## Overview

The Digilent JTAG-HS3 is a compact, high-speed USB2 programming and debugging cable designed specifically for Xilinx FPGAs and SoCs. Featuring a direct 2x7 JTAG header connection, a 30 Mbit/sec adjustable data rate, and an open-drain buffer on pin 14 for advanced SoC debugging, it offers a cost-effective, reliable alternative to pricier Xilinx boxes. Powered via USB Micro-B, it integrates seamlessly with all Xilinx tools, making it an essential tool for professional FPGA developers and experimental rig setups.

## Description

The JTAG-HS3 is an affordable high-speed Xilinx FPGA programming solutions. The HS3 builds on the successful JTAG-HS1 by adding an open-drain buffer to pin 14 allowing for the debugging of Xilinx Zynq-SOC processors. It can be attached to target boards using Xilinx's 2x7 connector*, and is compatible with all Xilinx tools, including iMPACT, ChipScope, and EDK. When connected to a PC via a standard A to micro-USB cable, the JTAG HS3 receives its power from USB and can be recognized as a Digilent programming cable, even if the HS3 is not attached to the target board. The JTAG bus can be shared with other devices as the HS3's signals are held in high-impedance, except when actively driven during programming. The HS3 is small and light, allowing it to be held firmly in place by the system board connector. * This is a unique programming header and is not compatible with the 1x6 MTE Digilent JTAG Connector.

Review: 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.
Review: 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.

## Questions & Answers

**Q: Does this cable support ultrascale+ (16nm) xilinx devices including the mpsoc?**
A: The version of Vivado is what determines device support, not the cable.  The cable works for me in Vivado 2019.1 and beyond.
