14.2 Timing Analysis - Increase in Timing Score due to Clock Uncertainty change
描述
I ran timing analysis on my 14.1 design and noticed that my Timing Score had changed. This change was due to a change in the Clock Uncertainty value. Is this change expected?
解决方案
The timing engine had an issue of incorrect calculation inclock uncertainty value in the timing report. This issue was fixed in 14.2. The correct clock uncertainty is being calculated in 14.2 and beyond.
