Using Simulink

Creating and Running Test Cases

The Test Coverage Tool provides two MATLAB commands, cvtest and cvsim, for creating and running test cases. The cvtest command creates test cases to be run by the cvsim command (see cvsim and cvtest).

You can also run the coverage tool interactively. To do so, select Coverage Settings from the Simulink Tools menu. Simulink displays the Coverage Settings dialog box (see Coverage Settings Dialog Box). Check Enable Coverage Reporting and select OK to dismiss the dialog. Then select Start from the Simulation menu or the start button on the Simulink toolbar.

By default, Simulink saves the data as a workspace object named covdata and displays the data as an HTML report at the end of the simulation run. You can select other options for generating, saving, and reporting coverage data. See the Coverage Settings Dialog Box for more information.

Note    You cannot run simulations with both model coverage reporting and acceleration options enabled. Simulink disables coverage reporting if the accelerator is enabled. If a model includes links to Stateflow library charts and you want the Model Coverage Tool to include the charts in its coverage report, you must open the library charts before starting the simulation. If a referenced library chart is not open, the tool omits the chart from its report.
