Xilinx ise in Papilio Pro Posted December 24, 2017 · Report reply xilinx ise. What a whopper of a file and a nightmare to get hold off? Im on the second download as origonal thinks its a 1.8Tbyte file!? If its free software and this large and crucial to papillio. Why wasn't it put on a disc and shipped with it? Ive been waiting a long time to get a PRO and when i saw the availability i treated myself for christmas! Just getting bogged down with getting it going.
