MISRA-SA (Safety Analysis)

 

MISRA-SA is currently working on the allocation of safety requirements. ISO 26262 introduces a process called ASIL decomposition which permits the tailoring of safety requirements allocated to independent and redundant elements of an architecture. Furthermore both IEC 61508 and ISO 26262  permit allocation of safety requirements between electrical/electronic elements as well as other technology safety-related systems and external risk reduction measures; however SIL and ASIL are only used to designate risk reduction allocated to a specific electronic item. This activity will provide new guidance on how safety requirements should be allocated between different measures and items or elements at different levels of the design process.
