Why does the SystemConsole.refreshMasters DSP Builder function fail?

Description

When using the SystemConsole.refreshMasters DSP Builder function in the Quartus® Prime Pro Edition version 26.1.1 and above, you may see the following error:

Unable to resolve the name 'com.altera.systemconsole.matlabapi.SystemConsoleLink'

This error occurs because the Java version used by MATLAB is incompatible with com.altera.systemconsole.matlabapi.SystemConsoleLink.

For DSP Builder version 26.1.1 and later, MATLAB must use Java version 11 or later for SystemConsole.refreshMasters to run successfully.

Resolution

You can change MATLAB's Java version using either the jenv MATLAB function or the matlab_jenv executable.

For information on how to use jenv and matlab_jenv, refer to the MATLAB documentation.
