- If the user-defined generated clock is not necessary, remove the constraint and use the auto-derived clock instead.
- If the constraint is necessary, verify that the generated clock constraint matches the auto-derived clock waveform or modify the CMB properties to match the expected waveform.
- If you only want to rename the auto-derived clock, use the
create_generated_clockconstraint with only the-nameoption defined, along with the name of the object where the clock is defined (typically the output pin of the CMB).
Refer to 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.
