As described in Author and Use Signals in Tests, you create a Test Case Data test vector from the SystemTest™ software, and then add signals to it using the Test Case Editor. This example starts from the Test Vectors pane.
To create the Test Case Data test vector:
On the Test Vectors pane of SystemTest software, click the New button.
In the Insert New Test Vector dialog box, select Test Case Data as the test vector type.
Assign a name to the vector in the Name field.
Click OK in the Insert Test Vector dialog box.
The new vector appears in the Test Vectors pane.
On the Test Vectors pane, select the test vector you just created, and click the Open Test Case Editor button to create the test cases and signals, as described in Author and Use Signals in Tests.
Alternatively, you can click the Open Test Case Editor button after step 3, while creating the test vector. If you do that, click OK in the Insert Test Vector dialog box once you return to the SystemTest desktop.
Whether you create the test cases and signals during creation of the test vector, or after you have created it, see Create Test Cases, Signals, and Buses for information on creating and editing the test cases and signals.
Note: For an example of using signals created in the Test Case Editor in a Simulink element, see Test Cases and Signals in Simulink Element.
Note: You can access the signal data from a Test Case Data test vector by using a MATLAB element in your test. For an example of this, see Access Test Case Data Using MATLAB Element.
