Matthias Koefferlein 5962d66940 WIP: major enhancements with respect to device handling
The device handling in the netlist extractor was now
entirely moved to device cells. New options are introduced
for exporting these cells. Tests have been updated.

Matthias Koefferlein f86f8149eb Fixed a bug that caused a segfault in the Layout2Netlist object (array repo references to original layout rather than to the working layout) 2019-01-05 22:40:53 +01:00
Matthias Koefferlein 15b79c9ddb IMPORTANT BUGFIX: array repo handling
The issue: when cloning an array, the
"in_repository" flag might be left set. This
makes the system think the array is kept in
a repo. In the best case this creates a
memory leak.

Matthias Koefferlein 9c607d7663 Added a first version of the layout to netlist extraction feature
The main entry point is RBA::LayoutToNetlist which is the
GSI binding for the layout to netlist extractor. For a first
impression about the abilities of this extractor see the
Ruby tests in testdata/ruby/dbLayoutToNetlist.rb.

The framework itself consists of many classes, specifically

- RBA::Netlist for the netlist representation
- RBA::DeviceClass and superclasses (e.g. RBA::DeviceClassResistor and
  RBA::DeviceClassMOS3Transistor) for the description of devices.
- RBA::DeviceExtractor and superclasses (i.e. RBA::DeviceExtractorMOS3Transistor or
  the generic RBA::GenericDeviceExtractor) for the implementation of the
  device extraction.
- RBA::Connectivity for the description of inter- and intra-layer connections.
