* Bug: In CRL/etc/symbolic/cmos/plugins.conf, rails dimensions are no
longer expressed directly in lambda. Must be created using helper.l().
* Change: In CRL::ApParser, slightly more smart management of Pin width.
Must normalize Pin behavior between Alliance & Hurricane as in
Alliance they have only one dimension.
* Change: In CRL::LefImport, if a net name end with "!", assume it's a
global one. Have to check this naming convention.
* Change: In Anabatic::NetBuilderHV::_do_1G_1PinM3() & _do_1G_1PinM2()
now implemented. Needed for the corona routing support.
* Change: In AnabaticEngine::setupPreRouted(), exclude segments outside
the abutment box.
* Change: In KatanaEngine::PowerRails, remove the I/O pad support as now
we route only inside the Corona. So only one vdd/vss/ck are supported.
* New: In cumulus/plugins/ChipPlugin.py, complete rewrite of the chip
support:
* Uncouple pad I/O ring whith real cells (foundry) from a symbolic
core. A new intermediate level "corona" is introduced to handle
the real/symbolic transition.
* Ability to explicitly setup position of the pads on the chip side
in case of uneven distribution.
* Enable clock tree to be build with 3 metal only (M2 to M4) instead
of (M2 to M5).
