The JTAG connections on the FPGA are wired directly to the expansion connector MC2 on the XEM7010 to facilitate FPGA configuration and ChipScope usage using a Xilinx JTAG cable. The JTAG interface presented at MC2 is a 3.3v interface corresponding to the FPGA JTAG I/O voltage. An appropriate connector (such as a 2mm connector compatible with the Xilinx JTAG cable) would need to be wired on the peripheral attached to the XEM7010. Our BRK7010 has this connector and may be used as a reference.
See the pins sheet for a list of the JTAG pin connections.
