Matthias Koefferlein e4078ca750 String serialization for netlists. 2019-03-18 02:00:33 +01:00
Matthias Koefferlein 510c675d21 Test cases for DRC-based net extraction and flat extraction 
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 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.

Matthias Koefferlein 9b31bd3214 Fixed crash by introducing a new scheme for storing cluster refs 
The previous implementation was based on the Instance
pointers, but these got invalidated during device cell
construction. Now an explicit copy of the instance is
kept.

Matthias Koefferlein 1f3af7bbfe Hierarchical area and perimeter and sizing 
Area and perimeter computation happens hierarchically
now. Magnified instances are supported.

Sizing is implemented hierarchically.

For anisotropic sizing, orientation variants may be
generated. For both isotropic and anisotropic
magnification variants will be created.
