Abstract :
In this paper we present generic CPU self-test programs and we check if the test programs conform to the IEC 61508 safety standard. We use processor architecture independent test programs to indirectly test the CPU components. We present a fault injection framework which we use to verify the fault detection ratio of the self-tests through simulation on a Plasma/MIPS and on a LEON3 processor.
