I would do that but my Virtex 4 board doesn't support USB downloading. The USB cable that came with my new digilent board doesn't work at all. I have 3 digilent parallel III cables that are suppose to work at 1.5, 1.8 &
2.5v. Either these things are not tested before shipping or the design is just flat out wrong. Digilent seems to be like those chinese companies that have no idea as to what they are selling & can't provide anyone to answer the most basic question.
