Check usage of log and log10 operations

Check ID: mathworks.sldv.hism.hisl_0004


Identifies log and log10 operations in the model that can cause nonfinite results.

Available with Simulink® Check™. This check requires a Simulink Design Verifier™ (SLDV) license.

Note: This check will perform SLDV analysis on the model.

Results and Recommended Actions

ConditionRecommended Action
Natural/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.

  • Analyzes content of library linked blocks. By default, the input parameter Follow links is set to on.

  • Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to all.

  • Allows exclusions of blocks and charts.
