ID:268015 No node assigned as clock signal -- pin generated for clock signal

CAUSE: You tried to run the Signal Tap Logic Analyzer, save the Signal Tap File (.stp), or use the Save To Data Log command (Edit menu). However, you did not assign a clock signal to a node. As a result, the Quartus Prime software generated a pin which you can assign to a clock.

ACTION: Click OK to close the message dialog box. Use the Signal Tap: pre-synthesis filter in the Node Finder to search for a valid clock signal, or assign the pin the Quartus Prime software generated to a clock.
