hisl_0048: Configuration Parameters > Math and Data Types > Application lifespan (days)

R2026b

Set application lifespan to infinity for systems that run continuously

Usage: High-Integrity System Modeling

Guideline ID: hisl_0048

Rules

hisl_0048: Configuration Parameters > Math and Data Types > Application lifespan (days)

To support the robustness of systems that run continuously, set configuration parameter Application lifespan (days) to inf.

Rationale

Support robustness of systems that run continuously.

Verification

Check safety-related optimization settings for application lifespan (Simulink Check)

Tips

  • Embedded applications might run continuously. Do not assume a limited lifespan for timers and counters. When you set Application lifespan (days) to inf, the simulation time is less than the application lifespan.
