-The NetFPGA-1G has two 12-pin connectors to support I/O expansion via Digilent Pmods. Digilent manufactures Pmod accessories that support a large variety of external interfaces that increase system flexibility. The Pmod connectors are 2x6 right-angle 100-mil female connectors that work with the standard 2x6 headers available from a variety of distributors. On the NetFPGA-1G, each 12-pin Pmod connector provides two 3.3V VCC supply connections (pins 6 and 12), two Ground connections (pins 5 and 11), and eight logic signals (Fig. 2). The supply pins can provide up to 1A of current to connected Pmod devices. The logic signals are not matched pairs. They are routed without impedance control or delay matching. Note also that the connectors are not keyed, so care should be taken to verify that any connected devices have Pin 1 aligned with Pin 1 on the connector. Pin 1, VCC, and GND are clearly labeled on the PCB to help simplify proper connection.   +The NetFPGA-1G has two 12-pin ports to support I/O expansion via Digilent Pmods.

    - Plug the NetFPGA-7 into the HTG PCIe test card. Loop the RX0-3 pairs on the HTG card to the TX0-4 pairs using SMA cables (RX0P <-> TX0P, RX0N <-> TX0N, etc.). Set switches 1-3 on the HTG card to 000. Additionally, power the HTG card with a Molex connector from a standard PC power supply, and ensure the power switch is set to ATX     - Plug the NetFPGA-7 into the HTG PCIe test card.

 Many tests can be run independently without the need for additional hardware. For example, the HiTech Global Breakout Board is only needed to test the PCIe edge connector. More details regarding individual tests are provided in the //NetFPGA-1G Manufacturing Test Reference Manual// available on the Digilent web site. Many tests can be run independently without the need for additional hardware.
