OpenAccess satisfies the crucial need for a single database for electronics design and EDA tool development. OpenAccess is a powerful, elegantly designed database that forms a core for EDA tools that work in an open and ittegrated IC design flow. This paper describes the OpenAccess database technology and its major features and benefits. It also explains why OpenAccess is the ideal core technology for EDA applications, and how developers and CAD engineers can leverage this new industry standard database for IC design.
