This paper describes and shows some anticipated application examples for an integrated logical/physical analysis environment that utilizes the public-domain OpenAccess database as a key infrastructure element. Using an electronic design automation (EDA) database makes it possible to enrich the failure analysis and debug environment with useful EDA-type utilities and applications. The article introduces the industry-standard OpenAccess data base and illustrates how this database can be used for better integration of a more comprehensive postsilicon debug, diagnostics, and characterization environment. It provides a summary of OpenAccess and highlights the possible role for OpenAccess/Unified Data Model as a complementary technology that captures the more static information about a product's design, design analysis, and design intent information. An initial integrated logical/physical analysis environment for logic diagnostics has been established for prototyping purposes. The article also presents examples of logical/physical analysis: signal interaction analysis and probing and circuit edit.
