* Change: RoutingGauge in KatanaEngine::annotateGlobalGraph(), when
accounting for obstacles, skip new types of RoutingGauges that
are not accounted either when computing initial edge capacity in
EdgeCapacity CTOR. Now only take into account the "Default" kind.
* New: In LefImport::LefParser, add support for LEF Polygons that are
translated into Hurricane Rectilinears.
* Change: In LefImport::setMergeLibrary(), the default behavior for the
LEF parser is to create a new separate library under LEF/<lib_name>
for each file. But if the various cells are put each one in it's own
cell, this is suitable. So we can now set a library beforehand into
which they will be all put.
* New: in CRL/technos.node180.gf180mcu, configuration files for the
GF180MCU open PDK.
* New: in cumulus/designflow.technos, added a setupGF180MCU_GF() to
initialize the GF PDK.
In order to accurately find the rectangles (Components) causing a short
circuit, we need to aggregate the equipotentials as soon as we starts
to merge the tiles. Because tiles being a union set, the tree compression
forbid to know which tile overlap which one afterwards. So the equipotentials
are created early on the fly. We also add an accounting of all the net's
components (Plug excluded) to know if it is fully included in the
equipotential. If not, we have an open.
This is an impacting change from the previous version in which we build
the equipotentials *after* aggregating the tiles only. The added cost
comes from the number of equipotential merging that we have to perform
when we merge tiles. Almost two times slower. May need to have a deep
look on how to optimize it later (efficient merge or keeping the order
tiles where merged).
* Change: In Occurrence::getCompactString(), when the path is void,
still display a double colon (::) instead of just one so we know
for sure that the it is void.
