Why do I get a "License Checkout Failed. Coverage will be disabled" when I try to use the Multiple Simulations feature in Simulink?

• R2022b, Update 4

The multiple simulations feature doesn't require a Simulink Coverage toolbox by default.  This toolbox is only required if the coverage data needs to be collected for the simulation runs. For more information, please visit:

Collect Coverage for Multiple Simulations by Using Design Studies

https://www.mathworks.com/help/slcoverage/ug/collect-coverage-for-multiple-simulations.html

For R2022a:

If you aren't using Simulink Coverage but receiving this error, this is because Simulink is checking for the Simulink Coverage license even when the coverage setting is disabled. This issue has been fixed in Update 6.

To verify Simulink Coverage Toolbox is included in your license, run the following command in the MATLAB Command Window:

>> license checkout Simulink_Coverage

If you receive the following output, then the Simulink Coverage Toolbox is not included in your license:

License checkout failed.
License Manager Error -5
Cannot find a license for Simlunk_Coverage.

ans =

0

If you receive the following output, then you are licensed for the Simulink Coverage Toolbox, and you need to install the toolbox:

ans =

1

For more information on installing a toolbox onto an existing MATLAB installation, please refer to the following article:
