Arbitrary Waveform Generator

I don't want to sound like a n00b, but ..... that seems like alot more work that what I want to do.

I didn't mention that this is just a quick and dirty project, it doesn't need to be the "correct" method, just the fast way.

Anyway, I wrote up a sinewave in matlab, and got it recognized by the NCO at compile time. It works.....except for the fact that it "overlaps" on itself every few clock periods. It seems that the NCO is looking for a file a certain size, not sure though.

This is slightly off topic, but lastly, I heard that some higher-speed DACs don't like it when they are told to hold a value for a constant amount of time, ie, put out a pulse with a really long period. Is this true? Has anyone heard of this? The Terasic DAC/ADC board manual doesn't indicate this so I'm a little confused. In the future I will like to create a ROM that is filled with values for a Pulse.

Thanks
