Hi, I'm trying to get SPEF for a thermal simulation. It seems that with SoC Encounter, I have to finish detailed routing then after RC extract, I can save SPEF. Can I get SPEF at earlier stage, such as after placement? If Encounter can't do that, is there any other tools can do that? What data is needed before I get SPEF and till when I can get SPEF?
Thank you!
Thank you!
