The problem results from a combination of issues. The Windows command prompt is limited to about 256 characters for a path name. This is a problem because during the generation of a design that uses IP cores, the internally-generated names and directories become quite large and can exceed the Windows maximum.
System Generator for DSP 11.2 and laterStarting in System Generator for DSP 11.2, CORE Generator IP cores will be generated in a temporary location. To see the temporary location where files are being generated (in 11.2 or later), type the following at the MATLAB prompt:
>> getenv('temp')
and
>> getenv('tmp')
It is possible that you will need to shorten the length of your temporary path to avoid this issue. To update this path, modify your TEMP and TMP environment variables to point to a new location such as "C:\temp".
System Generator for DSP 11.1 and olderTo work around this problem, reduce the length of your target directory or the length of the names of your submodules. This might require that you set your target directory to the root of a mounted drive in Windows to ensure that the path length does not become too long.
For example, your target directory might have been:
C:\longusername\my_projects\very_long_project_description_name\revision_number_x\netlist_test_for_some_hardware_in_the_loop_target
You could change your target directory to:
C:\netlist
