), select the width and height of the contact using the gauge wire width *and* perpandicular *wire width*. * Change: In Anabatic::AutoSegment::_initialize(), the "VIA to same cap" to PWireWidth/2, this will be the size of the VIA in the non-preferred direction at the end cap (non-square in real mode). * Change: In Anabatic::AutoSegment::getExtensionCap(), makes different cases for symbolic and real. Use raw length in real, add half the wire width in symbolic. Add a flag to get the extension cap *only*, not increased of half the minimal spacing. * Change: In Anabatic::AutoSegment::bloatStackedStrap(), enhanced, but finally unused... * New: In Anabatic::AutoSegment::create(), use the PWireWidth when the segment is not in the preferred routing direction (and of minimal width). * New: In Anabatic::Configuration, add new getPWirewidth(), DPHorizontalWidth() and DPVerticalWidth() accessors. * Change: In AnabaticEngine::setupPreRouteds(), skip components in in "cut" material. We are only interested in objects containing some metal (happens in real mode when VIAs cuts are really there). * New: In Katana::PowerRailsPlanes::Rail::doLayout(), add an hard-coded patch that artificially enlarge the *wide wire* so the spacing for wide wire is enforced. For now, two pitches on each side for "FlexLib" gauge. * New: In Katana::Track, add support to find and correct small wire chunks so they respect the minimum area rules. Two helper functions: * ::hasSameLayerTurn(), to find if a a TrackElement as non-zero length perpandicular is same layer connected to it. * ::toFoundryGrid(), to ensure that all coordinates will be on the foundry grid (may move in a more shared location). * ::expandToMinArea(), try to expand, *in the routing direction* the too small wire so it respect the minimal area. Check for the free space in the track. Track::minExpandArea() go through all the TrackElements in the track to look for too small ones and correct them. * Change: In Katana::RoutingPlane, add an accessor to get the tracks. * New: In KatanaEngine::finalizeLayout(), add a post-treatment to find for minimal area violations. * Change: In cumulus/plugins.block.configuration.GaugeConf, add a routingBb attribute that will serve as a common reference to all the functions calculation track positions. We must not have two different reference for the core and the corona. The reference is always the corona when we working on a complete chip. * New: In cumulus/plugins.block.configuration.GaugeConf.getTrack(), Simplified and more reliable way of getting tracks positions. Use the routingBb. * New: In cumulus/plugins.block.configuration.GaugeConf.rpAccess(), Make use of getTrack() to get every metal strap on the right X/Y position. * New: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(), As those wires are left alone by the router, it is our responsability to abide by the minimal area rule here. Hence the code duplication from the router (bad). Mainly wires made for the clock tree, I mean. * Bug: In cumulus/plugins.chip.configuration.ChipConf.setupICore(), the core instance must be placed on the GCell grid, defined by the slice height (X *and* Y). * Bug: In cumulus/plugins.chip.corona.Builder(), forgot to use bigvia for the corners of the inner ring. * Bug: In cumulus/plugins.chip.pads.corona._createCoreWire(), hard-coded patch for LibreSOCIO, the power/ground connectors toward the core are too wide and can create DRC errors when put side by side. Shrink them by the minimal distance.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

