Rule

Sub ID a

Variables that are used in a state transition condition shall not use state action du to perform an update.

Custom Parameter

Not Applicable

Example — Correct

Example — Incorrect

State action du is used to perform an update.

Rationale

Sub ID a:

• The execution order of the transition condition and implement of during can be difficult to understand, which increases the risk of errors.

Verification

Model Advisor check: Check updates to variables used in state transition conditions (Simulink Check)
