The JTAG connections on the FPGA are wired directly to a dedicated 2mm header (J3) compatible with the Xilinx JTAG cable. The JTAG interface presented is a 1.8v interface corresponding to the FPGA JTAG I/O voltage.

JTAG Cables

The USB interface on FrontPanel-enabled devices provides FrontPanel-based FPGA configuration and communication only. This interface is not available for JTAG access and is not compatible with the vendor tools for JTAG communication (i.e. Xilinx Vivado Integrated Logic Analyzer).

A vendor-supported JTAG cable is required to interface with the JTAG connector and provide tool access to JTAG. The following JTAG cables are available with connectors compatible with the connector on the breakout board:
