Check usage of logical operators and functions in MATLAB Function blocks

mathworks.hism.himl_0010

Dependencies: Simulink® Check™

Usage: High-Integrity System Modeling

Guideline: himl_0010: MATLAB code with logical operators and functions

Description

Use this check to identify logical operators and logical functions operating on operands with numeric data types in MATLAB Function blocks.

Check Parameters

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

ParameterDescription
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 ConditionRecommended Action
Logical operators or logical functions operates on operands with numeric data types.Type cast the operands to be of a logical data type.

Capabilities and Limitations

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

  • Does not run on library models

  • Allows exclusions of blocks and charts

  • Analyzes only active variant choices

  • Performs model compilation
