Overview
The joint test action group (JTAG)-HS1 programming cable is a high-speed programming solution for Xilinx field-
programmable gate arrays (FPGAs). It is fully compatible will all Xilinx tools, and can be seamlessly driven from
iMPACT, Chipscope™, and EDK. The HS1 attaches to target boards using Digilent's 6-pin, 100-mil spaced
programming header, or Xilinx's 2x7, 2mm connector (using the included adaptor).
The JTAG-HS1 is powered from a PC's USB port, and will be recognized as a Digilent programming cable when
connected to a PC, whether or not it is attached to the target board. A separate Vdd pin is provided on the HS1 to
supply JTAG signal buffers. The high speed, 24mA, three-state buffers allow target boards to drive the HS1 with
signal voltages from 1.8V to 5V, with bus speeds of up to 30MBit/sec. The HS1's Vdd pin must be tied to the same
voltage supply that drives the JTAG port on the FPGA (see Fig. 1).
JTAG signals are held in high-impedance except when actively driven during programming, so the JTAG bus can be
shared with other devices. The HS1 uses a standard Type-A to Micro-USB cable (included with the HS1) that
attaches to the end of the module opposite the system board connector. The HS1 is small and light, allowing it to
be held firmly in place by the system board connector (see Fig. 2).