{ return _rg->getLayerWireWidth(depth); }
DRC correct on Arlet6505 / TSMC C180. Integrate new features and bug fixes so the Arlet 6502 benchs successfully passes real DRC with reference industrial tools. Short summary: * Manage minimum area for VIAs in Katana::Tracks. * Allow different wire width for wires perpandicular to the prefered routing direction. * StackedVIAs used in the clock tree no longer assume an uniform routing grid (same offset & pitch all the way up). * Some hard-coded patches in PowerRails for FlexLib. * New: In CRL/symbolic/cmos/kite.py & cmos45/kite.py, update the RoutingLayerGauges by adding the new PWireWidth parameter. Always zero in case of symbolic layout (too fine tuning). * New: In CRL::RoutingGauge, add accessor to PWireWidth parameter. Modify the clone method. * New: In CRL::RoutingLayerGauge, add new parameter "PWireWidth" to give the width of a wire when it not drawn in the prefered routing direction. If it is set to zero, the normal width is used. * New: In CRL::PyRoutingGauge, export the updated constructor interface. It is *not* backward compatible, one must add the PWireWidth parameter in the various kite.py configuration files (in etc/). * Change: In AnabaticEngine::_gutAnabatic(), disable the minimum area detection mechanism, replaced by a more complete one in Katana::Track. Left commented out for now, but will be removed in the future. * Change: In Anabatic::AutoContact::updateLayer(), now systematically calls setLayerAndWidth() to potentially resize the VIAs. This is needed in real mode as VIAs are *not* macro-generated but have their real final size. * Change: In Anabatic::AutoContact::setLayerAndWidth(), select the width and height of the contact using the gauge wire width *and* perpandicular *wire width*. * Change: In Anabatic::AutoSegment::_initialize(), the "VIA to same cap" to PWireWidth/2, this will be the size of the VIA in the non-preferred direction at the end cap (non-square in real mode). * Change: In Anabatic::AutoSegment::getExtensionCap(), makes different cases for symbolic and real. Use raw length in real, add half the wire width in symbolic. Add a flag to get the extension cap *only*, not increased of half the minimal spacing. * Change: In Anabatic::AutoSegment::bloatStackedStrap(), enhanced, but finally unused... * New: In Anabatic::AutoSegment::create(), use the PWireWidth when the segment is not in the preferred routing direction (and of minimal width). * New: In Anabatic::Configuration, add new getPWirewidth(), DPHorizontalWidth() and DPVerticalWidth() accessors. * Change: In AnabaticEngine::setupPreRouteds(), skip components in in "cut" material. We are only interested in objects containing some metal (happens in real mode when VIAs cuts are really there). * New: In Katana::PowerRailsPlanes::Rail::doLayout(), add an hard-coded patch that artificially enlarge the *wide wire* so the spacing for wide wire is enforced. For now, two pitches on each side for "FlexLib" gauge. * New: In Katana::Track, add support to find and correct small wire chunks so they respect the minimum area rules. Two helper functions: * ::hasSameLayerTurn(), to find if a a TrackElement as non-zero length perpandicular is same layer connected to it. * ::toFoundryGrid(), to ensure that all coordinates will be on the foundry grid (may move in a more shared location). * ::expandToMinArea(), try to expand, *in the routing direction* the too small wire so it respect the minimal area. Check for the free space in the track. Track::minExpandArea() go through all the TrackElements in the track to look for too small ones and correct them. * Change: In Katana::RoutingPlane, add an accessor to get the tracks. * New: In KatanaEngine::finalizeLayout(), add a post-treatment to find for minimal area violations. * Change: In cumulus/plugins.block.configuration.GaugeConf, add a routingBb attribute that will serve as a common reference to all the functions calculation track positions. We must not have two different reference for the core and the corona. The reference is always the corona when we working on a complete chip. * New: In cumulus/plugins.block.configuration.GaugeConf.getTrack(), Simplified and more reliable way of getting tracks positions. Use the routingBb. * New: In cumulus/plugins.block.configuration.GaugeConf.rpAccess(), Make use of getTrack() to get every metal strap on the right X/Y position. * New: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(), As those wires are left alone by the router, it is our responsability to abide by the minimal area rule here. Hence the code duplication from the router (bad). Mainly wires made for the clock tree, I mean. * Bug: In cumulus/plugins.chip.configuration.ChipConf.setupICore(), the core instance must be placed on the GCell grid, defined by the slice height (X *and* Y). * Bug: In cumulus/plugins.chip.corona.Builder(), forgot to use bigvia for the corners of the inner ring. * Bug: In cumulus/plugins.chip.pads.corona._createCoreWire(), hard-coded patch for LibreSOCIO, the power/ground connectors toward the core are too wide and can create DRC errors when put side by side. Shrink them by the minimal distance.

