You can create signals in the SystemTest™ software and use them to test a Simulink® model. The Test Case Editor provides a graphical way of creating, editing, and visualizing signal data in SystemTest.
Use this tool to create signals based on commonly used patterns and to specify values for attributes of those signal segments. You can easily create the following types of signals:
The tool also allows you to view and manage buses and signals, and to organize them into test cases. You can manage a large number of test cases and signals.
The Test Case Editor is accessed through the Test Case Data test vector in the SystemTest software.
The following definitions apply to creating and editing signals in the Test Case Editor.
Segment — A common signal pattern providing property configurations specific to its type. This individual portion of a signal is used as a building block for constructing more complex signals.
Signal — An array of time-based data used for testing a Simulink model. Created from one or more segments.
Test Case — Created in the Test Case Editor, a collection of one or more signals that can be treated as a set of inputs to a Simulink model.
See Create Test Cases.
Test Case Data test vector — Type of test vector in the SystemTest software used to manage a 1xN array of test cases. Also the way to open the Test Case Editor from the SystemTest software.
Edit view — View in the Test Case Editor that shows plots of the selected signals in a test case. Where you build and edit signals.
See Edit View.
Test Case view — View in the Test Case Editor that shows a graphical representation of each signal. Allows an easy way to find and manage signals when you have many signals in a test case.
See Test Case View.
Test Case Options — Accessed by right-clicking a test case, options that govern the length of test cases and place to add a description.
See Test Case Options.
Signal Properties — Properties, such as extrapolation policy and data type, set on an entire signal in the Signal Properties area of the Edit view, and place to name a signal.
Segment Properties — Properties set on an individual signal segment in the Segment Properties area of the Edit view. Place to define duration and values of the segment.
