Check for parentheses in Fcn block expressions

Check ID: mathworks.jmaab.jc_0622

Guideline: jc_0622: Usage of Fcn blocks

• MAB v6.0

• JMAAB v5.1

• JMAAB v6.0

Description

Checks the use of parentheses in Fcn block expressions. Parentheses must be used to define the operator precedence.

This check requires a Simulink^® Check™ 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 — No recommendations

• JMAAB — a

Results and Recommended Actions

Condition	Recommended Action
Improper usage of Fcn block expressions.	Resolve the operator precedence in Fcn block expressions by adding parentheses.

Capabilities and Limitations

• Runs on library models.

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

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

• Does not allow exclusions of blocks and charts.
