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.
