Bokkapitel (refereegranskat)abstract
- EAST-ADL is an Architecture Description Language (ADL) initially defined in several European-funded research projects and subsequently refined and aligned with the more recent AUTOSAR automotive standard. It provides a comprehensive approach for defining automotive electronic systems through an information model that captures engineering information in a standardized form. Aspects covered include vehicle features, requirements, analysis functions, software and hardware components, and communication. The representation of the system’s implementation is not defined in EAST-ADL itself but by AUTOSAR. However, traceability is supported from EAST-ADL’s lower abstraction levels to the implementation level elements in AUTOSAR. In this chapter, the authors describe EAST-ADL in detail, show how it relates to AUTOSAR as well as other significant automotive standards, and present current research work on using EAST-ADL in the context of fully-electric vehicles, the functional safety standard ISO 26262, and for multi-objective optimization.

- EAST-ADL is an architecture description language (ADL) for model-based development of automotive embedded systems.The formalization of domain-specific engineering information and methodology brings a potential for a wide range of benefitsfor information management, system design and integration, tool interaction, documentation and communication. This paper describesthe EAST-ADL language support for safety requirements, faults/failures, hazards and safety constraints in the context of ISO/DIS 26262reference safety lifecycle. Based on the language support, the safety related information can be derived and managed seamlessly alongwith its target nominal system architecture model with multiple abstraction levels and view extensions. Through model transformationand tool integration, automated safety analysis is allowed.

Konferensbidrag (refereegranskat)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.
