A Circuit Fast Fault Diagnosis System Developed with PODEM Algorithm

this paper deeply studies the fault models of digital circuits and proposes a combined implementation of BIST test mode, on the basis of which a new implementation of PODEM is proposed. In addition, this paper also studies the generation of test vector algorithm and a fault diagnosis system for special purpose equipment is designed and implemented based on the research in this paper, which wins the 2 prize in a province level. Keywords—PODEM, fast fault diagnosis, BIST, SCOAP, dirigibility, observability.
