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....

Exactly!

You could also use the Altera lpm_constant function to get the value correctly and connect it to the NCO phi_inc_i input
