Although a significant fraction of emerging failure and wearout mechanisms result in intermittent or permanent faults in hardware, their impact (as distinct from transient faults) on software applications has not been well studied. In this paper, the authors develop a distinguishing application characteristic, referred to as similarity from fundamental circuit-level understanding of the failure mechanisms. They present a mathematical definition and a procedure for similarity computation for practical software applications and experimentally verify the relationship between similarity and fault rate.
