Matthias Koefferlein 2b447854f9 Enhanced matching of blackbox/pin ambiguities
Previously: matching of blackbox pins was enforced
by using pin names for passive nets in the compare.
Problem: no match was achieved when pins are not
named or not named consistently.

In this case, it's desirable to treat them as
ambiguous.

The new solution is to let the ambiguity resolver handle
that using an extended definition of the net names:
it will take the pin name into account if an unnamed net
is attached to a pin.

In addition, net ambiguities are projected to pin
equivalence now. This also will propagate symmetry
through nested blocks (dbNetlistCompareTests:20_BusLikeConnections).

Matthias Koefferlein c24c0933bf Bugfix: blackbox mode/abstract pins
Abstract pins are created when pins are not attached to any or only to passive nets
(passive nets are those without device terminals or subcircuit pins).

1. Such pins were treated swappable. Now named pins will not be treated
   swappable but are mapped by name. This enables blackbox models where
   the pins are labelled and must correspond to schematic pins.
2. A bug was present which lead to incorrect handling of abstract
   nets in net compare.

Reduce risk of DRC polygon split artefacts in deep mode (#722)
* Fixed a segfault with simple 'klayout -v'

* is_halfmanhattan polygon predicate, confine polygon splitting to halfmanhattan

Splitting any-angle polygons for area reduction in the
deep processor creates a risk of introducing grid-snap
artefacts. Hence we avoid this.

Matthias Koefferlein 9cf0a9e659 Major enhancements for DRC feature (universal DRC)
Main issue: universal DRC scheme and rectangle filtering/opposite filtering/shielding.

The space function required some enhancements to accomodate symmetric interactions.
Now there are symmetric edge pairs. Space initially runs twofold (primary to foreign)
but produces symmetric edge pairs. These are filtered later unless converted before.

2019-03-10 19:35:13 +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:

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 02819c5f1e Hash functions and fuzzy compare for RBA
RBA now provides a hash method for Box, Edge, EdgePair, Trans,
Polygon, SimplePolygon, CellInstArray, LayerInfo, Path, Text,
Point and Vector.

eql? is mapped to ==.

==, != and < act "fuzzy" for the double-typed variants.

Hence, these objects can be used as hash keys now.
