Check for avoiding algebraic loops between subsystems

Check ID: mathworks.jmaab.jc_0653

Guideline: jc_0653: Delay block layout in feedback loops


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

ConditionRecommended 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.
