Dear all,
I have a DRC-clean design on Innovus (verified by the Innovus tool: Verify -> Verify DRC). However, when I extract the GDS and import it into Calibre, hundreds of errors are highlighted! Calibre uses a separate DRC_rule_file which, I think, Innovus has no access to.
I guess Innovus only uses the rules in the .LEF files to generate and verify the layout, am I right?
Is it possible to feed the DRC_rule_file (what Calibre reads) to Innouvs so the generated layout meets those rules?
Should I trust Innovus and go ahead with the current design?
Could it be an issue with generating the GDS file?
Many thanks,
Anas
