AEI Safety Software Framework
AEI Safety Software Framework
AEI Safety Software Framework (AESF) provides assistance in the development, providing standard, low-level functionality which increases software reliability, speeds up programming time, and simplifies testing.
AESF gives foundation for safety applications compliant with ISO 26262 functional safety standard. AESF provides complete software safety mechanisms coverage for Aurix Tricore microcontroller hardware safety mechanisms. AESF is developed as Safety Element out of Context (SEooC) and allows the integration up to ASIL D and it can be used within both AUTOSAR and non-AUTOSAR applications.