New method ::_resizeMatrix() to be called when the associated Cell is resized. * Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(), the *target* constraints where never merged. * Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(), now return a boolean to tell if it was ok (must not encounter a NULL GCell while progessing from source to target). * New: In Anabatic::Configuration and Anabatic:Session, create new methods: - getDHorizontalLayer() - getDhorizontalDepth() - getDHorizontalWidth() - getDHorizontalPitch() And so on for Vertical and Contact. They supply depth-independant informations about the H/V layers to build the initial detailed routing. The AutoSegment::create() methods have been modificated accordingly. * New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow" for implementing 2-Metal blocks. Rename the GCell::setXY() method in GCell::setSouthWestCorner(), move the contents of GCell::updateContactsPosition() into it and suppress it. WARNING: In case of a GCell shrink this may cause problems. But for now we only expand... New method GCell::getNetCount() to count the number of Net going though the GCell. * Change: In Anabatic::Edge, add specific support for capacity of 2-Metal routing channels. * Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()" calls by "not gcell->isAnalog()". Add more check so that the methods pertaining to the analog routing (GRData) are not called in digital mode. * New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific cases. That is, always break in case of vertical pass-through or U-turn. The global routing must always be broken in H-Channel. * New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism to ensure the revalidation. The "::revalidate()" method is then moved as "::materialize()" (overload of Go) and "::_invalidate()" becomes "::invalidate()" * Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX. * New: In GCellTopology, added support for building 2-Metal topologies. * ForkStack is now an object attribute as many methods do need it. * To push segments/hook on the stack, a new method "push()" is available. Perform NULL and fromHook checking. Can also setup _southWestContact or _northEastContact if it is the "from" edge. * N/S/E/W edges are now vector as in digital channel mode there can be more than one. * Added build topological build methods: - doRp_2m_Access() RoutingPad stem access. - _do_2m_1G_1M1() North or south access. - _do_2m_2G_1M1() North AND south access. - _do_2m_xG() H-Channel routing. * New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds. * New: In Anabatic::Vertex, new static method ::getValueString() for a friendly text rendering. * New: In Katana::DigitalDistance, support for channel routing. * Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(), for channel routing, calls to setupPowerRails() and protectRoutingPads() must be called after the core block has been fully dimensionned. ::runGlobalrouter() contains the code tasked with the grid creation and channel sizing. * New: In KatanaEngine: Added support for core block, for 2-Metal routing. May be expanded for over-the-cell routing in the future. Added methods : - isDigitalMode() - isAnalogMode() - isMixedMode() - isChannelMode() - getBlock() / addBlock() - setupChannelMode() - createChannel() * New: In Katana, new class Block to manage core blocks and perform channel routing. * New: In Katana::Session, new convenience method "isOpen()".

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

{ return _edgeHInc; }
Anabatic transient commit 2. * Change: In Hurricane, in CellWidget, enable the drawing of ExtensionGos according to the the threshold paramaters (as layers do). * Change: In CRL Core, provide DrawingStyle for Anabatic::GCell & Anabatic::Edge. Use the exact name of the ExtensionGo. In kite.conf, add settings for the size of an edge as the optimal size may change between analog & digital designs. * New: In Anabatic: - Support for fast position query using a matrix. - Computation of the Edge capacity, based on the routing gauge parameters. - Graphic display of the edges capacity. Added configuration parameters to size the bounding box of an Edge. * Bug: In Anabatic: - GCell::_moveEdges was both too complex (some cases never arise the way we divide GCells) and bugged.

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.

Basic support for FreePDK 45 completed. * New: In Commons, inspector support for std::pair<T,U>. * New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non square VIAs. The hole (cut) remains square, but the various metal extensions can now be different in X and Y. The ::getEnclosure() method now takes a flag EnclosureH / EnclosureV. * New: In Hurricane::DbU, inspector support for: std::pair<DbU::Unit,DbU::Unit> std::array<DbU::Unit,3> Must be defined here as DbU do not exists yet in Commons.h * Bug: In Hurricane::Interval::getSize(), when the interval is "full span", do not return the difference between min and max, but directly DbU::Max. (the previous result was -1 !) * New: In CRL Core Python/Technology.py, support for non square VIAs in the configuration files. Applied to FreePDK 45. * New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge is for symbolic layout or not. Exported to Python. * New: In Anabatic::AutoHorizontal::updatePosition(), differentiated computation for soure or target taking account of the VIA extension in the right segment metal (due to non-square VIAs). * Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is UP for HV gauges and DOWN for VH. * New: In Anabatic::AutoSegment::_initialize(), create a cache of the various extension length for each layer (viaToTop, viaToBottom, viaToSame). New implementation of getExtensionCap() using the previous cached extension table. See updatePositions(). New static functions to access the extension cache in the header: getViaTotopCap() ... * Change: In Anabatic::AutoSegment, in various update methods, updateOrient() must always be called *before* updatePositions() as extensions are dependant on source/target. * New: In Anabatic::AutoSegment::getEndAxes() compute the position of the first source and last target position (center/axes) on an *aligned* set of segments. * New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to signal segments that can be put on only one track. Specific case to VH gauge for a M1 vertical terminal with a M2 vertical segment. The M2 is effectively bound to the M1 axis position. * Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global and only one RoutingPad the connexion to the RoutingPad was duplicated. It was valid, but totally stupid. * Bug: In Anabatic::Session::_canonize(), for an aligned segment set, intersect the user constraints from all segments instead of only considering the canonical one. Issue a warning about too tight constraints only for symbolic gauges. It may be correct for the real ones. * New: In Katata::DataNegociate::update(), more accurate computation of the perpandicular free interval. Use segment extension cap calculation. Create a special case for fixed axis segments allowing them to find alternative free interval, try under source and under target as they are likely to be draggable segments. * Change: In Katana::Manipulator::relax(), use the extension cap value to compute the axis of the perpandicular segemnts. * Change: In Katana::Manipulator::moveUp(), now move up the whole set of aligned segments instead of just the canonical one. * Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate TrackMarkers insertions for fixed terminals. * New: In Katana::RoutingEvent::Key::Compare::operator(), segments with fixed axis are processed prior to any others. * New: In Katana::RoutingEventLoop, store segment pointers instead of ids to generate more accurate error messages. * Change: In Katana::RoutingPlane::create(), perform local track assignment only for HV gauges. * Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize" step in the automaton. Mutliple states transitions can occurs in a row if an action fails. * New: In Katana::Session::_toIntervalAxis(), normalize interval bounds so they are on track positions (by shrinking the interval). * Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.

