This document describes the instruction to demonstrate the operation of tCAMIP on Stratix 10 MX (S10MX) development board. This demonstration shows search/replace text function by using tCAMIP on S10MX board via 10 Gigabit Ethernet communication.

1 Environment Setup

To operate tCAMIP Search Replace demo, please prepare following test environment.

1) FPGA development boards (S10MX development board)

2) Test PC with 10 Gigabit Ethernet or connecting with 10 Gigabit Ethernet card.

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

4) 10Gb Ethernet cable.

5) Quartus Prime for programming FPGA, installed on Test PC

6) File “tCAMIPSearchReplacePack-S10MX.zip” that included Test Application named “SearchReplace.exe” and configuration file named “tCAMIPRef_time_limited.sof”.

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.

3 FPGA board setup

1) Make sure power switch is off and connect power supply to S10MX development board.

2) Connect USB cable between FPGA board and PC via micro-USB

3) Connect 10Gb QSFP+ connector to S10MX board.

4) Connect 10Gb 1^st SFP+ connector to Test PC.

5) Power on system.

6) Open QuartusII Programmer to program FPGA through USB-1 by following step.

a) Click “Hardware Setup…” to select “Intel Stratix 10 MX FPGA Development Kit”.

b) Click “Auto Detect” and select FPGA device.

c) Select FPGA device icon.

d) Click “Change File” button, select SOF file in pop-up window, and click “open” button

e) Check “program”

f) Click “Start” button to program FPGA and wait until Progress status is equal to 100%

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

o LED0 is turned on when hardware reset switch is push.

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.
