Coalition offers OpenAccess source code

Marking a major milestone for EDA tool interoperability, the OpenAccess Coalition has announced the availability of source code for the OpenAccess 2.0 database. The database's availability is viewed as an essential step towards the coalition's goal of an industry-wide application programming interface (API) and data model for IC design tools.

While an API and binary implementation of OpenAccess have been available for some time, many EDA vendors have been waiting for the source code of version 2.0 - considered the "production ready" release - before agreeing to support the initiative. Cadence Design Systems Inc. developed the OpenAccess database, originally called Genesis, and is starting to deploy it in its IC physical design products.

Cadence announced the release of OpenAccess 2.0 source code to the OpenAccess Coalition on Dec. 16. The Silicon Integration Initiative (Si2), which hosts the OpenAccess Coalition, pledged at that time to make the code available to the engineering community in early January.

The OpenAccess API, binary implementation and source code are all available free of charge at Si2's Open EDA Web site. While the database involves no royalty or licensing fees, source code access requires a written license with Si2.

OpenAccess 2.0 is said to have the necessary infrastructure to meet requirements for IC physical design, including new levels of capacity and performance, analog/mixed-signal content, 64-bit thread safe C++ architecture, and extensibility. In addition to the API specification and database, OpenAccess 2.0 includes developer documentation, conversion utilities from LEF and DEF, sample applications, and a Python language binding.

Eyes on Synopsys

With the source code released, the EDA industry's focus shifts to Synopsys Inc., which has promised to outline plans for opening its Milkyway database in January. Milkyway and other databases could conceivably be implemented under the OpenAccess API.
