Check for avoiding algebraic loops between subsystems

Check ID: mathworks.jmaab.jc_0653

Guideline: jc_0653: Delay block layout in feedback loops

• MAB v6.0

• JMAAB v5.1

• JMAAB v6.0

Description

Checks the placement of Delay blocks in algebraic loops between subsystems.

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 — a

• JMAAB — a

Results and Recommended Actions

Condition	Recommended Action
Delay blocks in feedback loops are placed inside subsystem.	Delay blocks in feedback loops must be placed outside of their parent subsystem.

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.

• Allows exclusions of blocks and charts.
