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.

Matthias Koefferlein 510c675d21 Test cases for DRC-based net extraction and flat extraction
Flat extraction requires that texts of subcells are not

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
2019-03-09 19:40:38 +01:00
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.

Reason for the problem: the interaction test
has to keep separate "inside" records for both
below and above the scanline, not just once.
With the single record, the step in the
left polygon erased the "inside" condition.

Matthias Koefferlein 15b79c9ddb IMPORTANT BUGFIX: array repo handling
The issue: when cloning an array, the

memory leak.

Matthias Koefferlein 9c607d7663 Added a first version of the layout to netlist extraction feature
The main entry point is RBA::LayoutToNetlist which is the
GSI binding for the layout to netlist extractor. For a first
impression about the abilities of this extractor see the
Ruby tests in testdata/ruby/dbLayoutToNetlist.rb.

The framework itself consists of many classes, specifically

- RBA::Netlist for the netlist representation
- RBA::DeviceClass and superclasses (e.g. RBA::DeviceClassResistor and
  RBA::DeviceClassMOS3Transistor) for the description of devices.
- RBA::DeviceExtractor and superclasses (i.e. RBA::DeviceExtractorMOS3Transistor or
  the generic RBA::GenericDeviceExtractor) for the implementation of the
  device extraction.
- RBA::Connectivity for the description of inter- and intra-layer connections.
