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.
- NetlistProperty is the base class for objects that can
be attached to shapes for annotation
- First property type implemented: net name is a way
to annotate net names
This commit adds "permissive" mode to OASIS writer to allow
odd-width paths (which are rounded).
This commit contains in addition:
* The check for odd-width paths is done post-scaling, so
reducing the DBU is a workaround
* Unit tests for the RBA binding of SaveLayoutOptions
* Documentation updates on some SaveLayoutOptions attributes
* Using Ruby predicate notation for cif_blank_separator?
(note question mark) for consistency. The old notation is
still there but deprecated
* --permissive option on buddies command lines where applicable
