When trying to apply a Period Constraint in HDL, I find that it does not get propagated to the Timing Report and/or PCF.
How do I overcome this issue?
解决方案
This is a known issue and is scheduled to be fixed in the next major release of the software.The work-around is to apply a PERIOD Constraints in UCF.
