Sub ID Recommendations

• NA-MAAB — No recommendations

• JMAAB — a

MATLAB Versions

All

Rule

Sub ID a

Logical constants shall not be compared to each other.

Custom Parameter

Not Applicable

Example — Correct

Logical constants are not compared to each other.

Example — Incorrect

Logical constants are compared to each other.

Rationale

Sub ID a:

• Readability improves with consistent use of boolean-valued signal==true(boolean type constant) or (boolean-valued signal) for logical signal condition expressions.

• Prevents redundancy in the model.

• Deviation from the rule can cause unexpected issues.

Verification

Model Advisor check: Check prohibited comparison operation of logical type signals (Simulink Check)
