Error (169281): There are 257 IO input pads in the design, but only 224 IO input pad locations available on the device. Tried virtual pins but it didn’t solve the problem.

What version of Quartus? What device/family? How many top level I/Os does your code define?

You need to provide a lot more info before anybody can provide any significant help.

    Thank you for replying. I was able to make changes and get the design to compile. Now I need to program the device.
