Check scope of data in parallel states

Check ID: mathworks.jmaab.jc_0722

Guideline: jc_0722: Local data definition in parallel states


The scope of local variables must be set as restricted to one parallel state unless that same data is required by two or more parallel states.

This check requires a Simulink® Check™ and Stateflow® license.

Check Parameterization

This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.

For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:

  • NA-MAAB — a

  • JMAAB — a

Results and Recommended Actions

ConditionRecommended Action
The scope of Stateflow data (local variables) is not restricted to a parallel state when the same data is not required by multiple parallel states.Restrict the scope of Stateflow data (local variables) to only one parallel state.

Capabilities and Limitations

  • Runs 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 graphical.

  • Allows exclusions of charts.