Pin management implemented for NetBuilderHV. * Bug: In Katana::Track::expandFreeInterval(), the OutsideElement case was not handled correctly, the end index must be increased in that case. As a result, this function was returning too short an interval. This was affecting the computation of perpandicular free interval in DataNegociate::update() for perpandicular fixed but not in a track. * New: In Anabatic::NetBuilder and NetBuilderVH, now manage GCells with one Pin, and up to three globals. Used to put terminals at the edge of a block. * New: In EtesianEngine, now manage placed Pins. (done through extractInstanceName()) * Change: In CRL::RoutingGauge::getHorizontalGauge() no longer skip PinOnly gauges to find the reference one (same goes for vertical).

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.

The hole (cut) remains square, but the various metal extensions can now be different in X and Y. The ::getEnclosure() method now takes a flag EnclosureH / EnclosureV. * New: In Hurricane::DbU, inspector support for: std::pair<DbU::Unit,DbU::Unit> std::array<DbU::Unit,3> Must be defined here as DbU do not exists yet in Commons.h * Bug: In Hurricane::Interval::getSize(), when the interval is "full span", do not return the difference between min and max, but directly DbU::Max. (the previous result was -1 !) * New: In CRL Core Python/Technology.py, support for non square VIAs in the configuration files. Applied to FreePDK 45. * New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge is for symbolic layout or not. Exported to Python. * New: In Anabatic::AutoHorizontal::updatePosition(), differentiated computation for soure or target taking account of the VIA extension in the right segment metal (due to non-square VIAs). * Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is UP for HV gauges and DOWN for VH. * New: In Anabatic::AutoSegment::_initialize(), create a cache of the various extension length for each layer (viaToTop, viaToBottom, viaToSame). New implementation of getExtensionCap() using the previous cached extension table. See updatePositions(). New static functions to access the extension cache in the header: getViaTotopCap() ... * Change: In Anabatic::AutoSegment, in various update methods, updateOrient() must always be called *before* updatePositions() as extensions are dependant on source/target. * New: In Anabatic::AutoSegment::getEndAxes() compute the position of the first source and last target position (center/axes) on an *aligned* set of segments. * New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to signal segments that can be put on only one track. Specific case to VH gauge for a M1 vertical terminal with a M2 vertical segment. The M2 is effectively bound to the M1 axis position. * Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global and only one RoutingPad the connexion to the RoutingPad was duplicated. It was valid, but totally stupid. * Bug: In Anabatic::Session::_canonize(), for an aligned segment set, intersect the user constraints from all segments instead of only considering the canonical one. Issue a warning about too tight constraints only for symbolic gauges. It may be correct for the real ones. * New: In Katata::DataNegociate::update(), more accurate computation of the perpandicular free interval. Use segment extension cap calculation. Create a special case for fixed axis segments allowing them to find alternative free interval, try under source and under target as they are likely to be draggable segments. * Change: In Katana::Manipulator::relax(), use the extension cap value to compute the axis of the perpandicular segemnts. * Change: In Katana::Manipulator::moveUp(), now move up the whole set of aligned segments instead of just the canonical one. * Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate TrackMarkers insertions for fixed terminals. * New: In Katana::RoutingEvent::Key::Compare::operator(), segments with fixed axis are processed prior to any others. * New: In Katana::RoutingEventLoop, store segment pointers instead of ids to generate more accurate error messages. * Change: In Katana::RoutingPlane::create(), perform local track assignment only for HV gauges. * Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize" step in the automaton. Mutliple states transitions can occurs in a row if an action fails. * New: In Katana::Session::_toIntervalAxis(), normalize interval bounds so they are on track positions (by shrinking the interval). * Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.

