Verilog Ethernet DE2-115 Example Design

Introduction

This example design targets the Terasic DE2-115 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: EP4CE115F29C7
• PHY: Marvell Alaska 88E1111

How to build

Run make to build. Ensure that the Altera Quartus toolchain components are in PATH.

How to test

Run make program to program the board with the Altera software. 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
