14.x Timing Analyzer - Why is skew reported between two unrelated clocks?

Description

Why is skew reported between two unrelated clocks for a FROM/TO constraint or a functionally similar constraint?

Solution

Timing Analyzer reports the skew between two clocks even if the clocks are unrelated.

If the clocks are unrelated, you can use the DATAPATHONLY keyword for the FROM:TO constraints because it ignores the clock skew.
