The problem of NCO

[Altera_Forum]

Hi! 

I am new to the NCO. I meet some problem when I use the NCO,I want to use the NCO to generate a sinusoidal wave and a cosine wave,but the result is not right.   is anyone can suggest me?   thank you in advance!

The value for the phase increment that you input on the phi vector is wrong. It should be the value indicated by the megawizard (85899346).

I get it,thank you!

which value is entered by user?(signed or unsigned or hex .....)

I'm guessing decimal, but it is probably written somewhere in the NCO datasheet.
