ID:268021 Cannot define signal "<name>" as both clock signal and Signal Tap signal -- removing duplicate

CAUSE: You attempted to define the specified signal as both a clock signal and a Signal Tap signal. However, the Signal Tap Logic Analyzer cannot assign the same signal as a clock signal and a Signal Tap signal. As a result, the Quartus Prime software is removing the duplicate signal name.

ACTION: Click OK to close the message dialog box, and assign a unique signal name as the clock signal or Signal Tap signal.
