Guideline Publication

Control Algorithm Modeling Guidelines - Using MATLAB^®, Simulink^®, and Stateflow^®

Version 6.0

Sub ID Recommendations

NA-MAAB — a, b
JMAAB — Not supported

MATLAB Versions

All

Rule

Sub ID a

A label shall be displayed on the signal line originating from these blocks:

Inport
From (see exception)
Subsystem or Stateflow Chart (Stateflow) (see exception)
Bus Selector (the tool forces this to happen)
Demux
Selector
Data Store Read (see exception)
Constant (see exception)

Exception

When the signal label is visible in the originating block icon display, the signal does not need not to have the label displayed unless the signal label is needed elsewhere due to a destination-based rule.

Custom Parameter

Not Applicable

Sub ID b

A label shall be displayed on a signal line that connects (either directly or by way of a basic block that performs a non-transformative operation) to these destination blocks:

Custom Parameter

Not Applicable

Rationale

Sub ID a:

Improves readability, model simulation, and workflow.
Code generation may not be possible.

Sub ID b:

Improves readability, model simulation, and workflow.

Verification

Model Advisor check: Check signal line labels (Simulink Check)
