Rule

Sub ID a1

A vector signal shall use a zero-based index mode.

Custom Parameter

Not Applicable

Example — Correct

A uniform zero-based index mode is used.

Example — Incorrect

A uniform index mode is not used.

Sub ID a2

A vector signal shall use a one-based index mode.

Custom Parameter

Not Applicable

Example — Correct

A uniform one-based index mode is used.

Example — Incorrect

A uniform index mode is not used (same as the incorrect example for sub ID a1).

Rationale

Sub IDs a1, a2

• Logic is easier to understand when using a uniform index mode.

Verification

Model Advisor check: Check Indexing Mode (Simulink Check)
