説明

General Description:

When there is a PERIOD constraint used with a FROM:FFS:TO:FFS

constraint (FROM:TO overrides PERIOD constraints where there

is overlap), and there is a path covered by FROM:FFS:TO:FFS

which is slower than the slowest path covered by the PERIOD

constraint, the minimum delay and maximum frequency is

incorrectly reported.

Instead of reporting the longest path covered by the FROM:TO

constraint, the longest path covered by the PERIOD constraint

is used instead.

This no longer happens in x1_5.18.
