Check usage of Relational Operator blocks

Check ID: mathworks.maab.jc_0131

Guideline: jc_0131: Usage of Relational Operator blocks

Check the position of Constant blocks used in Relational Operator blocks.

When the relational operator is used to compare a signal to a constant value, the constant input should be the second, lower input.

This check requires a Simulink^® Check™ license.

Available with Simulink Check.

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:

Condition	Recommended Action
Relational Operator blocks have a Constant block on the first, upper input.	Move the Constant block to the second, lower input.

Runs on library models.
Analyzes content of library linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in masked subsystems that have no workspaces and no dialogs.
Allows exclusions of blocks and charts.
