This document describes the instruction to demonstrate the operation of tCAMIP on Kintex UltraScale+ (KCU116) development board. This demonstration shows search/replace text function by using tCAMIP on KCU116 board via 10 Gigabit Ethernet communication.

1 Environment Setup

To operate tCAMIP demo, please prepare following test environment.

1) FPGA development boards (KCU116 development board)

2) Test PC with 10 Gigabit Ethernet card.

3) Micro USB cable for JTAG connection between FPGA development board and Test PC

4) 10Gb Ethernet cable (SFP+ to SFP+).

5) Vivado Hardware Manager for programming FPGA, installed on Test PC

6) File “tCAMIPSearchReplacePack-KCU116.zip” that included Test Application named “tCAMIP Search Replace” and configuration file named “tCAMIPRef+.bit”.

2 PC Setup

Before running demo, please check the network setting on PC. Ethernet setting is shown as follows.

2.1 IP Setting

Figure 2‑1 Setting IP address for PC

1) Open Local Area Connection Properties of 10-Gb connection, as shown in the left window of Figure 2‑1.

2) Select “TCP/IPv4” and then click Properties.

3) Set IP address = 192.168.7.81 and Subnet mask = 255.255.255.0, as shown in the right window of Figure 2‑1.

2.2 Speed and Frame Setting

Figure 2‑2 Set frame size = jumbo frame

1) On Local Area Connection Properties window, click “Configure” as shown in Figure 2‑2.

2) On Advanced Tab, select “Jumbo Packet”. Set Value to “9014 Bytes” for Jumbo Frame support or set value to “Disabled” for non-Jumbo Frame support, as shown in the bottom window of Figure 2‑2.

3) On Link Speed, select “10 Gbps Full Duplex” for running 10-Gigabit transfer test, as shown in Figure 2‑3.

Figure 2‑3 Set link speed = 10 Gbps

4) On PROSet Advanced Tab, select “Performance Options” and click “Properties” button.

5) Set “Interrupt Moderation Rate” = OFF.

4) Power on system.

5) Open Vivado Hardware Manager to program FPGA by following step.

a) Click “Auto Connect” to connect with board.

b) Right click at “xcku5p_0”, then select “Program device …”

c) Select “.bit” for configuration bit file.

d) Select “.ltx” for debug probe file.

e) Press “Program” button to program device.

6) When configuration is completed, user can check status LEDs on board as Figure 3‑4.

o LED0 is always blink to show clock is working.

o LED1 is turned on when TOE10GIP is ready for data transfer.

o LED2 is turned on when tCAMIP is initialized successfully.

o LED3 is turned on when software open connection to S10MX board.
