State of the Art Software Test Libraries (STL) and ASIL B: Truths, Myths, and Guidance
In recent years, the number of automotive and industrial applications with functional safety requirements has grown significantly. Internationally agreed standards are in place to ensure systems achieve the required levels of reliability and safety integrity.
Software Test Libraries (STL) are software-based safety mechanisms which provide diagnostic capabilities for permanent faults. Based on the level of diagnostic coverage that can be achieved, they are ideal for lower safety integrity requirements, such as ISO 26262 ASIL B automotive applications and IEC 61508 SIL 2 industrial systems. In addition, they are typically less complex to deploy than Built in Self Tests (BIST) and use less silicon area and power.
