Arbitrary Waveform Generator

Hi, Im trying to build an arbitrary waveform generator using the Stratix-III DSP development kit. I have been successful at outputting a sine wave using the NCO megafunction, but is there a way for m...

If you review the NCO user guide, you'll notice, that the "large ROM" implementation involves full 360° sine tables. In so far, this (and only this) NCO variant is suited to place an arbitrary function table instead of the sine. Because the NCO design is protected IP, you can't change other features than the table.

I agree with kaz and Dave, that it's easy to set up a basic NCO (phase accumulator and look-up table) on your own, but for a fixed function table, the suggested method should work.
