Create Tests That Use Third-Party Test Benches

These examples show how you can use MATLAB^® to develop tests that run on third-party test benches using the Simulink^® Test™ Support Package for ASAM^® XIL Standard. One example configures a third-party test bench and creates a test that controls data acquisition by setting conditions to trigger the start and stop of data logging. The other example has two test points, that each configure a different test bench, but use the same shared test body. For more information on the Simulink Test ASAM XIL workflow, see Create and Run Tests Using the ASAM XIL Standard.

The examples inherit from the sltest.TestCase class, so you can load them into the Test Manager using Open > Open MATLAB-Based Simulink Test (.m). Then, run them in the Test Manager. Alternatively, you can run the example files at the MATLAB command line, but you cannot push data to the Test Manager from the command line.

Note

To run these examples, you must install the Simulink Test Support Package for ASAM XIL Standard. For more information, see Install and Set Up the Simulink Test Support Package for ASAM XIL Standard.

Create ASAM XIL Test with Trigger that Controls Data Acquisition

The xilexample_trigger file demonstrates how to configure a third-party test bench and run a test that uses a trigger to control the start and stop of data logging, push the logged data to the Test Manager and compare the results to baseline data.

The ABCCoTestPoint function creates a Framework object, configures a test bench port and maps test variables to test bench variables. For more information, see sltest.xil.framework.Framework and sltest.xil.framework.FrameworkConfiguration.

The testBody function initializes the framework to connect to the configured test bench and creates instances of the test variables rpm, temperature, target_rpm, and input1. Then, the function sets up logging of the rpm and temperature variables to start when rpm becomes greater than 10 and to stop after 15 seconds. Then, the function uses a Stimulation object to set up an external input to the test bench, runs the simulation, pushes the logged data to the Test Manager and verifies that the logged data and data in baseline.mat are equivalent. For more information on setting up inputs and data acquisition controls, see sltest.xil.framework.Stimulation sltest.xil.framework.Acquisition.

Create ASAM XIL Test with Two Test Benches

The xilexample_polling code file shows how to configure two test benches that can use the same test body.

The SimulinkRealTimeTestPoint function follows the same steps to configure Simulink Real-Time™ as a second test bench.

The testBody function initializes the framework to connect to the configured test bench and creates instances of the test variables rpm, temperature, target_rpm, and input1. Then, the function sets up data acquisition for rpm and temperature variables without a trigger control, configures the Stimulation object to control input to the test bench, and starts the simulation. See sltest.xil.framework.Acquisition and sltest.xil.framework.Stimulation. The function starts the simulation and waits for the temperature variable to be less than 50. When the temperature variable value is less than or equal to 50, the function verifies that the rpm variable value is greater than 100, stops the simulation, and pushes the results to the Test Manager.
