Well, I do believe there is some sort of differential signalling that the Xilinx can do, but I'm not sure. At the very least, you could code your logic so that it drove pairs of pins in antiphase. But I'm not sure if that'll solve the problem or not. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
