Abstract
A method and system for subnet defect diagnostics through fault compositing is disclosed. A testing apparatus generates callout data for an integrated circuit device under test. A computer received the callout data, which includes a list of faults. Each fault of the list of faults has associated with it one or more failures and/or conflicts. In order to explain the failures, two or more faults are selected and composited, yielding a composite fault having a composite conflict count. The composite fault is assigned a score based on the composite conflict count, which score determines a candidate composite that best explains the faults of the list of faults. This procedure may be repeated to explain all the failures.
