So I'm currently trying to synthesize a design and apparently it's too big to compile or something. It compiles and simulates perfectly in ModelSim, but in quartus throws this error:

Error: Design requires 491 I/O resources -- too many to fit in 456 available in the selected device or any device in the device family

Apparently I have 491 I/O resources but can only fit 456 (??). I have no idea what that means or how to extend the 456 number. Google searching gets me nowhere. Does anybody know what to do in this case?

Thanks a lot!
