Matthias Koefferlein 020b874083 WIP: more device classes - unit tests for classes 2019-06-14 20:41:38 +02:00
Matthias Koefferlein 0d623bc57a Avoid netlist extraction issues with duplicate instances 
So far, duplicate instances have lead to net propagation
into parent cells and floating nets. This is fixed by ignoring
duplicate instances where possible.

Matthias Koefferlein ebd00c186b Enhancements for net export feature 
- some refactoring
- better performance (was slow because layer iteration
  was done outside of loop and recursive cluster iterator)
- with selected nets, only the required hierarchy is
  produced. For this a new argument is added to
  LayoutToNetlist::create_cell_mapping (nets) which
  allows selecting the nets for which a cell mapping
  is requested

device classes are persisted.

Matthias Koefferlein 89ffd7e3da WIP: Simple SPICE reader. 2019-04-01 22:46:33 +02:00
Matthias Koefferlein 9613ad72c8 WIP: netlist compare - using it for more tests 
Issue solved: some circuit pins may not have a net - these
need to be ignored.

Requirement: all pins with a net must be mapped.

Detached pins are not present in the mapping table.
A dummy mapping table was introduced to allow dropping
of pins in the second circuit too.

Output of compare should not depend on memory location
anymore and pin mismatch reporting should include all
pins.

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.
 2019-03-31 09:53:51 +02:00
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 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.
