* First implementation.
* PORT BACK: fixed a few flaws (fixed-width side panel ..)
1. On "save as" the filename displayed in the cell view selection box
was not updated
2. The width of the library and cellview panel could not be reduced
below the width of the combo boxes in the headers. So the
panels might have become pretty wide without being able to reduce
them.
* Implemented #560 (multiple techs on libraries)
Because long is 32bit on Windows (like int), the
conversion from long to unsigned int was subject
to sign overflow. This was fixed by going to
unsigned int via unsigned long.
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
