Check for consistency in model element names

R2026b

Check ID: mathworks.jmaab.jc_0602

Guideline: jc_0602: Consistency in model element names

Description

Checks if the model elements connected to a signal are following consistent naming.

The following names must be matched exactly when directly connected with signal lines:

Inport block name
Outport block name
Structural Subsystem input port label name
Structural Subsystem output port label name
From tag name
Goto tag name
Signal line signal name

Exception 1: The name of a signal line connected to one of the below subsystems can have a different name to that of the subsystem port label name:

Reusable subsystems
Subsystems linked to a library

Exception 2: If a combination of Inport blocks, Outport blocks, and other blocks have the same block name, use a suffix or prefix for the Inport and Outport blocks for consistent naming. This can be configured through Model Advisor Configuration Editor.

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

You can configure the following parameters to customize the check action:

Input Parameter	Default Value
Consistent naming format for combination of Inport and Outport blocks	Prefix(<Prefix_tag><Signal_name><Sequence>) or Suffix(<Signal_name><Sequence><Suffix_tag>)
Prefix/Suffix tag for Inport	IN_ (Default value, can be configured)
Prefix/Suffix tag for Outport	OUT_ (Default value, can be configured)

Results and Recommended Actions

Condition	Recommended Action
One or more model elements are not consistent with the connected signal name.	Rename the deviating model elements to match the signal name, or be consistent with Inport/Outport blocks.

Tip

For Bus Element Ports, the check evaluates naming consistency based on the associated bus and element names, not the block name. When naming signals connected to a Bus Element Port:

Use either the leaf element name (for example, sig2) or a signal name derived from the bus and element hierarchy (for example, InBus_sig1_sig2).
When a Bus Element Port is connected to a Subsystem, only the full bus passes through the interface. In this case, the signal name must match the bus name (for example, InBus).

Capabilities and Limitations

Runs on library models.
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to graphical.
Allows exclusions of blocks or charts.
Does not check referenced models.

Edit-Time Checking

This check is supported by edit-time checking.