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

Basic support for FreePDK 45 completed. * New: In Commons, inspector support for std::pair<T,U>. * New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non square VIAs. The hole (cut) remains square, but the various metal extensions can now be different in X and Y. The ::getEnclosure() method now takes a flag EnclosureH / EnclosureV. * New: In Hurricane::DbU, inspector support for: std::pair<DbU::Unit,DbU::Unit> std::array<DbU::Unit,3> Must be defined here as DbU do not exists yet in Commons.h * Bug: In Hurricane::Interval::getSize(), when the interval is "full span", do not return the difference between min and max, but directly DbU::Max. (the previous result was -1 !) * New: In CRL Core Python/Technology.py, support for non square VIAs in the configuration files. Applied to FreePDK 45. * New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge is for symbolic layout or not. Exported to Python. * New: In Anabatic::AutoHorizontal::updatePosition(), differentiated computation for soure or target taking account of the VIA extension in the right segment metal (due to non-square VIAs). * Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is UP for HV gauges and DOWN for VH. * New: In Anabatic::AutoSegment::_initialize(), create a cache of the various extension length for each layer (viaToTop, viaToBottom, viaToSame). New implementation of getExtensionCap() using the previous cached extension table. See updatePositions(). New static functions to access the extension cache in the header: getViaTotopCap() ... * Change: In Anabatic::AutoSegment, in various update methods, updateOrient() must always be called *before* updatePositions() as extensions are dependant on source/target. * New: In Anabatic::AutoSegment::getEndAxes() compute the position of the first source and last target position (center/axes) on an *aligned* set of segments. * New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to signal segments that can be put on only one track. Specific case to VH gauge for a M1 vertical terminal with a M2 vertical segment. The M2 is effectively bound to the M1 axis position. * Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global and only one RoutingPad the connexion to the RoutingPad was duplicated. It was valid, but totally stupid. * Bug: In Anabatic::Session::_canonize(), for an aligned segment set, intersect the user constraints from all segments instead of only considering the canonical one. Issue a warning about too tight constraints only for symbolic gauges. It may be correct for the real ones. * New: In Katata::DataNegociate::update(), more accurate computation of the perpandicular free interval. Use segment extension cap calculation. Create a special case for fixed axis segments allowing them to find alternative free interval, try under source and under target as they are likely to be draggable segments. * Change: In Katana::Manipulator::relax(), use the extension cap value to compute the axis of the perpandicular segemnts. * Change: In Katana::Manipulator::moveUp(), now move up the whole set of aligned segments instead of just the canonical one. * Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate TrackMarkers insertions for fixed terminals. * New: In Katana::RoutingEvent::Key::Compare::operator(), segments with fixed axis are processed prior to any others. * New: In Katana::RoutingEventLoop, store segment pointers instead of ids to generate more accurate error messages. * Change: In Katana::RoutingPlane::create(), perform local track assignment only for HV gauges. * Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize" step in the automaton. Mutliple states transitions can occurs in a row if an action fails. * New: In Katana::Session::_toIntervalAxis(), normalize interval bounds so they are on track positions (by shrinking the interval). * Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.

cdebug_log(112,0) << "bb.getCenter(): " << DbU::getValueString(bb.getCenter().getX()) << endl;
In Anabatic/Katana, add support for VH gauges (real technos). * Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(), when the anchor is a RoutingPad (which must be always the case), perform the true computation of it's position based on the segment occurrence. It is a important change, previously the area was in fact the "center line" of the connector while now it is really an area (mandatory for "half-offgrid" terminals of real technologies). The change is not complete yet, the area should be shrinked by the half size of a VIA, because the area applies to the center coordinate of the VIA (to be done quickly). * Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg is created (restore connexity after a layer change) the layer of the VIA, based on the segments it connects to must be re-computed *after* the dogleg has been made. * Change: In all files of Anabatic, when comparing two layers, no longer use the Layer pointer itself, but the layer mask. This allow a transparent management of both real and symbolic layers (which do share the same mask). Real metal layers (not VIAs) will be BasicLayer and symbolic metal layers will be RegularLayer. * New: Anabatic::Configuration::selectRpComponent(), select the best RoutingPad component for metal1 terminals. Look for the metal1 component with the biggest accessibility on-grid. RoutingPad using other metals are left untoucheds. * New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the neighbor Vertex through an Edge*. This method allows to write clearer code as we no longer need to access the neighbor through the underlying GCell. Also add proxies for GCell methods in Vertex. * Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when a component with multiples vertexes is reached *and* two of it's vertexes are reached *at the same time* (one from which we backtrack and one still in the queue) extraneous edges may be created by _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1". To solve this, Dijkstra::_toSource() is modificated, the "from" edges of the newly reacheds vertexes are reset to NULL, *except* for the one we will be backtracking from. That is, the one given in the source argument. * Change: In Anabatic::NetBuilder class, put the various Hooks and RoutingPad sorting functions as class ones. * Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag. This unset flag was causing AutoContactTurn::updateTopology() to not work as expected and making gaps, this was the cause of the last remaining warnings about layer connexity.

