| Using Simulink | |
If errors occur during a simulation, Simulink halts the simulation, opens the subsystems that caused the error (if necessary), and displays the errors in the Simulation Diagnostics Viewer. The following section explains how to use the viewer to determine the cause of the errors.
Simulation Diagnostic Viewer
The viewer comprises an Error Summary pane and an Error Message pane.
Error Summary Pane
The upper pane lists the errors that caused Simulink to terminate the simulation. The pane displays the following information for each error.
Message. Message type (for example, block error, warning, log)
Reported by. Component that reported the error (for example, Simulink, Stateflow, Real-Time Workshop, etc.)
Source. Name of the model element (for example, a block) that caused the error
Summary. Error message, abbreviated to fit in the column
You can remove any of these columns of information to make more room for the others. To remove a column, select the viewer's View menu and uncheck the corresponding item.
Error Message Pane
The lower pane initially contains the contents of the first error message listed in the top pane. You can display the contents of other messages by clicking their entries in the upper pane.
In addition to displaying the Diagnostic Viewer, Simulink also opens (if necessary) the subsystem that contains the first error source and highlights the source.
You can display the sources of other errors by clicking anywhere in the error message in the upper pane, by clicking the name of the error source in the error message (highlighted in blue), or by selecting the Open button on the viewer.
Changing Font Size
To change the size of the font used to display errors, select Font Size from the viewer's menu bar. A menu of font sizes appears. Select the desired font size from the menu.
