This paper proposes an X-fault model for fault diagnosis of physical defects with unknown behaviors by using X symbols. An efficient X-fault simulation method and an efficient X-fault diagnostic reasoning method are presented. Based on these, an X-fault diagnosis method is described to improve the failure analysis for a wide range of physical defects in complex IC circuits.
