| OpenAccess is a complete, next-generation database for representing IC designs with vast functionality. It features a comprehensive data model that captures both the intent and implementation of an IC design. Its high-performance access and minimal memory use makes OpenAccess the ideal foundation for an application's in-memory model. In addition, its efficient, object-oriented API makes it easy to use—without detailed knowledge of the database's internal implementation. OpenAccess is a project under the auspices of the Silicon Integration Initiative (Si2), an international organization of leading companies in the semiconductor industry. |

This is a demonstration of OpenAccess interoperability through a complete custom IC design flow. Five OpenAccess Coalition members demonstrate that an interoperable PCell library supports six tools including schematic capture, layout editing and design rule checkers. Multiple tools edit a single OpenAccess database, changing PyCell parameters and using stretch handles and automatic abutment, and the design is checked in two different DRC tools. Throughout all these operations, connectivity is maintained, and the database is never translated or streamed out. Participating OpenAccess Coalition members include Ciranova, Mentor Graphics, Silicon Canvas, Silicon Navigator and Synopsys.
