CadenceTM Compatibility
Xic has a limited capability for compatibility with Cadence
VirtuosoTN technology, display resource (DRF), and layer mapping
files. For export to a Cadence environment, the !dumpcds
command will create compatible technology and DRF files based on the
Xic technology file in use.
Import from a Cadence environment is handled by two keywords which
can be used in the Xic technology file. In fact, a minimal
technology file can consist of little more than these keywords.
- ReadCds filename
The filename is a path to a Virtuoso ascii technology file or
display resource file. This keyword can appear anywhere int the
Xic technology file. Typically, the keyword will appear twice,
once for each type of file. In this case, the display resource file
must be imported first.
- ReadCdsLmap filename
The filename is the path to a Virtuoso layer mapping file.
This provides GDSII layer/datatype numbers for the layers. This must
appear in the Xic technology file after ReadCds.
Presently only drawing layers are imported.
