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 benefits for information management, system design and integration, tool interaction, documentation and communication. This paper describes the EAST-ADL language support for safety requirements, faults/failures, hazards and safety constraints in the context of ISO/DIS 26262 reference safety lifecycle. Based on the language support, the safety related information can be derived and managed seamlessly along with its target nominal system architecture model with multiple abstraction levels and view extensions. Through model transformation and tool integration, automated safety analysis is allowed.
