Verilog Ethernet Nexys Video Example Design

Introduction

This example design targets the Digilent Nexys Video FPGA board.

The design by default listens to UDP port 1234 at IP address 192.168.1.128 and will echo back any packets received. The design will also respond correctly to ARP requests.

• FPGA: XC7A200TSBG484-1
• PHY: Realtek RTL8211E

How to build

Run make to build. Ensure that the Xilinx Vivado toolchain components are in PATH.

How to test

Run make program to program the Nexys Video board with the Digilent command line tools. Then run

netcat -u 192.168.1.128 1234

to open a UDP connection to port 1234. Any text entered into netcat will be echoed back after pressing enter.

It is also possible to use hping to test the design by running

hping 192.168.1.128 -2 -p 1234 -d 1024
