Silicon Integration Initiative, an electronic design automation software research and development joint venture, has released Data Model 6, the newest version of OpenAccess, the world’s most widely used standard API and reference database for integrated circuit design.
DM6 is the first major OpenAccess revision since 2014. The OpenAccess database provides EDA software tools with immediate design flow interoperability, saving time and money for semiconductor designers and manufacturers. Innovative DM6 features will improve performance in both new and legacy applications.
Marshall Tiner, Si2 director of Production Standards, said DM6 can help the industry keep pace with design requirements for emerging artificial intelligence and machine learning applications. “As with all OpenAccess releases, DM6 is a production-quality, proven, stable design platform. It’s uniquely positioned to meet the new complexity and performance challenges facing IC designers.”
A key feature of DM6 is oaPartitions, which enables OpenAccess applications to access critical components of enormous designs as easily as opening much smaller designs, saving compute resources and allowing developers to start doing meaningful work faster. “The real power of DM6 comes from the new partitioning capability. By subdividing a complex design, OpenAccess provides simultaneous access to multiple partitions from separate processes. Applications can use oaPartitions to exploit the full compute power available on the user’s platform,” Tiner said.
With properly written applications taking advantage of the new data model, oaPartitions can customize how and what data will be loaded into memory from the database. Multiple simultaneous, unique applications can each be assigned their own partition, opening up a wide range of opportunities to accelerate the design flow on ever-growing, complex designs.
“The industry is looking for enablers for utilizing vast cloud-based hardware with multiple processors. oaPartitions provides just that,” Tiner said.
John Ellis, Si2 president and CEO, underscored the benefits of OpenAccess. “Use of OpenAccess API, source code, and scripting capability accelerates EDA vendor’s time to market, and provides users with tool-to-tool interoperability for optimal design flows. Without OA compatibility, time-consuming translations in and out of a vendor or user internally developed software tools are usually required, wasting some of the productivity gains a tool provides. Any software tool used for real-world, physical design that is not utilizing OA is at a serious disadvantage. The high-performance, partitioning capability of OA DM6 underscores the competitive advantage and power of OpenAccess.”
The OpenAccess Coalition is the governing body that manages the OpenAccess infrastructure. Cadence Design Systems, Inc. contributed the OpenAccess API to Si2 in 2002 and serves as the co-architect of the Si2 Change Team that manages modifications to the API and data model. Cadence also provides Si2 and its OpenAccess Coalition members with rights to use their production-quality, reference implementation of the latest API and data model. DM6 is now available to all coalition members.
