Digilent JTAG-HS3 Programming Cable

Likely have bought a couple dozen of these for work. If you are using the Xilinx red or blue JTAG boxes, please stop. These work as-well (or better?), cost *much* less, are simpler to work into experimental rigs. Working on an experimental radar, so not uncommon to have JTAG into three different FPGAs over a physically large rig, and more than one test rig. Saves time ($$$) when you can leave a rig in-place, and not have to shuffle around pricey Xilinx JTAG boxes.

When I first connected the device, Vivado did not recognize it. When I checked device manager to be sure Windows recognized it as a device, I found that it showed up as a generic RS-232 device. I made sure I installed the cable drivers for Xilinx (ticking the box on the inital Vivado installer), and then I used device manager to uninstall the RS-232 device. Once windows stopped catagorizing it as an RS-232 generic adapter, The Xilinx cable driver was able to use it as a JTAG adapter. So it works, but not without some manual troubleshooting, without any documentation directly mentioning these driver problems, which to Digilent's credit, is not their fault. It works now. I hope this helps someone else wondering why the JTAG device doesn't show up at all in Vivado.

Good product

Save a lot of extra $ instead of buying the name brands to program or flash your FPGA devices, or debug. Use with Vivado tools and Xilinx UltraScale+, have had no issues.

Its exactly in the description, thank you!
