Re: [Discuss-gnuradio] problem of compiling FPGA bin files.

[Matt Ettus]

Some people have had success with ISE 11.1, and some have not.  I have
not tried it yet, and am still on 10.1.03 which is known to work.  Early
in the new year I'll be moving to 11.1, but if anyone can figure out the
problems, that would be much appreciated.
