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

Anabatic transient commit 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.

Transparently manage the overflowed edges. - In GCell_Edges, correct a filtering bug when not all sides are selecteds. - New GCell::getEdgeTo() to find the edge between two adjacent GCells. - New GCell::unrefContact() to automatically removes global contacts no longer used by any global segments (used during the ripup step). - In Dijkstra::load(), now able to "reload" and already partially or completly routed net (look for Contact of "gcontact" layer and their attached segments). - In Dijkstra, keep the last net loaded until the next one is.

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

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

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

Transparently manage the overflowed edges. - In GCell_Edges, correct a filtering bug when not all sides are selecteds. - New GCell::getEdgeTo() to find the edge between two adjacent GCells. - New GCell::unrefContact() to automatically removes global contacts no longer used by any global segments (used during the ripup step). - In Dijkstra::load(), now able to "reload" and already partially or completly routed net (look for Contact of "gcontact" layer and their attached segments). - In Dijkstra, keep the last net loaded until the next one is. Put the cleanup operations in an isolated function "_cleanup()". - In Dijkstra::_selectFirstsource() and run(), load first source component made of multiple vertexes. - In Dijkstra::_trackback(), link the Net segments to the Edges. - New Dijkstra::ripup(), Dijkstra::_propagateRipup() to perform the ripup of one edge of a Net (must be loaded in Dijkstra first). Dijkstra::_tagConnecteds() setup the connexId of a set of Vertexes - that are connecteds through edges *with* segments. - In GraphicAnabaticengine & GlobalRoute.cpp, embryo of a global routing tool with ripup & reroute.
