Top-Level Goals · Functional Requirements · Technical Allocation
Overview
Safety goals are decomposed into functional safety requirements and then into technical safety requirements, allocated to system elements and verified through model-based safety analysis — ensuring full traceability from hazard to design implementation. Our requirements modelling approach integrates Ansys medini analyze with requirements management tools to maintain a live, auditable safety case that is updated as the design evolves through concept, system, and software development phases.

Key Aspects
Translating safety goals into functional safety requirements at the system level — defining what the system must do (and not do) to maintain safe state.
Decomposing functional safety requirements into technical requirements allocated to hardware and software elements, with defined safety mechanisms for each.
Splitting ASIL requirements between two independent channels to reduce the individual ASIL target for each — enabling more cost-effective hardware implementation.
Maintaining a complete, auditable trace from every safety goal through functional and technical requirements to design elements and verification results.
