ABSTRACT:
An interactive diagnostic methodology and apparatus that enables a specimen (microelectronic device) to undergo detailed behavioral examination while allowing the Diagnostician to incrementally proceed from a set of symptoms to a formal diagnosis. Diagnostic tactics are predicated on comparing measured behavior to predicted behavior. The methodology allows coupling to a variety of behavior-level, switch-level (state), and circuit-level (node) simulators in determining predicted behavior. The architecture allows a variety of beam-probing apparatus to be supported in acquiring nodal waveforms and logic state images from a specimen as a means of determining measured behavior. This measured behavior can be graphically compared to the predicted behavior for study and analysis by the Diagnostician to aid in the formulation of diagnostic tactics. The ability to easily couple a wide variety of simulation techniques and beam probing apparatus is achieved by viewing simulation and measurement as generic functions, which can be executed concurrently, from an architectural standpoint. To accelerate nodal navigation and model extraction, an object clustering data structure is used that exploits apriori continuity relationships between objects, symbolically representing the specimen's design. The importance of defining stimuli, for exercising the specimen under various measurement and simulation conditions, is fully recognized with an integrated capability for the interactive composition and modification of stimuli patterns. The apparatus architecture provides for network coupling to the CAD environment for access to information concerning the specimen's design and in performing simulation activities to support diagnostic tactics.
