Check usage of log and log10 operations
mathworks.sldv.hism.hisl_0004
Dependencies: Simulink® Check™, Simulink Design Verifier™, and Stateflow®
Usage: High-Integrity System Modeling
Guideline: hisl_0004: Usage of natural logarithm and base 10 logarithm operations
Description
This check identifies natural logarithm (log
) and base 10
logarithm (log10
) operations in the model that can cause nonfinite
results. This check performs SLDV analysis on the model. Running this check triggers an
extensive analysis using Simulink
Design Verifier.
Check Parameters
Use the Model Advisor Configuration Editor to define the scope of the analysis by specifying the input parameters.
Parameter | Description |
---|---|
Follow links | Specify whether to include content of library-linked blocks in the analysis.
|
Look under masks | Specify whether to include masked model elements in the analysis.
|
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 |
---|---|
Natural or base 10 logarithm (Log and
Log10 ) operations in the model have inputs
that can be less than or equal to zero during simulation. | Make sure that the input of log and
log 10 operations in the model are not less
than or equal to zero. |
Capabilities and Limitations
Does not run on library models
Allows exclusions of blocks and charts
Analyzes only active variant choices
Performs extensive analysis
