Simulink® provides diagnostic messages when certain conditions are detected during a Simulink operation on a model. The diagnostic messages are captured under error, information, or warning categories.
The diagnostic messages you encounter in programmatic operations are displayed in the
MATLAB® Command Window, while those you encounter during a Simulink user interface operation are displayed in the Diagnostic
Viewer. For example, if you simulate a model from the MATLAB command prompt using the
the diagnostics messages are displayed in the Command Window. However, if
you run a simulation from the Simulink Toolstrip, the diagnostic messages are displayed in the
You can customize the diagnostic messages, and also customize the conditions the software checks to either produce errors or warnings.
The diagnostics for model are displayed in the Diagnostic Viewer user interface. To know more about the diagnostic viewer, see the topic View Diagnostics.
You can also add Model Verification blocks to your model, to check the condition of specific signals. For more information about Model Verification, see topics listed under Run Model Advisor Checks.
