14.1 Timing Analyzer - Timing report does not reflect that phase shifts for the DCM
Description
When I change the phase shift numbers for the Digital Clock Manager (DCM), I do not see the change in numbers for the setup and hold calculations for the clock.
Why does this not change?
Solution
If you are doing timing analysis against auto generated constraints, phase shift numbers are not part of the timing analysis.
When you do the analysis with the timing constraints for the design, then the phase shift numbers are taken into consideration when doing the timing analysis.
