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 c6b48acc76 Some small enhancements
LVS: max_branch_complexity was wrong and missing from doc.

Updated test cases so MSVC 2017 builds should pass.

Windows build.bat updated so debug builds can be made.

Matthias Koefferlein 782f6fe601 BUGFIX: the L2N and LVSDB writer was writing too much

Because of this fix, many testdata files have to be updated.

Matthias Koefferlein ca747771ac Allow preempt LVS configuration
same_nets, equivalent_pins, same_circuits and same_device_classes
can now be given at the beginning of the LVS script. This will
simplify building universal scripts with the run specific part at
the beginning (one "load" section).

The price are somewhat less specific error messages when something
fails in these methods.

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 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.
