8.1 System Generator for DSP - Why is my old System Generator for DSP missing, or has disappeared when running xlVersion after installing a new version like 8.1 or 8.2?

Description

Why is my old System Generator for DSP missing, or has disappeared when running xlVersion after installing a new version like 8.1 or 8.2?

Solution

This is a known issue on some installs where the file that stores the installed versions for System Generator for DSP is marked as Read Only during the install. You can work around this issue by doing the following:

1. Open Windows Explorer and navigate to:

C:\MATLAB704\toolbox\xilinx\sysgen\util\instlist.txt

2. Right-click on the "instlist.txt" file and uncheck the Read-only attribute.

3. Run "xlVersion -add {path}" command to add the old version of System Generator for DSP

e.g., xlVersion -add C:\MATLAB704\toolbox\xilinx

NOTE: If you point to a path that is not valid, xlVersion will produce an error and not add the path to the "instlist.txt" file.
