1. If the violation refers to a user-defined clock, remove the create_clock constraint on the output of the CMB.
2. If you want to force the name of the auto-generated clock, use the create_generated_clock constraint with only the -name option and the CMB output pin.
3. If the clock is generated by the Clocking Wizard, verify the setting in the Input Clock Information > Primary Input Clock menu:
   • Use Single ended clock enabled pin when the input clock is directly connected to a top-level I/O port.
   • Use Global Buffer when the input clock comes from another Clocking Wizard instance.

Refer to the Vivado Design Suite User Guide: Using Constraints (UG903) for additional information about creating generated clocks.
