DE2 clock multiplier megafunction

[amoghsimha]

Hi. I want to achieve a clock frequency of 20MHz for my program to be implemented on the DE2 kit. I got the idea that I can multiply the 50Mhz clock by 2 and then divide it by 5. Is there a megafunction that multiplies the clock frequency or something?
Or is there any other way to obtain a 20MHz clock? Thank you.

use a ALTPLL (Phase lock loop) megafunction
