Chapter 3: Using Hardware Co-Simulation
Load the Sysgen Spartan-3A DSP 3400A HW Co-Sim Configuration Files
System Generator comes with HW Co-Sim configuration files that first need to be loaded into the Spartan-3A DSP 3400A CompactFlash card with a CompactFlash Reader.
1.
Optionally Backup the Spartan-3A DSP 3400A Demo Files
The Spartan-3A DSP 3400A CompactFlash card comes with a series of demo files that you might want to re-load and exercise later. a.
Connect the CompactFlash Reader to the PC. This is usually done through a USB port.
b. Insert the CompactFlash card into a CompactFlash Reader. c.
Click on the MyComputer icon, then select the Removable Disk drive that represents the CompactFlash Reader..
d. Create or open a backup folder on the PC and copy the content of the
CompactFlash card to that folder for later use.
Note:
For the following steps, 'e:' is assumed to be the drive name associated with the
CompactFlash reader.
2.
Re-Format the CompactFlash Card
The card needs to be re-formatted to a FAT16 file system before the System Generator files can be transferred. You use the mkdosfs utility to format the card. a.
Download the mkdosfs program from the Xilinx URL address: http://www.xilinx.com/products/boards/ml310/current/utilities/mkdosfs.zip.
b. Extract to folder C:/mkdosfs c.
Open a Windows shell by selecting Start > Run..., then type cmd in the Run dialog box and click OK.
d. In the shell, move to the mkdosfs folder: cd C:\mkdosfs
Caution!
In the following step, make sure the drive name (e.g., 'e:' in this case) is specified correctly for the Compact Flash Removable Disk. Otherwise, the information on the mistakenly targeted drive will be erased and the drive will be re-formatted.
e.
Type the following mkdosfs command after the Windows command prompt: mkdosfs -v -F 16 e:
The content of the Compact Flash card should be wiped clean and re-formatted.
3.
Copy the Sysgen configuration files to the Compact Flash card
Note:
For reference, the Sysgen files to be copied are located at the following pathname:
...<sysgen_tree>\plugins\bin\S3ADSP_DB_sysace_cf.zip
Invoke MATLAB on the PC, then enter the following command on the MATLAB
Command Line: unzip(fullfile(xlFindSysgenRoot,'plugins/bin/S3ADSP_DB_sysace_cf.zip'),'e:/')
Optional Step to set the Ethernet MAC Address and the IPv4 Address
Note:
The following step may be necessary if the default MAC and IP addresses conflict with your default network settings, or if you wish to co-simulate two or more ML506 platforms concurrently. If not, proceed to the next topic.
After writing the data to the card, you will find two files, mac.dat and ip.dat, in the card root directory. The mac.dat and ip.dat files specify the Ethernet MAC address

Installing Your Hardware Co-Simulation Board
and IPv4 address associated with the platform, respectively. These addresses are used to uniquely identify a target platform during Ethernet hardware co-simulation. a.
Open mac.dat in a text editor and change the Ethernet MAC address. The MAC address must be specified as a six pair of two-digit hexadecimal separated by colons (e.g. 00:0a:35:11:22:33). All-zeros, broadcast, or multicast MAC addresses are not supported. a.
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 ML506 platform, update the IP address for the network connection on the PC accordingly as mentioned in the topic
Setup the Local Area
Network on the PC
. For direct connection, the ML506 and the PC must be on the same subnet. Otherwise, the ML506 IP address should be reachable from the PC and vice versa.

4.
Remove the CompactFlash card from the CompactFlash Reader.
5.
Locate the CompactFlash card slot (on the back side of the Spartan-3A 3400A platform) and carefully insert the CompactFlash card with its front label facing away from the platform. The figure below shows the back side of a platform with the ConpactFlash card properly inserted.
Note:
The CompactFlash card provided with your platform might differ.
Caution!
Be careful when inserting or removing the CompactFlash card from the slot. Do not force it.
6.
If you are using a “Rev C” 3400A Development Platform, plug the +12V power supply adapter cable into the power connector. Plug in the power supply into AC power.
If you are using a “Rev D” 3400A Development Platform, plug the +5V power supply adapter cable into the power connector. Plug in the power supply into AC power.
Caution!
Make sure you use an appropriate power supply with the correct voltage and power ratings.
7.
Using the RJ45 Male/Male Ethernet Cable, connect the Ethernet connector on the
Spartan-3A 3400A platform directly to the Ethernet connector on the host PC.

8.
Set the S2 Configuration Address DIP Switches as follows:
1:off, 2:on, 3:off, 4:on, 5:off, 6:on, 7:on, 8:off
9.
Set the Ethernet Mode Select jumper JP2 to pin 1 and pin 2 (the default GMII).
10. Verify the Configuration Settings a.
Turn the target platform Power switch ON. b. As shown below, check the information displayed on the 16-character 2-line LCD screen of the platform. If no error occurred, the Ethernet MAC address (without colons) should appear on the first line of the display and the IPv4 address should appear on the second line.
c.
If the LCD display does not show the information correctly, press the System
ACE™ Reset button to reconfigure the FPGA.
11. Verify the Ethernet Interface and Connection Status a.
To ensure the platform is reachable by the host, issue ICMP ping from the host to check the connectivity. For example, type "ping 192.168.8.1" on a console to test the connectivity to a platform with IP address 192.168.8.1.
268
b. The target FPGA listens on the UDP port 9999. Please ensure the underlying network does not block the associated traffic when network-based Ethernet configuration is used. This does not affect point-to-point Ethernet configuration.
