Chapter 2: Installation
Using the ISE Design Suite Installer
Before invoking the ISE® Design Suite Installer, it is a good idea to make sure that all
instances of MATLAB are closed. When all instances of MATLAB are closed, launch the
installer and follow the directions on the screen.
Choosing the MATLAB Version for a Windows OS Installation
As the last step of the System Generator Windows installation, click the check box of the
MATLAB installation you wish to associate with this verison of System Generator, then
click Apply.
If you don’t see a valid version of MATLAB listed, for example a version installed on a
network device, click the Add Version button, browse to the MATLAB root directory of the
unlisted version, then click Add. If you wish to associate this version of MATLAB with
System Generator, click the check box of the newly listed MATLAB installation, then click
Apply.
If you have no version of MATLAB available, click Choose Later to continue with the
installation. At a later time, after you have installed MATLAB, you can associate that
version of MATLAB with System Generator by executing the Windows menu item Start >
All Programs > Xilinx ISE Design Suite 12.1 > System Generator> Select MATLAB
version for Xilinx System Generator.
Post Installation Tasks
Post-Installation Tasks on Linux
After following the directions of the main ISE Design Suite Installation Wizard, you are
ready to launch System Generator by typing: sysgen
Note:
This will invoke MATLAB and dynamically add System Generator to that MATLAB session. At
the top of the MATLAB Command Window, you should see the “Installed System Generator
dynamically” messages. You are now ready to run System Generator.
The following is an expected message under certain conditions. If System Generator is
already installed when this script runs, you will see the following message:
System Generator currently found installed into matlab
default path.
Troubleshooting a Linux Installation
The following four functions are used to troubleshoot and verify the Linux Installation.
xl_get_matlab_support_xmlfile
This MATLAB function will retrieve the expected location of the common XML file
used for determining MATLAB support within System Generator.
xl_verify_matlab_support_xmlfile
This matlab function will verify that the XML file exists and is readable. If no XML file
exists, the following error message is thrown to the MATLAB console”
Could not find ml_supported.xml to determine supported versions
of MATLAB with System Generator.
