Fixed issue-1111 (#1112) 2022-07-03 09:35:40 +02:00

Matthias Koefferlein 5b9f194ecc Forget last commit - problem was that golden netlists should not be compared with net names as those are node numbers and they might change with C++ STL implementation 2022-03-18 00:10:00 +01:00

Issue 1021 (#1026) - LVS match issue on SRAM sample 
* First step for solution:

Problem was: the ambiguity resolver was making decisions which later resulted in
a name conflict. Later on, another branch of the backtracking algorithm came
across the same situation but decided based on names, creating an conflict.

First part of the solution is to establish the backtracking information
during ambiguity resolution and using that rather than an alternative branch
later on. This avoids this conflict, but does not favor names as mandated
by the "use_names" flag. This will be the second step of the solution.

* Bugfixed solution (partially)

* Introducing third pass in netlist compare

The second pass is "ambiguity resolution by name" and
is skipped if "consider_net_names" is false. The third
pass then is ignoring the names.

* Bugfix

* Comment fixed, test updates

* Added tests

* Added test data variant for CentOS 8

Issue 1011 (#1027) - DRC violation on texts in deep mode 
* Fixed issue-1011 by using single-point polygons for texts in deep mode. Tests need fixing.

* Updated tests (text become a single point)

* Added test for issue-1011

Matthias Koefferlein c24c0933bf Bugfix: blackbox mode/abstract pins 
Abstract pins are created when pins are not attached to any or only to passive nets
(passive nets are those without device terminals or subcircuit pins).

1. Such pins were treated swappable. Now named pins will not be treated
   swappable but are mapped by name. This enables blackbox models where
   the pins are labelled and must correspond to schematic pins.
2. A bug was present which lead to incorrect handling of abstract
   nets in net compare.

Matthias Koefferlein fcb966393a Fixed #806: first, the internal error gone. Second, the implementation of custom comparers is simplified as the 'equals' method does not need to be implemented. 2021-05-26 22:39:28 +02:00

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.
