Check Signed Integer Division Rounding mode

Check ID: mathworks.jmaab.jc_0642

Guideline: jc_0642: Integer rounding mode setting

Description

Identifies blocks whose parameter Integer Rounding Mode is set to Simplest when the configuration parameter Signed Integer Division Rounds is set to Undefined.

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
If the parameter Integer Rounding Mode of the listed blocks is set to Simplest when the parameter Signed Integer Division Rounds is set to Undefined.	Set the parameter Signed Integer Division Round to a value that describes the rounding behavior of your production target, or change the Integer Rounding Mode of the listed blocks to a value other than Simplest.

Capabilities and Limitations

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 blocks and charts.
