CAUSE: In a Boolean expression in a Text Design File (.tdf), you used both a comparator and a constant with the specified don't care (X) value. However, you cannot use don't care values in a Boolean expression that contains a comparator. Analysis & Synthesis ignored the don't care value as it performed the comparison, and may therefore have produced incorrect comparison results.
ACTION: To avoid receiving incorrect comparison results, use only fully defined values (that is, values without don't care bits) in the comparison.
