Replace "unsigned int" by "Flags" in all AutoSegments collections. * Change: In Anabatic::AutoSegments collections, change the type of all the flags that where in "unsigned int" (32 bits) to Flags (uint64_t) as there is now more than 32 flags for functions. * New: In Ababatic::Constants, added new flag Flags::WithPerpands, which makes the number of flags tip over 32 bits, thus making mandatory to uses Flags and not unsigned int. * New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag Flags::WithDoglegs to allow to propagate through global segments that are connecteds via doglegs on local segments. Meaning that there is a good chance that they could be aligned. Slighly change the way we propagate on aligned segments: no longer check for VTee or HTee, but only for same direction and layer as master. * New: In Anabatic & Katana, replace all the "int", "long" and their variants by the less implementation ambiguous "int32_t", "int64_t" (and variant). This should help to better detect bit trucation in flags. Use the type to give a hint about the flags kind: - Type "Flags", for flags shared among Anabatic & Katana functions/methods (may also appear in some objects states). - Type "uint32_t" for flags belonging to an object internal state of from Hurricane functions flags (those should be grouped in a Flag subclass in a perfect world).

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.

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).

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

Katana routing algorithm adjustements for analog routing. * Bug: In Hurricane::Interval, the ::getSize() method was returning a negative length when the Interval was empty. Now return zero. This was causing slight cost functions side effect when computing the overlap of a segment with another one belonging to the same net (i.e. shareDelta) * Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal position for the axis is indeed inside the GCell interval. * Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink applied to GCells sides. Interval are of the type [min:max[ so after symmetric transformation they become ]smax:smin]. Apply a correction so that they are [smax:smin[ and could be merged with the paired interval (the one without symmetry applied). * Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive, and must be *substracted* to the "delta" (not *added*). * Bug: In Katana::_computeNetOptimals(), now skip the already processeds AutoSegments instead of re-processing them. * New: In Katana::AutoSegment::computeOptimal(), improved computation of the axis hint: - For analog net, propagate through the simple doglegs to find attractors. - Restrict the allowed interval to the union of GCell sides and segments constraints that are terminals. - Consider a local as "long" if it's length exceed 20 the P-pitch. (maybe make that a tool parameter).

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-).

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

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

Correct bug in AutoHorizontal::getGCells() line probing. * Bug: In Anabatic::AutoHorizontal::getGCells(), the y coordinate used to perform the line probing for neighboring GCells, cannot use the segment constraints because they are not correctly set this early. Instead we have to rely on the global router having put them in the correct position (i.e. at the center of the GCell side). The y position must also be epsilon-decreased if it is on the border of the nothernmost GCell. This apply to AutoVertical as well. * Change: In Anabatic::GCellTopology CTOR, when counting the RoutingPads of a GCell, compare gauge layers using their masks instead of the Layer itself. This allow for Analogic layers to be recognizeds.

Replace "unsigned int" by "Flags" in all AutoSegments collections. * Change: In Anabatic::AutoSegments collections, change the type of all the flags that where in "unsigned int" (32 bits) to Flags (uint64_t) as there is now more than 32 flags for functions. * New: In Ababatic::Constants, added new flag Flags::WithPerpands, which makes the number of flags tip over 32 bits, thus making mandatory to uses Flags and not unsigned int. * New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag Flags::WithDoglegs to allow to propagate through global segments that are connecteds via doglegs on local segments. Meaning that there is a good chance that they could be aligned. Slighly change the way we propagate on aligned segments: no longer check for VTee or HTee, but only for same direction and layer as master. * New: In Anabatic & Katana, replace all the "int", "long" and their variants by the less implementation ambiguous "int32_t", "int64_t" (and variant). This should help to better detect bit trucation in flags. Use the type to give a hint about the flags kind: - Type "Flags", for flags shared among Anabatic & Katana functions/methods (may also appear in some objects states). - Type "uint32_t" for flags belonging to an object internal state of from Hurricane functions flags (those should be grouped in a Flag subclass in a perfect world).

New refresh method "updateSize()" and flag CntInvalidatedWidth. to compute the size. In AutoContactTerminal, compute the constraint box according to the width of the segment. * New: In Anabatic::AutoSegment, flags are now implemented as "static const" attributes of the class. The flags are stored into a uint64_t as they are more than 32. Added new flag "SegWide" and associated predicates. * Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(), uses the simpler overload of AutoSegment::create() in order to detect the wire width automatically. * New: In Katana::Manipulator, split insertToTrack() and forceToTrack() into a one-track method and a segment level method that iterate over the track span of the segment. * New: In Katana::SegmentFsm, for each cost in the table, now allow access to a specific track. So the base functions have now two parameters: "icost" and "itrack" (has a cost can have multiple tracks in the case of wide segments). * Change: In Katana::TrackElement, remove the index of the element inside it's track, as for a wide segment it will not be meaningful for the non-base track. This means that we have to use the Track::find() method each time instead. Remove the wide flag, as it is a duplicate of the one in AutoSegment. Added a getTrackCount() method to tell the number of track the segment is inserted into. Needed in the Track destroy step to delete a segment only when the last track that refers it is destroyed. Added getSymmetricAxis() to correct the computation of the symmetric base track in case of wide segment as the base track is not centered but the the leftmost one. * Change: In Track::insert() insert wide segments in their whole track span. * Change: In TrackCost, create an array of costs according to the segment track span. * Change: In TrackSegment::create(), now activate the factory and create wide segments. * Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation problem (ever shifting to the right).

Replace "unsigned int" by "Flags" in all AutoSegments collections. * Change: In Anabatic::AutoSegments collections, change the type of all the flags that where in "unsigned int" (32 bits) to Flags (uint64_t) as there is now more than 32 flags for functions. * New: In Ababatic::Constants, added new flag Flags::WithPerpands, which makes the number of flags tip over 32 bits, thus making mandatory to uses Flags and not unsigned int. * New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag Flags::WithDoglegs to allow to propagate through global segments that are connecteds via doglegs on local segments. Meaning that there is a good chance that they could be aligned. Slighly change the way we propagate on aligned segments: no longer check for VTee or HTee, but only for same direction and layer as master. * New: In Anabatic & Katana, replace all the "int", "long" and their variants by the less implementation ambiguous "int32_t", "int64_t" (and variant). This should help to better detect bit trucation in flags. Use the type to give a hint about the flags kind: - Type "Flags", for flags shared among Anabatic & Katana functions/methods (may also appear in some objects states). - Type "uint32_t" for flags belonging to an object internal state of from Hurricane functions flags (those should be grouped in a Flag subclass in a perfect world).

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