Hi,
I was doing psynopt command using ICC and when the last stage of optimization had completed the log showed something like this:
Then I checked the QOR using report_qor command and the last few lines of the report are listed below:
Number of violating paths for setup timing on the log is different compared to the report_qor command. I previously never encountered something like this; usually the number always the same. Can anybody explain to me why this happened?
Thanks a lot!

Antonius
