Netlist compare: Ambiguity resolution through name matching now default (can be turned off) (#594) 
* WIP: some refactoring

* WIP: some refactoring

* Netlist compare: introducing ambiguity resolution by net names

By default now net names are used for resolving ambiguities.
If net names match, they will be used to associate nets if the
choice is ambiguous. This is usually much faster and more reliable
than trying to resolve ambiguities through topology analysis.

This feature can be disabled using "consider_net_names(false)" in
the LVS script.

* Some refactoring, Jenkinsfile modified for better test coverage

Matthias Koefferlein b91e2324d0 Netlist compare enhancement 
This enhancement targets towards a better resolution
of ambiguities. The enhancement is to utilize knowledge
about device and subcircuit equivalences to avoid stale
branches of the ambiguity resolution tree.

So far following these branches could lead to a
contradictions which render an ambiguitiy resolution
choice useless.

One effect of this change is enhanced reproducibility
of the matching log because some pointers are not
involved anymore.

Matthias Koefferlein 999c065262 Introducing iterated arrays for instances 
Iterated instances are created for OASIS files
using irregular repetitions in viewer mode.

Reason: this way, the same drawing optimization
than for iterated shape arrays can be applied.

As this is a new API feature, some adjustments
had to be made to incorporate them into the
code.

    Wildcard expansion feature on layer mapping

    Finished feature, added doc and test.

    The solution is to use placeholder indexes for the
    layer mapping which are substituted by the real
    layers when they are encountered.

Matthias Koefferlein 4acc4b96e2 First attempt to fix the issue 
Problem was caching which did not take into account the array nature
of instances.

This fix also moves the cache one level below so it is effective also
when instance tree traversal happens. This might speed up things too.

Needs testing.

Matthias Koefferlein aa28aa807a Unit tests fixed and a bugfix in the netlist compare 
One unit test was failing because the netlist compare did not
properly consider dropped pins:
* A severe bug ("g1" should be "g2")
* Incomplete detection of dropped pins upwards in the hierarchy

The general pin and net mapping scheme has been enhanced so that
net mapping to "0" is valid (this will happen in case of dropped
pins) and this condition is used to detect pins without match
requirement.

"Expressions" framework.

* $(tech_dir) -> substituted by the directory the technology file is stored in
* $(tech_file) -> substituted by the absolute path to the tech file
* $(appdata_path) -> substituted by KLayout's home directory (e.g. ~/.klayout)

Matthias Koefferlein 6648b53822 Fixed issue #419 (multiple top circuits after flatten of netlist) 
The problem is solved by always producing subcircuits for cell
instances, even if there are no connections.

The netlist comparer had to be adjusted too because subcircuits
without pins were used for representing "unknown" subcircuit pairing.

In addition, this patch should lead to a better matching of
parallel subcircuit configurations where two different subcircuits
are entirely parallel.

Matthias Koefferlein bdf5e3c124 WIP: fake pin debug issue with LVS 
Fake pins: pins that happen because something connects to a cell at an
unexpected position. Such a pin is difficult to find. The solution is
to keep those nets and nur purge them so these nets can be identified
in the layout.

Here: is_floating? will be true only if there are no pins. Hence
nets with pins are not removed. is_passive is introduced for nets -
passive nets are such that don't have elements, but a pin.
Circuits are purged if they only have passive nets.

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 cef96902ad Boundary for circuits, reverted automatic generation of global pins 
- global pins have been generated for device cells too and lead

  solved differently.

  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

Issue solved: some circuit pins may not have a net - these

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 e424a88c90 WIP: netlist compare algo 
1.) Can identify transistor netlists without subcircuits
2.) Ambiguities stay unresolved

Next steps: assign ambiguous nets one by one and continue
in case of ambiguitites.

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.
