Multiple clocks are user generated or auto-derived on the source pin(s) <pin_names>
but are not logically or physically
exclusive with respect to one another. To have the static timing analysis match the
behavior in hardware, there cannot be multiple clocks generated on the same pin(s). In
such cases, the clocks should be defined as physically or logically exclusive. The list
of clocks generated on the source pin(s) is: <clock_names>
