10/13/2022, 11:22 AMThere is one SDF file in the project directory. I assume it is generated by the sta.tcl script.
Which process corner is it based on ?
How do I generate SDF files for the other process corners ?
Where can I find the parameters of the process corners ?
Thanks in advance for an answer that really helps.
Cheers, Tobias

Besides that, the ss,tt,ff SDFs are generated by the Caravel framework by default - using the latest and greatest OL - as well, right ? Or do I have to set additional flags ?
