Honored ContributorCLKIN Pin as General Purpose Input
I'm doing a Cyclone III design (simulation only, no hardware yet) and am using one of the dedicated clock input pins as a general purpose input. It compiles OK & meets timing constraints so I'm assu...

Honored ContributorJust to add on, you can use Quartus II Fitter compilation to verify if a specific pin usage can be implemented on the device. Fitter will help to check against the placement rule and any violation. You should also do a functional simulation with your design to check on the behavior to your expectation.
