Check if/elseif/else patterns in MATLAB Function blocks

mathworks.hism.himl_0006

Dependencies: Simulink^® Check™

Usage: High-Integrity System Modeling

Guideline: himl_0006: MATLAB code if / elseif / else patterns

Description

Use this check to identify if/elseif/else patterns without appropriate else conditions in embedded MATLAB^® code.

Check Parameters

Use the Model Advisor Configuration Editor to define the scope of the analysis by specifying the input parameters.

Parameter	Description
Check external .m files referenced in the model	Specify whether to run on referenced MATLAB files in the model. on (default) | off
Follow links	Specify whether to include content of library-linked blocks in the analysis. on (default) | off
Look under masks	Specify whether to include masked model elements in the analysis. all (default) | none | graphical | functional all — Check analysis includes all masked model elements. none — Check analysis excludes masked model elements. graphical — Check analysis includes only the graphical masked model elements. functional — Check analysis includes only the functional masked model elements.

Recommended Actions and Results

Review the violations that are flagged by the check and the recommended action for fixing the issue. After applying the changes, save the model and rerun the check analysis.

Modeling Condition	Recommended Action
Inappropriate if/elseif/else patterns are present in the embedded MATLAB code.	For every if/elseif/else pattern, add an else statement that includes at least one meaningful comment.

Capabilities and Limitations

• Analyzes only the functions that are directly referenced by the Simulink model

• Analyzes both active and inactive variant choices

• Does not require model compilation
