The Byzantine hardware fault model

A new fault model for temporary failures is presented. This model is motivated and supported by recent experimental studies on types of temporary failures which cannot be explained by existing models. This new fault is called a Byzantine fault by analogy with the well-known Byzantine Generals problem in distributed systems. An example of an important type of Byzantine fault called a short transient is analyzed. The effects of Byzantine faults on concurrent error checking circuits are discussed. Design techniques to eliminate the effects of Byzantine faults are presented.<
