Abstract
Aspects of the invention relate to techniques for fault diagnosis based on dynamic circuit design partitioning. According to various implementations of the invention, a sub-circuit is extracted from a circuit design based on failure information of one or more integrated circuit devices. The extraction process may comprise combining fan-in cones of failing observation points included in the failure information. The extraction process may further comprise adding fan-in cones of one or more passing observation points to the combined fan-in cones of the failing observation points. Clock information of test patterns and/or layout information of the circuit design may be extracted and used in the sub-circuit extraction process. The extracted sub-circuit may then be used for diagnosing the one or more integrated circuit devices.
