Create Tests Using the Simulink Test Support Package for ASAM XIL Standard

These examples show how you can develop tests using the Simulink® Test™ Support Package for ASAM® XIL Standard. One example creates a test that configures one test bench and uses data acquisition triggering. The other test has two different test points, each of which configures a different test bench, but uses the same shared test body.

ASAM® XIL Test With Data Acquisition Triggering

This example shows a sample MATLAB® code file that uses a trigger to control data acquisition. The configuration in the ABCCoTestPoint function is for a test bench that supports data acquisition triggering.

         frm.init;
            
         rpm = frm.createVariable('rpm');
         temperature = frm.createVariable('temperature');
         target_rpm = frm.createVariable('target_rpm');
         input1 = frm.createVariable('input1');
            
         target_rpm.write(50);

         frm.Acquisition.start;
            
         % Set up a stimulation (external input) for the model.  
         % Waveform defined here lasts 5 seconds and LoopCount 
         % of 2 doubles its duration to 10 seconds. 
         tseries = timeseries(cos(2*pi*(0:1000)/200)*10,(0:1000)/200);
         frm.Stimulation.setupWithVariablesAndData(...
            {{input1,tseries}},'LoopCount',2);
         frm.Stimulation.start;
            
         frm.start;
         disp(temperature.read);
            
         frm.Acquisition.wait;
         frm.stop;
            
         result = frm.Acquisition.fetch;
         frm.pushDataToSimulinkTestManager(testCase,result);
         testCase.verifySignalsMatch(result,'baseline1.mat');
      end
   end
end

The ABCCoTestPoint function:

  • Creates a Framework object

  • Adds a model access port

  • Maps the test variables to test bench port variables

  • Calls the testBody function

The testBody function:

  • Initializes the framework

  • Instantiates the variables using the createVariable method

  • Tunes a parameter by writing a value to the target_rpm variable

  • Sets up the acquisition and triggering

  • Sets up a time series and stimulation

  • Starts the simulation and reads and displays a variable

  • Waits for acquisition to complete and stops the simulation

  • Fetches the result data, pushes it to the Test Manager, and compares it to baseline data

ASAM® XIL Test Without Data Acquisition Triggering

This example shows a sample MATLAB code file that does not use data acquisition triggering. A while loop waits for the temperature variable to be lower than or equal to 50 before finishing the test. The configuration functions specify two test benches, Simulink Real-Time™ and ABC Co. Test Bench. The test bench that is used when you run the test depends on whether you call the ABCCoTestPoint or the SimulinkRealTimeTestPoint function.

The ABCCoTestPoint and SimulinkRealTimeTestPoint functions are the same as described in ASAM® XIL Test With Data Acquisition Triggering, except the SimulinkRealTimeTestPoint function sets up three ports, which is required by Simulink Real-Time.

The testBody function:

  • Initializes the framework

  • Instantiates the variables using the createVariable method

  • Tunes a parameter by writing a value to the target_rpm variable

  • Sets up the acquisition

  • Sets up a time series and stimulation

  • Starts the stimulation

  • Starts the simulation and waits, using polling, for the temperature to be greater than 50

  • Verifies that the rpm value is greater than or equal to 100

  • Stops the simulation, fetches the result data, and pushes it to the Test Manager,
