Installing Your Board for Ethernet Hardware Co-Simulation
b. Open ip.dat in a text editor and change the IP address. The IP address must be
specified in IPv4 dotted decimal notation (e.g. 192.168.8.1). All-zeros,
broadcast, multicast, or loop-back IP address are not supported. After changing
the IP address for the board, update the IP address for the network connection on
the PC accordingly as mentioned in topic Setting Up the Local Area Network on
the PC. For a direct connection, the board and the PC must be on the same subnet.
Otherwise, the board IP address should be reachable from the PC and vice versa.
Installing the Proxy Executable for Linux Users
Running hardware co-simulation on a Linux machine requires that you first run a shell
script that installs a proxy executable. Do the following:
1. Log into the root account on your Linux machine
2. Go to the bin directory where System Generator is installed. For example,
cd $XILINX_DSP/sysgen/bin
3. Run the shell script called install_pcap_proxy.sh. For example, at the shell command
line type:
./install_pcap_proxy.sh
Installing an ML402 Board for Ethernet Hardware Co-Simulation
The following procedure describes how to install and configure the hardware and software
required to run Ethernet Hardware Co-Simulation on an ML402 board.
Assemble the Required Hardware
1. Xilinx Virtex®-4 SX ML402 board which includes the following:
a. Virtex®-4 ML402 board
b. 5V Power Supply bundled with the ML402 Kit
c. CompactFlash Card
2. You also need the following items on hand:
a. Ethernet network Interface Card (NIC) for the host PC.
b. Ethernet RJ45 Male/Male cable. (May be a Network or Crossover cable.)
c. CompactFlash Reader for the PC.
Setup the PC
1. Install the related software on the PC as described in the topic Installing Software on
the Host PC.
2. Setup the Local Area Network as described in the topic Setting Up the Local Area
Network on the PC.
Load the Sysgen ML402 HW Co-Sim Configuration Files
System Generator comes with HW Co-Sim configuration files that first need to be loaded
into the ML402 CompactFlash card. Follow the instructions that are described in the topic
Loading the Sysgen HW Co-Sim Configuration Files.
