If the user-generated clock constraint is unnecessary, remove it and use the
auto-derived clock instead. If the constraint is required, verify that it matches the
auto-derived clock waveform or adjust the GT properties to match the expected clock
waveform. To only rename the auto-derived clock, use the create_generated_clock constraint with the -name option and the GT output pin. For more information about creating
generated clocks and restrictions on renaming auto-derived clocks, refer to the
Vivado Design Suite User Guide: Using
Constraints (UG903).
