Check usage of Discrete-Time Integrator block

Check ID: mathworks.jmaab.jc_0627

Guideline: jc_0627: Usage of Discrete-Time Integrator blocks


Checks use of the Discrete-Time Integrator block.

For Discrete-Time Integrator blocks, check if:

  • Block parameter Limit output is selected.

  • Saturation limits is defined using a Simulink.Parameter or MPT.Parameter object whose data type is auto.

This check requires a Simulink® Check™ license.

Check Parameterization

This check contains sub-checks that correspond to sub IDs specified in the MAB and JMAAB modeling guidelines. You can use the Model Advisor Configuration Editor to specify which sub IDs (one or multiple) to execute.

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, b

Results and Recommended Actions

Capabilities and Limitations

  • Runs on library models.

  • Supports exclusions.

  • 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.
