The good news: ISE 14.7 offers a free WebPACK license for many Spartan-6 devices. For larger Virtex-6 parts, you will need a paid license file (which AMD still supports generating for existing customers via the licensing portal).
If you try to run it on modern Windows, you will face the infamous "Ning" (libPortability) errors or driver issues with the cable drivers. To get it working today, you have two options: xilinx ise 14.7 download
