Show the device parameters for netlist devices (same as
for netlist browser)

Matthias Koefferlein b4fa4b1bae Flattening of layout with circuit flattening.
Technically, the layout isn't flattened, but connections are made
which allow regenerating the layout even after the circuit
has been flattened.

Matthias Koefferlein 9cad9ca024 Fixed missing initialization of device_scaling in LayoutToNetlist. 2019-07-24 20:49:56 +02:00
Matthias Koefferlein afb5cea576 Added "device_scaling" to LVS
Plus: added some missing files

Implementation details:
* scaling factor was introduced in DeviceExtractor::extract
* for easy implementation this is available in "sdbu"
* "sdbu" is made available in GSI
* to test this, the db::compare_netlist had to be enhanced to
  exactly check device parameters
* enhancement of LVS script framework and doc updates

Matthias Koefferlein cef96902ad Boundary for circuits, reverted automatic generation of global pins
- global pins have been generated for device cells too and lead
  to implicit pins which may not be desired. The original problem
  was how to make abstract circuits comparable. This has to be
  solved differently.
- Circuit boundaries are good for displaying the boxes for
  abstract circuits

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 f931b6a1c1 Bugfix: avoid an assertion in the netlist browser
Reason: when a circuit does not have pins and is top level,
but the reference has pins, the reference pins are regarded
to match against (nil). This case has to be reported properly,
otherwise the model can't be built consistently.
