General Description: If the following constraints are read into Constraints Editor:
TIMESPEC TSMASTER=FROM:TG_MASTERCLK:TO:FFS:12.3ns
TIMESPEC TSFASTEXCEPT=FROM:FFS:THRU:FASTSIG:TOFFS:TSMASTER;
CE is displays the constraint as:
TIMESPEC TSMASTER=FROM:TG_MASTERCLK:TO:FFS:12.3ns
TIMESPEC TSFASTEXCEPT=FROM:FFS:THRU:FASTSIG:TOFFS:0.0;
This is incorrect.
The solution is to modify the constraint using the Constraints Editor or hand edit
the ucf file. This issue will be addressed in the next software release.