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

Specific case to VH gauge for a M1 vertical terminal with a M2 vertical segment. The M2 is effectively bound to the M1 axis position. * Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global and only one RoutingPad the connexion to the RoutingPad was duplicated. It was valid, but totally stupid. * Bug: In Anabatic::Session::_canonize(), for an aligned segment set, intersect the user constraints from all segments instead of only considering the canonical one. Issue a warning about too tight constraints only for symbolic gauges.

Create a special case for fixed axis segments allowing them to find alternative free interval, try under source and under target as they are likely to be draggable segments. * Change: In Katana::Manipulator::relax(), use the extension cap value to compute the axis of the perpandicular segemnts. * Change: In Katana::Manipulator::moveUp(), now move up the whole set of aligned segments instead of just the canonical one. * Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate TrackMarkers insertions for fixed terminals. * New: In Katana::RoutingEvent::Key::Compare::operator(), segments with fixed axis are processed prior to any others. * New: In Katana::RoutingEventLoop, store segment pointers instead of ids to generate more accurate error messages. * Change: In Katana::RoutingPlane::create(), perform local track assignment only for HV gauges. * Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize" step in the automaton.

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).

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.

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().

Diplay an error instead of crashing. * Bug: In CRL::RoutingLayerGauge::getTrackIndex(), the upper bound of the track interval must be included instead of excluded. * New: In Hurricane::Cell, add a StayOnPlugs flags for flattenNets(). To keep the RoutingPad occurrences on Plug instead of selecting physical components. * New: In Isobar::PyNet, add setAutomatic() and isAutomatic() to the interface. * Bug: In Katana::protectRoutingPads(), do not create protections on PinOnly layers (mostly metal1).

First working recursive place & route (Libre-SOC ALU16 benchmark). * New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one without instances. Now it can be software defined with the "FlattenLeaf" state. If it is flagged "flatten leaf" is will be considered as a leaf by the trans-hierarchical walkthrough. This flag is also set for Cells in the Alliance CATAL. * New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a test to prune leaf cells. * Bug: In Hurricane::getComponentOccurrences(), when calling the locator constructor, the "withLeafCells" argument was forgotten and was getting the value of "doExtraction" (wich, fortunately, was the same). * Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(), prune the leaf cells instead of the terminal ones. * Change: In Hurricane::HypreNet_ComponentOccurrences::progress(), prune the leaf cells instead of the terminal ones. * New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into account or ignore the "FlattenLeaf" flag when doing trans- hierarchical walkthrough. Not sure if it shouldn't be systematic. * New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf" mode for all walkthough. So we can stop at already placed sub-blocks. * Bug: In Etesian::toColoquinte(), when placed sub-block where present, the number of instances was under estimated, so the instance array was oversized and the end went unitialized. So we were getting all kind of strange behavior from Coloquinte... Now throw an exception if the number of instances differs from the computed size. * Bug: In Etesian::toColoquinte(), as for the instance array, now correctly compute the size with the ecluded nets (supplies, clocks). * Bug: In Etesian::resetPlacement(), event if the Cell is unplaced, go through the instance list to remove the potential feed cells. The netlist is written back after placement *with* the feed cells added. So, when loading again, they where cluttering the netlist and giving feed redefintions warning. They also generated erratic behaviors. * New: In Anabatic::NetBuilderHV, added configurations for: * 1G_1M1_1PinM3 * 1G_xM1_1PinM2 * 2G_xM1_1PinM2 * doRp_AccessNorthPin * New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell. * Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South global routing configuration was forgotten (only East/West). * Bug: In Katana::TrackFixedSegment, the blockage net was a static variable initialized at the first run. So we were getting stuck with the blockage net of the first cell to be routed. Of course, it did show only when Katana was run multiple times in the same process.

