how to input an external clock source on DE0 board

I want to input an external 8MHZ clock source to the DE0 FPGA poard, but the DE0 board doesn't have the external clock pin for this. Can I use any other pin or method to realsise this? Thank you for ...

So for example, I can just connect the external clock source to the pin1 (GPIO0_CLKIN0) in GPIO 0, and assign the clock signal in FPGA to AB12, then the clock frequency of CPU core will become 8MHZ? Is it correct? Thank you for your reply.
