Abstract
Logic diagnosis is performed on failing reports of defective integrated circuits to derive a diagnosis report for each of the failing reports which comprise information of suspects. The suspects comprise cell internal suspects and interconnect suspects. A probability distribution of root causes for causing the defective integrated circuits is determined to maximize a likelihood of observing the diagnosis reports based on a probability for each of the suspects given each of the root causes and a probability for each of the diagnosis reports given each of the suspects. The probability for each of the diagnosis reports given each of the cell internal suspects is weighted higher than the probability for each of the diagnosis reports given each of the interconnect suspects.
