Why does MATLAB crash when I open DSP Builder?

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

Description When I open DSP Builder from the start menu, MATLAB crashes. MATLAB opens fine as standalone software.
Resolution

To work around this problem, separately launch MATLAB and set-up paths:

  • In the dspba installation directory, edit dsp_builder.bat to remove the command "run(\'%DSPBA_ROOT%\setup_dspba.m\');" Then each time you open MATLAB from the shortcut, manually run setup_dspba.m after opening from the command line.
  • Permanently save the file path to include the DSP Builder-added paths
  • Ignore the shortcut, open MATLAB independently and run the commands the dsp_builder.bat file executes:
    setenv(\'DSPBA_ROOT\',\'C:\altera\13.1\quartus\dspba\')


setenv(\'DSP_BUILDER_ROOT\',\'C:\altera\13.1\acds\quartus\dsp_builder\')

setup_dsp_builder
