Basic goal is to align ngspice and KLayout Spice
format comprehension. ".options scale" was implemented
together with a number of other patches.
Consistency has been confirmed with respect to these
features and formula evaluation.
Fixed polygon rasterizer.
Reason was the clip edge function that delivered
vertical edges from skew ones due to rounding.
These must not be skipped when exactly on a pixel
boundary as true vertical edges are.
Bug fix: re-enabling of trace all nets tests, establishing dummy
names for layers in all cases - otherwise layers do not have a
reference for LayoutToNetlist persistence.
* Fixed issue-1135 (LVS mismatch on parallel devices)
The fix consists of a more elaborate device identity analysis
following the topological matching. In this step, the devices
are identified according to their connections and parameters.
It is important to properly identify devices taking their
parameters into account as well as their connections.
* Second part of issue fixed (inverter chain ambiguity)
* Added test
* Updated tests
* Updated golden test results
* Updated golden test data for Windows

* First attempt to fix. Rather experimental.
* Debugging and bug fixing
The basic issue was a missing break
However, correct computation of cache results for instance-to-instance cluster
interaction is implemented
Plus: identical and overlapping instances are no longer ignored except in the
case of exact duplicates. Otherwise these instance generate dead nets which
are not connected elsewhere.
* Added tests, fixed duplicate cells test, added missing files.
* Code simplification (removed invariant from transformation in cluster-to-cluster interaction cache)
* Skipping cell instance duplicates as some real-world testcases mandate so
* Updated test data
The bug was that while iterating a Region during the gate traversal,
the "select_interacting" was triggering a sort() which changed the
order.
Solution is to pre-sort when iterators are issued also when the
iterator is non-region selecting. This way, plain and region query
iterators can be used together. In addition, the dirty flag scheme
of Cell+Shapes was cleaned up a little for bboxes.
