Violations of this rule identify clock pairs which are missing constraints. (1) Two generated clocks on a LUT output are missing a logically exclusive clock group assignment. (2) Two clocks pass through a LUT are missing generated clocks on the LUT output and a logically exclusive clock group assignment on the generated clocks.

Add create_generated_clock assignments on the LUT output and a set_clock_group -logically_exclusive assignment on the generated clocks.
