The less visible side of developing safety-critical systems in the automotive environment.
Proper safeguarding of safety-critical systems in an automotive environment cannot be ensured sufficiently without taking timing into consideration. The failure to observe timing constraints can lead to malfunctions and, in a worst-case scenario, can cause vehicle damage and personal injury. AUTOSAR 4.0 now supports timing constraints, but the standard, although very powerful, still is not able to address all aspects and requirements for electric/electronic (E/E) architectural design. However, alternative standards, such as EastADL2 and the Timing Extension (TIMMO) standard, have tackled this issue. This paper discusses a way to combine AUTOSAR with EastADL2 and the TIMMO timing language (TADL), enabling a consistent, top-down design approach at both the functional and timing levels.
