Problem Title:
M1.5i/2.1i; Timing: PERIOD constraint analyzes path from a FROM:THRU:TO spec
Problem Description:
Urgency: Standard
General Description:
In some PCI designs the user may experience the following:
PERIOD constraint analyzes a path from a FROM:THRU:TO spec.
even though the path was put in a group and the group was used
in the THRU.
Solution 1:
The problem is due to a multiple constraint interaction. The design
may have many more specs than are necessary and it may be
possible to reduce the number of specs and be more selective
and specific with the necessary ones to eliminate the problem.
