Matthias Koefferlein b391b4510f WIP: can compare empty circuits now
Empty circuits play a role as abstracts. They
are compared by using the pin names the nets
are attached to. The implementation change is:
* nodes without device terminals or subcircuit pins
  are compared through their net properties (count
  and name of pins attached)
* some enhancements of the net string serializer
  have been made to account for pin name mismatches.

Matthias Koefferlein 2452c72d2d WIP: netlist compare deployed for netlist extractors
Some enhancements were required:
* Clusters left over from joined clusters must not be
  turned into nets: this leads to dummy nets.
* null Nets can happen as targets of edges. Don't assert
  in this case but treat null nets as identical for both
  netlists.
* Don't resolve ambiguous nets if there are options to
  do this non-ambiguously.
* logger can be null
* Added compare_netlists to dbTestSupport

Matthias Koefferlein e424a88c90 WIP: netlist compare algo
1.) Can identify transistor netlists without subcircuits
2.) Ambiguities stay unresolved

Next steps: assign ambiguous nets one by one and continue
in case of ambiguitites.

Flat extraction requires that texts of subcells are not
considered. Otherwise they pollute the net namespace of
the top cell.

Matthias Koefferlein 37cc84908e Updated test because of edge pair normlization 2019-03-09 20:25:45 +01:00
Matthias Koefferlein 6932977273 A few bug fixes and test updates
- edge pairs are normalized before turning them into polygons.
  This makes flat and deep implementation more consistent.
- deep region and flat regions were not cooperating in geo
  checks
- unnamed layers are not registered in make_layer - this
  does not make sense and will just hold a fake ref
- tests now use GDS to represent texts after transformation
  (with orientation, OASIS can't do this)
- texts are more consistently handled in the tests
- test debug output is not written in the same format
  than golden data unless special normalization is
  requested.
- a non-orientable polygon was converted to orientable in
  a text because this can be represented in GDS consistently
- DRC testsuite uses "polygons" instead of "input" to achieve
  identical behavior for deep and flat mode with respect to
  texts
- dbRegionTests are updated because texts are not allowed
  for non-original layers too

Matthias Koefferlein 745696507f Two bug fixes in DRC related to flatten:
- Merge semantics wasn't transferred to flat region
- Merge semantics wasn't set at all in deep region

Matthias Koefferlein 8b29b30ff9 WIP: more consistent text handling
Texts are not only kept inside original layers, but
also inside deep layers. This enables using texts
from DRC.

However, texts in deep layers are kept as markers.
Mostly they are converted back to texts, but the
orientation will be lost.

The change eliminates the need to using Iterators
in DRC instead of original layers and use of
label layers in deep mode.

A drawback is the presence of marker shapes in
deep mode (unless polygon layers are created).
Also, text output to RDB is not supported from
deep layers currently.

kept.
