Matthias Koefferlein 0c6ead6f90 WIP: introduced boundary into L2N format so we have something to display for abstracts. 2019-07-09 01:18:23 +02:00
Matthias Koefferlein 993ef78575 WIP: some cleanup/enhancement 
General topic: abstracts and swappable pins.
Issue: we work bottom up and assign pins. This is the
basis for net graph building. But swappable means those
pins can change. The compare works fine, but debugging
output is strange: as the pin assigned is fixed, the nets
found to be attached to a circuit might not fit any
proposed pin pair (which does not contain swapping).

The problem gets worse with abstracts.

The enhancements are
- Such cases generate only warnings in the browser
  and the message says swapping might be the case
- Floating nets are treated differently. This should
  lead to a better performance for abstracts/black boxes,
  but in case of disconnected pins (due to wire errors),
  floating nets happen to create mismatches in the nets above.
- Net graph building does not consider swappable nets. In
  case of two swappable pins this wouldn't be an issue, but
  for more than two this would create ambiguities and
  prevent topological matching.

Plus: Debug output option for net graph

Tests updated

Matthias Koefferlein 0e5ecdc36b Attempt to make LVS compare output a little more predictable with boundary cases 
- For unattached subcircuit pins no error should be reported
- For abstract nets, graph propagation through subcircuit pins isn't attempted.
  Abstract nets are only dummy-associated currently.

Matthias Koefferlein 624811d55e WIP: fixed a basic issue with empty layers 
Previous: empty layers occupied a special layer in the DSS
But what when empty layers are required as outputs?
ONE layer isn't good -> would overwrite the layer and it's
no longer empty for others.
So we need to keep the layers separate.

Merge pull request #280 from KLayout/issue-276 
Fixed #276 (Layer properties name cannot be updated)
 2019-06-18 18:44:55 +02:00
Matthias Koefferlein eecb62906c Fixed #271 (proposal, more choices for the cell origin on 'make cell') 2019-06-18 00:52:13 +02:00
Matthias Koefferlein 56c622053f Fixed #276 (Layer properties name cannot be updated) 
In addition, this fix includes Python-related fixes: because
of the short lifetime of Python references, the functionality
was not as expected sometimes. Keeping copies of LayerPropertiesIterators
helped. Some tweaks were required to maintain the delete() semantics.

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

Matthias Koefferlein 6f263211e2 Some more fixes for picky gcc 4.4.7 2019-05-31 00:41:11 +02:00
Matthias Koefferlein 9d01cb5282 Some updates (res/cap device ex, flatten preserved geometry) 
- Two new device extractors for resistors and caps
  (two-terminal only)
- R and C device classes have A and P parameters now
- A generic concept to supply terminal output layers
  for device extractors (tX).
- Converted offset to transformation for devices:
  this was required to make circuit flattening preserve
  the geometry (transformation of devices)
  L2N/LVSDB formats have been extended for this.
