JTAG Interface

The board provides a right-angle, 10-pin JTAG header. The JTAG header
protrudes through the front panel of the PCIe card, which positions it well
for internal accessibility while the box is closed. Pin 1 is located on the
side nearest the SFP connectors.

The JTAG header can be used for JTAG-based FPGA programming as
well as communication to a standard computer using a USB-Blaster
download cable. Speeds of approximately 1 Mb/s are achievable using an
SOPC Builder-based Nios II system in the FPGA (via the Quartus II
software SLDHUB primitive) and the default USB-Blaster driver that
Quartus II software installs for JTAG programming and SignalTap
debugging.
