Hi all!

I performed timing analysis in PT DMSA and have found that my "clock reconvergence pessimism" in report is 0 (crpr analysis is active), but my timing path has common clock path and CRPR value should be non-zero. I used "report_crpr" command on this path, results are presented below:

As seen, we have difference btw actual and reported in the timing report values (UITE-468 message). I tried to reduce "CRPR_threshold" value from this report ( by seting " timing_crpr_threshold_ps" command), but it does not work, I can only increase "CRPR threshold" value, but not decrease. The question is - how I can set this CRPR Threshold value and make CRP value from this report and from "report_timing" equal?
 

The problem is solved by updating PT tool.
