Hi all,
Do you have ever met this case?
Timing result based on RSPF file is different from that based on SDF file.
The RSPF file was extracted from post-layout database by HyperExtract. And the SDF file was converted from that RSPF file by Pearl or PKS. The design can pass STA in PKS with RSPF file but cannot pass with SDF file.
I don't know what's difference between RSPF and SDF. but it seems very strange. Do you know how Pearl/PKS converts RSPF into SDF? And what's the difference of timing calculation algorithm for RSPF and SDF in Pearl/PKS.
