Run Single Simulations Interactively in Simulink

If you select the Enable coverage analysis parameter In the Configuration Parameters dialog box and then simulate your model using the Run (Coverage) button, Simulink Coverage opens the Coverage Details pane, which contains the coverage report, highlights each block or chart in your model, and indicates how each object performed in the coverage analysis. Use the Run (Coverage) button when you want to highlight the blocks in your model, or if you want to create coverage filters for unsatisfied coverage objectives. For more information, see Basic Operation of the Model Coverage Tool and View Coverage Results in Simulink Canvas.

Run Simultaneous Simulations in Simulink Using Multiple Simulations Pane

You can use the Multiple Simulations pane to collect coverage for two or more simulations. In Simulink, on the Simulation tab, under Prepare, click Multiple Simulations. In this pane, you can create design studies, add simulation scenarios, and then run all the scenarios in series. If you have Parallel Computing Toolbox™, the simulations run in parallel. For more information, see Collect Coverage for Multiple Simulations by Using Design Studies.

Run Tests Using the Test Manager in Simulink Test

If you have a Simulink Test license, you can use the Test Manager to author and run test scenarios. In your test file, under Coverage Settings, select Record coverage for system under test. Then select the coverage metrics you want to analyze. When you collect coverage this way, the Test Manager shows the coverage summary for your tests under the Aggregated Coverage Results section. If you click the model name in the coverage summary, it highlights your model with those coverage results.

Use the Test Manager when you want to perform requirements-based testing by scoping your coverage results to linked requirements, or if you want to perform back-to-back testing to analyze consistency between your model and generated code. For more information, see Analyze Model Coverage by Using the Test Manager in Simulink Test and Assess Coverage Results from Requirements-Based Tests.

Analyze Coverage Programmatically

You can analyze coverage by using the Simulink Coverage or Test Manager API. The API you use depends on what product licenses you have or what tools you are already using. For example, if you already use the Test Manager in Simulink Test, then consider using the Test Manager API for your test automation.

You can view the model highlighting by using the cvmodelview function after creating coverage results or loading coverage results with the cvload function.
