I checked on the web page for the Xilinx tools and this is what I found...
"The memory requirements for both RAM and hard disk space will vary depending on your target device family and size as well as the unique characteristics of your design. "
Anyone have an idea of how much hard drive space is needed for the full toolset? I don't get why they don't provide some sort of figure either a base or a maximum. I guess if you have to ask, you don't have enough space?
