Raw Normal View History

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.

Improved management of AutoContactTerminal for VH gauges (real ones). * New: In Anabatic & Katana, add the new "drag" feature. With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new routing configuration that was not efficiently handled did appear. While the preferred routing direction for metal1 is officially horizontal, due to the way the standard cell must be designed, their metal1 terminals are still verticals (or punctuals). Thus, when connecting to them, we face the case where the metal1 terminal (RoutingPad) is vertical *and* the metal2 wire is also vertical. With that setup, the position of the AutoContactTerminal via12 cannot be deduced, it may range all the way over the metal1 RoutingPad. What may define it's position is the metal3 the metal2 finally connects to. That, is, when we have one horizontal (the metal3) and one vertical (the metal1 RoutingPad). The intermediate wire of metal2 can be kept to a minimum size by "dragging" the via12 close to the via23 when the metal3 wire is moved. * New: In Anabatic & Katana, problem of closely vertically aligneds RoutingPads in metal1 is managed first in PreProcess by restricting the span of the connecteds metal3 and in _makeDogleg also by restricting the span even more tightly (to the RoutingPad itself). * New: In Anabatic::AutoContactTerminal, add the "drag" support. Automatically check if the connecting segment is in the same direction as the RoutingPad, if so, sets the "SegDrag" flag. The dragging state can be known with the "::canDrag()" predicate. * New: In Anabatic::AutoHorizontal, add the "drag" support. The drag state can be known with the "::isDrag()" predicate. In "::_makeDogleg()", when making a dogleg on a dragable segment pass the drag state correctly and restrict the perpandicular span of the perpandicular to the RoutingPad (though segment user constraints). If we make a dogleg on the metal2 is it likely than we cannot go straigth out vertically from the RoutingPad, so the new perpandicular *is* restricted to the RoutingPad span. Idem for AutoVertical. * New: In Katana::Manipulator, add method "::dragMinimize()" which find a hole where to minimize a draggable segment. We finally did not use it, but keep it for potential further use. * New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local function to check for vertically aligned metal1 RoutingPads, in that case setup user constraints on the metal3 segments so they cannot completly cover the other RoutingPad with metal2. We also keep a "metal2protect()" function that create a fixed segment to lock/protect a RoutingPad. Not used for now. * New: In Katana::Session, add a RoutingPad locking event mechanism. This allows us to request the creation of a locking (fixed segment) over a draggable segment. Not used for now. Lock events are processeds before all others as they create new TrackElements. * New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()" method to find the nearest free interval in a Track after/before a position. * Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user constraints *only* if it's not an empty interval (as we use min/max functions). Idem for AutoVertical. * Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test must be inverted. Seems it never worked, but we never used it until now...

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.

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

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