Our lab has many USRP2s and try to modify the FPGA code enabling CSMA/CA
on the board. We learn that the UHD FPGA code can be compiled with
Xilinx ISE 12.x. What about the most recent version of Xilinx tool,
We need to purchase the Xilinx tool, but want to make sure that the FPGA
code can be compiled with 14.x without buggy output.