In Anabatic/Katana, add support for VH gauges (real technos). * Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(), when the anchor is a RoutingPad (which must be always the case), perform the true computation of it's position based on the segment occurrence. It is a important change, previously the area was in fact the "center line" of the connector while now it is really an area (mandatory for "half-offgrid" terminals of real technologies). The change is not complete yet, the area should be shrinked by the half size of a VIA, because the area applies to the center coordinate of the VIA (to be done quickly). * Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg is created (restore connexity after a layer change) the layer of the VIA, based on the segments it connects to must be re-computed *after* the dogleg has been made. * Change: In all files of Anabatic, when comparing two layers, no longer use the Layer pointer itself, but the layer mask. This allow a transparent management of both real and symbolic layers (which do share the same mask). Real metal layers (not VIAs) will be BasicLayer and symbolic metal layers will be RegularLayer. * New: Anabatic::Configuration::selectRpComponent(), select the best RoutingPad component for metal1 terminals. Look for the metal1 component with the biggest accessibility on-grid. RoutingPad using other metals are left untoucheds. * New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the neighbor Vertex through an Edge*. This method allows to write clearer code as we no longer need to access the neighbor through the underlying GCell. Also add proxies for GCell methods in Vertex. * Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when a component with multiples vertexes is reached *and* two of it's vertexes are reached *at the same time* (one from which we backtrack and one still in the queue) extraneous edges may be created by _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1". To solve this, Dijkstra::_toSource() is modificated, the "from" edges of the newly reacheds vertexes are reset to NULL, *except* for the one we will be backtracking from. That is, the one given in the source argument. * Change: In Anabatic::NetBuilder class, put the various Hooks and RoutingPad sorting functions as class ones. * Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag. This unset flag was causing AutoContactTurn::updateTopology() to not work as expected and making gaps, this was the cause of the last remaining warnings about layer connexity.

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

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

Groudwork for routing density driven placement. Compliance with clang 5.0.1. This commit contains two set of features that should have been commited separately. 1. Compliance with clang 5.0.1, tested with the RedHat collection llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS) with Xcode & macports. The bootstrap install system has been modificated accordingly. 2. The basic support for routing density driven placement. Related features are: * Bloat property. Each Occurrence of an Instance can be individually bloated. This property not attached to any tool to allow the placer and router to share it as wanted. Nevertheless, it is defined in Etesian. * BloatProfile in Katana, add individual Bloat properties to Instances occurrences based on the East & North overflowed edges of each GCell. * Support in ToolEngine for a "pass number" of a tool. This pass number is mainly used to make "per pass" measurements. The MeasureSet system is improved accordingly to support multiple values of a same measure. * Embryo of "P&R Conductor" to perform the place & route loop until the design is successfully placed. May be the first brick of a Silicon Compiler. * Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to the python component for macport (ex: python27). * Change: In boostrap/build.conf, put etesian before anabatic for instance occurrence BloatProperty dependency. Added option support for the "llvm-toolset-7" collection to build against clang 5.0.1. * Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates for first & second arguments must be called with <const T> and <const U> as the pair itself is const (and not simply <T> & <U>). * Change: In Hurricane::getSlot() temlate, only use "string" arguments and not const string&, simpler for template argument deduction. * Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<> template has a static member "_name". Clang did show that the template for this static number has to be put inside the namespace where the template *is defined* (i.e. Hurricane) instead of the namespace where it is instanciated (i.e. Analog). * Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must be put outside the C linkage back in the Isobar C++ namespace (clang). * Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification (clang). * Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change signature so it matches the one of the base class (clang). * Bug: In Hurricane::CellPrinter, use double brackets for initializer list (clang). * Change: In Hurricane::Breakpoint, reverse the meaning of the error level. Only error level *lesser or equal* than the stop level will be enabled. * Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the current working directory in the sys.path as in certain configuration it may not be included. * Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when encountering a RoutingPad on a top-level Pin Occurrence. The segment was generated in the wrong direction, creating DRC violations on the "mips_core_flat" example. * Change: In CRL::Measures, partial re-design of the measurements management. Now, each kind of measure can accept multiple values put in a vector. The index is intented to match a tool run number. * Change: In CRL::Histogram, add support for multiple sets of datas, indexeds with tool run number. * Change: In CRL::ToolEngine, add support for multiple pass number, add addMeasure<> templates for the various data-types. * Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record name constants. * New: Etesian::BloatProperty, property to attach to Instance occurrences that contains the extra number of pitch to add to the cell width. * Bug: In AutoSegment::CompareByDepthLength, the segment length comparison was wrong, it was always returning true, which broke the "strick weak ordering" of the comparison. This was producing a core-dump in GCell::updateDensity() when sorting a vector<>. The end() iterator was being dereferenced, leading to the problem. * Bug: In Katana::DataSymmetric::checkPairing(), the test for segments whose axis is perpandicular to the symmetry axis was wrong ("!=" instead of "-"). * New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells() and selectBloatedInstances() to automatically select segments from overloaded edges, overloaded GCells and bloated cells. * Change: In KatanaEngine, return a more detailed success state, distinguish between global and detailed. Add support for multiple routing iterations. * New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing driven placement.

Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah! * Bug: In Hurricane, in StaticObservable::getObserver(), if the slot pointer is NULL, do not try to access the owner. Returns NULL, so the caller can be aware of the situation... * Change: In Hurricane, in BreakpointWidget & ExceptionWidget some cosmetic changes (fonts and window sizes). * Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account the constraints from the source AutoContact, as it holds the constraints transmitted by the RoutingPads and sets up by propageConstraintsFromRp(). It is likely to be a bug affecting the original Katabatic as well. * Change: In Anabatic, in RawGCellsUnder(), check that the segment is not completly oustside the cell abutment box and truncate the coordinates to the part that is inside. Use the "shrink" if we reach the east/north border. * Change: In Anabatic, in Configuration, no more decorator because we will use a true derived relationship. Katana *derives* from *Anabatic* and do not *decorate* it, so the Configuration can do the same. It also implies that we directly create a Katana engine, not an Anabatic one. * Change: In Anabatic, in Session, do not allow the opening of the Session in a standalone fashion (with a static method). Instead it must be opened using the relevant method of the Anabatic/Katana engine. This ensure we are opening the right Session type. * Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment is not part of the collection by default, but will be included if the Flags::WithSelf is set. * Change: In Configuration, all the flags value are now defined in two steps. Declared in the header and initialized in the module. This is to prevent the fact that on some cases, in relation with the Python "extern C" part modules, we need a true allocated variable. It was causing weird linking problems. A side effect is that they can no longer be used as entry is switches, have to replace them by if/else. * New: In Anabatic, new GCell::getNeighborAt() utility function. * Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with the grid type... Back annote all the edges capacity (north & east) with the reserved local capacity. * New: Complete portage of Kite over Anabatic. The new engine is christened "Katana" for Kite-Analogic. When it's capabilities and performances will be on a part with Kite, it is to completly replace it (and take back the "Kite" name). Preliminary tests seems to show that, contrary to intuition (because built on a more complex/slower grid), it is even slightly faster than Kite 8-).

Second version of the antenna effect protection. * Change: In EtesianEngine::globalPlace(), disable the call to antennaProtect(). First reason is that, after all, Coloquinte do not handle so well the resizing of the cells "on the fly", it overspill the boundaries sometimes. Second reason is that as we cannot know the routing tree at this stage, we will not be able to choose the correct points for diode insertions. We only have a Steiner tree wich may not be the same as a density driven Dijkstra. * Change: In Etesian::Area, the Occurrence to the Instances where not stored in a uniform way. Some where starting from the placed sub-block, some where starting from the top level (corona), making their processing (and remembering it) tricky. Now, they are all expressed from the top cell (corona). The coordinate system is now systematically the one of the top block (*not* the block). Create various overloaded functions EtesianEngine::toCell() and EtesianEngine::toBlock() to ease Occurrence & coordinate translations. * New: In Etesian::Slice::createDiodeUnder(), add a X position hint. Search is done by going through the whole slice range and minimizing the distance to the hint. If it starts to be too slow, we may optimize. * Bug: In EtesianEngine::toColoquinte(), the placement of the top level external pins was not taken into account (this at last explain their weird positioning). * New: AnabaticEngine::antennaProtect(), new algorithm to avoid antenna effect. This step must be done *after* global routing and *before* detailed routing. This way we have access to the real routing and can mend it (along with the netlist) to insert diodes at the rigth points. From the global routing we build clusters (DiodeCluster) of RoutingPads connected through a set of wire whose total length is below the antenna effect threshold. Long wires connecting the clusters are also tagged because we need to put a diode between them and the first RoutingPad of the cluster. This is to avoid a long METAL2 wire connecting to the RoutingPad before the diode is connected through METAL3 (in case of misalignment). This protection is not even enough. For *very long* wires, we needs to put *more* than one diode (this is to be implemented).
