Matthias Koefferlein 550e2622bf Put more amphasis on net names to resolve ambiguities 
The problem was that with the floating test case, the
ambiguity resolution sometimes assigned the wrong pins
and floating pins/connected pins were swapped.

One option is to make the ambiguity resolver consider
the pin connection state when tenatively evaluating
nodes.

Another option is to put more emphasis on net names
and use them for ambiguity resolution. This has helped
here.

Matthias Koefferlein 60ed0cdc89 Updated test golden data (mainly: nets are not purged when there is a subcircuit pin on it) 2019-08-29 23:26:03 +02:00
Matthias Koefferlein b1acfe9587 Tried a better deal with floating pins 
1.) is_floating is now only true if there is no device
    and no subcircuit on a net. This means we only purge
    nets if they are really floating. So far we purged
    nets without pins which lead to the mismatch:

    Before purge:
      Layout:            (net) <--> DEVICE.TERMINAL
      Schematic:           PIN <--> DEVICE.TERMINAL

    After purge:
      Layout:           (null) <--> DEVICE.TERMINAL
      Schematic:           PIN <--> DEVICE.TERMINAL

    (null does not match any net)

2.) circuit pin matching was a bit picky. Only when
    one circuit did not have pins, matching was sloppy.

    In real cases however, circuits may have unconnected
    pins:
    - top level pins without a counterpart (no label)
    - subcircuits pins which are not used

    We catch both cases by refining the match: if a pin
    is not used, it does not need to match against
    any other pin. It's reported as "matching against null"
    though.

Matthias Koefferlein 444e10d32f WIP: rerun LVS, partial LVS 
Rerun LVS: a button is provided which allows re-running
the LVS or netlist extraction from the netlist browser.
TODO: a generic concept for triggering the generators

"Partial LVS" is a feature where it's possible to
select a layout subcell - running LVS then will only
compare against the corresponding schematic subcell, not
the whole tree. The magic is done by "align" which will
remove the upper hierarchy part.

Matthias Koefferlein 1bc03c3b79 Implement "M" parameter for Spice 
This implementation is pretty simplistic and
applies "M" the following way:
* R: R(final) = R/M
* L: L(final) = L/M
* C: C(final) = C*M
* M: W(final) = W*M
* D: A(final) = A*M
* Q: AE(final) = AE*M

The other parameters (specifically the other
geometry parameters) are not scaled yet.

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

otherwise the model can't be built consistently.

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.
