Hello,

I have different spef files for different RC corners. I want to do timing analysis of all the RC corners in a single PT session. So if i read all the .spef files then Is it will take last one or all? please suggest ASAP..

It will take the first one and ignore all other files. I would suggest you to run parallel runs to go ahead with your experiment. You can also use "remove_annotated_parasitcs" to remove the parasitics
