UNIQUE SELLING POINTS / BUSINESS VALUE

n Car manufacturers get the flexibility to develop new architectures with Safety In the Loop approach

n First Tier suppliers demonstrate safety conformity and optimize cost n Semiconductor manufacturers develop new architectures for safe hardware

components n Tool vendors provide an integrated tool-chain n Research organizations provide their conceptual work for analysis methods n Certification authorities certificate functional safety assessment process

OBJECTIVES

n Enable effective and compliant application of ISO26262

n Ensure exchangeability of safety related data n Evaluate concepts on realistic and

measurable industrial case studies

EXPECTED RESULTS

n Architecture Description Language based on EAST-ADL and AUTOSAR n Reference technology platform and tools n Assessment model, process description and guideline to enable compliant

application of ISO 26262

PROJECT SUMMARY

The SAFE project provides solutions for integrated safety modelling and safety analysis. The results ensure compliance with the automotive functional safety standard “ISO26262”.
