NCO 8.1 Problem

HI, no matter what output freq. I set my NCO to have it is always coming out at 20 Mhz, or this is what I am measuring on the scope. I don't think this was happening when i was using quartus 6....

Hi, so for example for a freq. of 10MHz the phase value comes to 429496730, I just convert this to a binary number and use it as the input as v and g's yea?

I didn't realise that it was this input that actaully generated the freq.

Cheers
