NetFPGA-1G-CML™ Board Reference Manual

Overview

The NetFPGA-1G-CML is a versatile, low cost network hardware development platform featuring a Xilinx® Kintex®-
7 XC7K325T FPGA and 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. The FMC connector can also be used to extend functionality via a wide variety of
other cards designed for communication, measurement, and control.

The NetFPGA-1G-CML is designed to support the Stanford NetFPGA architecture with reference designs available
through the NetFPGA GitHub Organization (www.github.com/organizations/NetFPGA). It is fully compatible with
Xilinx Vivado™ and ISE® Design Suites as well as the Xilinx SDK for embedded software design.
