Abstract

In this paper, we describe a concept for the automatic allocationof general Safety Integrity Levels (SILs) to subsystems andcomponents of complex hierarchical networked architectures thatdeliver sets of safety critical functions. The concept is generic andcan be adapted to facilitate the safety engineering approachdefined in several standards that employ the concept of integrityor assurance levels including ISO 26262, the emergingautomotive safety standard. SIL allocation is facilitated by HiPHOPS,an automated safety analysis tool, and can be performed inthe context of development using EAST-ADL2, an automotivearchitecture description language. The process rationalizescomplex risk allocation and leads to optimal/economic allocationof SILs.
