The NetFPGA-1G-CML is a versatile, low cost network hardware development platform featuring a Xilinx® Kintex®-7 XC7K325T-1FFG676 FPGA.

It includes four Ethernet interfaces capable of negotiating up to 1 GB/s connections. 512 MB of 800 MHz DDR3 can support high-throughput packet buffering while 4.5 MB of QDRII+ can maintain low-latency access to high demand data, like routing tables. Rapid boot configuration is supported by a 128 MB BPI Flash, which is also available for non-volatile storage applications. The standard PCIe form factor supports high-speed x4 Gen 2 interfacing. The FMC carrier connector provides a convenient expansion interface for extending card functionality via Select I/O and GTX serial interfaces. The FMC connector can support SATA-II data rates for network storage applications, and can also be used to extend functionality via a wide variety of other cards designed for communication, measurement, and control.

The powerful Kintex-7 XC7K325T-1FFG676 FPGA will have no trouble keeping up with your designs made in Vivado Design Suite or ISE.

The NetFPGA-1G-CML is not designed by Digilent. It is designed to support the Stanford NetFPGA architecture with reference designs available through the NetFPGA GitHub Organization.

    USBUART and PHY works pretty well.

    Posted by Digilent Customer on 27th Nov 2017

    So those are the only two components I have tested. Please take care that version is in has a mistake. Pins assigned to PHY1 are actually assigned to PHY3. The one in the schematics is correct

    Great FPGA board for network tests

    Posted by Sven Meier on 18th Jul 2016

    It is a great board for network tests, FPGA has plenty of space for fast development when resources shall not be the limiting factor. The PHY on the other hand is not a very sophisticated one, RGMII timings are not configurable via MDIO. Also one row of pinheaders like on the Arty would have been nice so you don't need an FMC or PMOD extension
