Check uniqueness of State names

Check ID: mathworks.jmaab.jc_0730

Guideline: jc_0730: Unique state name in Stateflow^® blocks

Description

Stateflow state names must be unique in charts, with the exception of atomic subcharts. Atomic subcharts are treated as different container so they can share State names with other states outside of the subchart.

Stateflow states include the following.

Atomic Subchart
State
Simulink State

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

Condition	Recommended Action
In a Stateflow chart, two or more Stateflow states have the same name.	Rename the Stateflow states so that there are no identical names in the Stateflow chart.

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.
