Compare Simulation to Baseline Data

Open the Test File and Model

1. Use the files from the previous step, or run these commands to reopen the files needed for the example.

sltest.testmanager.load("baselineTestFile.mldatx");
sltest.testmanager.view
open_system("sldemo_absbrake");

Add Signal Tolerances and Update Model

1. In the Test Manager, in the baselineTestCase test case, expand the Baseline Criteria section. Set the Absolute Tolerance of the Ww signal to 15. For more information, see Set Signal Tolerances

2. In the sldemo_absbrake model, set the Desired relative slip constant block to 0.22.

Run the Test and Review Results

1. In the Test Manager, select baselineTestCase and click Run.

2. In the Results and Artifacts pane, expand the results in the Baseline Criteria Result section. Select the Ww signal. The Comparison tab displays the simulation output data, baseline data and tolerance in the upper plot. The lower plot displays the tolerance and the difference between the simulation output and the baseline data. The Ww signal passes the test, because the signal is stays within the specifed tolerance when compared to the baseline data.

3. The overall test fails because the other signal comparisons do not satisfy the tolerance values specified in the Baseline Criteria section of the test case.

Select the slp signal in the Baseline Criteria Result section. In the Comparison tab, the upper plot shows that the simulation output and baseline data are not the same. The lower plot displays a difference greater than the zero difference required to satisfy the baseline criteria.
