Q: What is the difference between the "XUP USB-JTAG Programming Cable" and the "Xilinx HW-USB-II-G"?

Digilent XUP USB-JTAG cable is based directly on Xilinx HW-USB-G design. They are functionally the same. Xilinx tools treat them like the same cable and they have practically identical performance benchmarks.

Xilinx advertises the HW-USB-II-G as being

  • faster than the HW-USB-G
  • able to program compatible FPGAs with an encryption key for use with encrypted bitstreams

We have not noticed a speed difference between the Xilinx HW-USB-II-G and the Digilent XUP USB-JTAG cable. The ability to program with encryption keys is one feature the Digilent XUP USB-JTAG cable doesn't have. However most customers don't use this feature.
