Looks like they have some legal stuff pertaining to using the software....
By installing the software onto your PC you are bound to the license agreement of the Arrow
USB-Blaster software. The complete license agreement can be found in chapter 5, License
Agreement on page 7. This license agreement, in short, allows you to use the software only in
conjunction with Altera FPGA purchased or obtained in any other legal way from Arrow or a subsidiary of Arrow.
So if I used their design and bought the fpga that I was using from them I guess I could make a board and use their software...correct me if I am wrong here.
