Is R_lib necessary for corner analysis?
I dont have RF_lib.. How can I download that RF_lib? Is is freely available.... or I need to purchase it....
I don't know what "R_lib" or "RF_lib" are, but they're not needed for corner analysis. If you're talking about "rfLib" (which is a Cadence-supplied example library, which also is not needed for corner analysis), it is in your IC installation - you can put this into your cds.lib file:
DEFINE rfLib $(inst_root_with:tools/dfII/bin/virtuoso)/tools/dfII/samples/artist/rfLib
Or if using IC5141:
DEFINE rfLib $(inst_root_with:tools/dfII/bin/icfb)/tools/dfII/samples/artist/rfLib
