Hello everybody
Is adding clock uncertainty in TimeQuest a good idea when timing analysis says that everything is OK but the Design still does not operate correctly? Can clock uncertainty lead to a more robust fitting result or a more pessimistic timing analysis?

Hi Stefan,
with uncertaincy setting you define a kind of "guard band" when performing the setup and hold checks. It represents the influence of jitter or clock skew.
Is your design full constrainted ? TimeQuest reports all unconstraints input and output ports. Could be found in the folder "Diagnostic"
Kind regards
