write_parasitics -format spef
Excuse me, can anyone help me ? The problem is i have designed a quite large design contains 4 generation : grand_father, father,son and grand_son. After design i have annotated the parasitics elements and RC trees through the : write_parasitics command directly with the highest level grand_father( or in other word TOP Module) design. But after annotating it my SPEF file has been rejected by both PrimePower and PrimeTime due to the tool cant find some branches in the SPEF file. What should i do ? Plz give me some advise as soon as possible. Thanks alot.
