Check ID: mathworks.jmaab.jc_0656

Guideline: jc_0656: Usage of Conditional Control blocks

• MAB v5.0

• JMAAB v5.1

• JMAAB v6.0

Description

Checks if the default/else case option is enabled for Switch Case and If blocks.

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 — No recommendations

• JMAAB — a

Results and Recommended Actions

Condition	Recommended Action
Improper usage of Switch Case and If blocks.	Set the default/else case option in Switch Case and If blocks to on.
