The Fault Assumptions in Distributed Integrated Architectures

R. Obermaisser, P. Peti
2007 SAE Technical Paper Series   unpublished
Using a generic system model of a distributed integrated architecture, we argue in favor of a differentiation of fault containment regions for hardware and software faults.  ...  The basis for the implementation and validation of faulttolerance strategies are realistic fault assumptions, which are captured in a fault hypothesis.  ...  For safety-critical jobs, which are part of application subsystems with reliability requirements of 10 −7 failures/hour or better (i.e., SIL 3/SIL 4 according to IEC 61508 [88] ), we assume the absence  ...
