Hi folks,
I am trying to do PnR using UMC 130nm (PDK by Faraday) and Innovus by Cadence. I cannot do non-default routing rules and/or RC extraction be cause I cannot generate proper capTable files for various RC corners.
I am using generateCapTbl command, tech header LEF file and Intercap models provided by the foundry (plain text file containing some cap data), but the tool says I should not use such an old format and should not use such an old capTable. Indeed, the tool crashes whenever I try to route the design using NDR or extract the parasitics using the generated capTbl. the only option for me is to omit the captables in MMMC definitions and route the design with gross inaccuracy and default routing rules.
Has anyone come across this issue? I do not have too much experience with such an old PDK. I worked with 28nm and 16nm with QRC tech files....
Thanks shlooky.
