If the user-defined generated clock is unnecessary, remove the constraint and use
the auto-derived clock instead. If constraint is necessary, verify that the generated
clock constraint matches the auto-derived clock waveform or modify the GT properties to
match the expected clock waveform. If the intention is to force the name of the
auto-derived clock, the recommendation is to use the create_generated_clock constraint with only the -name option defined and the name of the object where the clock is defined
(typically output pin of GT). See the
Vivado Design Suite User Guide: Using
Constraints (UG903) for
additional information about creating generated clocks and restrictions of the
auto-derived clocks renaming constraint.
