Simple 8bit DeltaSigma DAC. (altera forum is my inspiration)
Did you ever try to open your zipped project on a different computer?
I tried with two of your uploaded project and there are obviously some files missing.
I´m trying this file and working. This is not complete project this is only component. Please try import component to new project.
Ah, I see. But there is a forum for community components where your work would be better hosted together with a little bit of documentation.
