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.
