Incremental fault diagnosis [PDF]
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2005 Fault diagnosis is important in improving the circuit-design process and the manufacturing yield. Diagnosis of today's complex defects is a challenging problem due to the explosion of the underlying solution space with the increasing number of fault locations and fault models. To tackle this complexity, an incremental diagnosis method is proposed. This
