Inquiry about using the source of the sltest.harness.create function depending on the MATLAB version

Hello.

I have a question while using MATLAB.

When I used the 2021b version last year, there was a Signal Builder in the Source of the 'sltest.harness.create' function, so I used it to create a test harness.

This year, when I upgraded to the 2022b version, it seems that the Signal Builder in the Source of the 'sltest.harness.create' function has disappeared.

I would like to ask if it has been replaced with another function, or if there is another way (function) to create a harness using the Source creation form as a Signal Builder.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------

ex) sltest.harness.create(harnessUnit,'Name', harName, 'Source', 'Signal Builder')

[error]

Expected input to match one of these values: 'Inport', 'Signal Editor', 'From Workspace', 'From File', 'Test Sequence', 'Chart', 'Constant', 'Ground', 'None', 'Custom' The input, Builder', did not match any of the valid values.

Hi @WJKIM,

Apologies for the confusion. The Signal Builder was deprecated as a harness source (for new harnesses) in R2022b. Harnesses created in releases prior to R2022b which contain Signal Builder as a source are still supported. On behalf of the team, I apologize for the lack of a release note on this.

We generally recommend (across all products) the use of Signal Editor as a replacement for Signal Builder: https://www.mathworks.com/help/simulink/ug/migrate-from-signal-builder-block-to-signal-editor-block.html

There is also a function available: https://www.mathworks.com/help/simulink/slref/signalbuildertosignaleditor.html

Thanks
