m1.5: Constraints Editor: TIMESPECs which reference other TIMESPECs are displayed incorrectly

描述

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.

解决方案

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.
