Verilog Ethernet KC705 Example Design
Introduction
This example design targets the Xilinx KC705 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.
Configure the PHY for SGMII by placing J29 and J30 across pins 2 and 3 and opening J64.
- FPGA: XC7K325T-2FFG900C
- PHY: Marvell 88E1111
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 KC705 board with Vivado. 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
