Abstract

We propose a redundancy removal method based on strongly unreachable states, which are states that have no incoming transition from any state. If a fault affects the output sequence or the state transition only when the circuit starts from strongly unreachable states, then the fault is undetectable. More over, if the unreachable states are also strongly unreachable in the faulty circuit, the line corresponding the fault is redundant. In this paper, we present the theorem that the undetectable faults obtained from a strongly unreachable state remain undetectable for the circuit after removing the redundant lines corresponding to one of the faults. We also consider the condition for removing redundant lines simultaneously. Experimental results for benchmark circuits are shown.
