To test the simulation output of a model against a defined baseline, use a baseline test
case. In this example, use the
model to compare the simulation output to a baseline captured from an earlier state of the
To open the Test Manager from the model, on the Apps tab, under Model Verification, Validation, and Test, click Simulink Test. Then, on the Tests tab, click Simulink Test Manager.
From the Test Manager toolstrip, click New to create a test file. Name and save the test file.
The test file consists of a test suite that contains one baseline test case. They appear in the Test Browser pane.
Right-click the baseline test case in the Test Browser
pane, and select Rename. Rename the test case to
Slip Baseline Test.
Under System Under Test in the test case, click the
Use current model button to load the
sldemo_absbrake model into the test case.
To record a baseline from the system under test, under Baseline Criteria, click Capture.
In the Capture Baseline dialog box, for the file format, select
Excel. Specify a location to save the baseline to
and click Capture.
The baseline criteria file and the logged signals appear in the table. Set the

In the Test Manager, select the Slip Baseline Test case in the Test Browser pane.
On the Test Manager toolstrip, click Run.
In the Results and Artifacts pane, the new test result appears at the top of the table.
Expand the results until you see the baseline criteria result. Right-click the result and select Expand All Under.

fails because other signal comparisons specified in the Baseline
Criteria section of the test case were not satisfied.
To view the
yout.Ww signal comparison between the model and
the baseline criteria, expand

click the option button next to the
The Comparison tab opens and shows the criteria
comparisons for the
yout.Ww signal and the tolerance.
You can also view signal data from the simulation. Expand
Output and select the signals you want to plot.
The Visualize tab opens and plots the simulation output.
