Abstract

Slightly-off-specification (SOS) failures can occur at the interface between the analog and the digital world. If an erroneous node in a distributed system produces an output signal (in time or value) slightly outside the specified window, some nodes will correctly receive this signal, while others might fail to receive it. Such a scenario will result in an inconsistent state of the distributed system. We present the observed temporal SOS failures in the time-triggered architecture with the bus interconnection structure during the execution of the software implemented fault injection in the TTP/C communication controller. Solutions to avoid the occurrence of the temporal SOS failures in the time-triggered architecture are analyzed and presented.
