8 years agoThis means Quartus does not think it needs your 'CLK' signal to implement your design, which means you're not using it as you thought you were.
Once you've corrected this error, use the 'Pin Planner' - under the 'Assignments' menu in Quartus - to assign your I/O signal to the pins you want. Cheers, Alex
