Relationship Between the IEEE-SA Corporate Program and Accellera Helps Design Automation Technology Gain Reach and Recognition

Since 2000, Accellera,  a consortium of companies in the electronic design automation field, has been developing and promoting use of design and verification specifications for semiconductors, systems, and design-tool companies. Ten of those documents have been finalized and issued in collaboration with the IEEE Standards Association (IEEE-SA) as IEEE standards.

“Working with IEEE-SA brings these standards world-wide recognition and reach,” says Yatin Trivedi, Accellera’s treasurer and a long-time member of its board of directors. “IEEE-SA is recognized globally as a leading standards-development organization for a broad range of technical areas. Standards approved or ratified by IEEE are considered ‘good for you’ without question. Accellera has a good reputation, but not on the same scale as IEEE or IEEE-SA. IEEE-SA has a vast, international member base, as well as relationships with organizations such as IEC and other international and national standards bodies. These factors make IEEE standards based on Accellera documents acceptable to a broad, world-wide audience.”

“And people know and expect that IEEE’s standards development process is rigorous, open, fair, peer-reviewed, and comprehensive,” adds Trivedi. The material that organizations like Accellera submit is viewed as a strong starting contribution to an IEEE entity standards working group (WG).

Industry organizations submit specifications to IEEE with the full understanding that they’ll no longer have the control they once had over the document’s content–but the standards that result are moreuseful. IEEE entity standards WG membership is open to any interested entity that fulfills all WG membership requirements, and the final standard is likely to have changes, major or minor, from the original contribution. The variety of viewpoints and voices in the working groups helps make the standards more robust, and the resultant stability and longevity of a standard encourages rapid, widespread adoption. The IEEE brand on a standard gives companies (users and vendors) the confidence they need to invest in implementing and using it. The new products that arise from these standards often open new markets.

“The key value of Accellera working with the IEEE,” says Karen Pieper, who chairs the IEEE 1800™ SystemVerilog Working Group and Accellera’s Technical Committee, “is that IEEE-SA’s ratification of a standard is the industry-accepted milestone that indicates maturity and usability of a technology in production environments.”

“The strong partnership between Accellera and IEEE-SA helps bring useful standards forward for worldwide use,” Pieper adds. “In the case of IEEE 1800™ (also known as the SystemVerilog standard), this partnership created an innovative hardware design language and then drove widespread industry interest and adoption.” (Within two years, System Verilog support increased from 6 companies with 9 products to 137 companies with more than 350 products.) “The IEEE also provided a fast-track adoption path to the IEC, and facilitated widespread distribution through its website.”

The demand for reliable, long-lasting batteries for mobile devices is on the rise as the electronics industry continues to add more features to their laptops, cell phones and other devices in ever greater measure to meet consumer demands for mobility and ease of use. To help industry meet the call for better rechargeable batteries, the IEEE Standards Association (IEEE-SA) Corporate Standards Program has become the place to create production standards for advanced lithium-ion and lithium-ion polymer batteries. The result: Two groundbreaking standards within IEEE’s Livium™ battery standards family, one for portable computers and the other for cellular phones.

The Livium™ Standards Concept

Livium™ standards support the manufacture and use of reliable and robust rechargeable batteries. They are the first standards to encompass the entire battery operating design, from cell to pack to device, alone and in concert. Livium™ standards set uniform criteria for battery quality and performance, affecting battery system planning, design, testing and quality assurance. The standards also limit battery failure under multiple stresses, from vibration and moisture to thermal and mechanical shock. Standards for Battery Systems The Livium™ laptop battery standard, IEEE 1625™-2004, “IEEE Standard for Rechargeable Batteries for Mobile Computers,” was created by many of the world’s major battery and computer companies in just 19 months.

IEEE 1625-2004 opened the door for more powerful batteries with greater energy density that can undergo more frequent chargedischarge cycles. Such batteries allow portable computers with powerful processsors to broaden into advanced graphic and wireless applications. The first revision to IEEE 1625, approved in 2008, built on the success of IEEE 1625-2004 and was completed in 22 months. The Livium™ mobile phone standard, IEEE 1725™-2006, “IEEE Standard for Rechargeable Batteries for Cellular Telephones,” was created in just 18 months and involved the efforts of more than 50 telephone carriers and manufacturers of batteries, cells, components and handsets. This standard improves phone user experience with advanced battery performance as phones gain new features with increased adoption. IEEE 1725 was revised in 2011, completing its work in 17 months. The accelerated schedules for these standards was made possible by the commitment of the companies involved, as well as by the IEEE Professional Services they used to help keep their efforts on track. These fee-based dedicated services include strategic project and process management, meeting planning and support, and public relations support.

IEEE 1800™-2009, “SystemVerilog,” is an internationally adopted standard that enables interoperability of tools, improves productivity and reduces costs, and overcomes limitations of traditional verification processes. This expands design automation tools and methodologies to meet the increasing complexity of verification. As a result, an entirely new set of verification methodologies were born in a short period of time, exemplifying the rapid adoption of an IEEE standard by industry. System Verilog support increased from 6 companies with 9 products to 137 companies with over 350 products in 24 months. IEEE 1800 was first published in 2005, and work is under way on another update.

IEEE 1801™-2009, “IEEE Standard for Design and Verification of Low Power Integrated Circuits,” provides interoperability via a consistent format to specify power design information and portability to low power design flows and data. It also defines consistent semantics between verification and implementation, which means that what is implemented is the same as what has been verified. IEEE 1801™-2009 is receiving broad vendor and user support worldwide, resulting in a rapid growth of solutions providers (from 5 to 33 solutions providers in the 24 months the standard was under development in IEEE). A revision project for IEEE 1801 is ongoing.

With IEEE standardization, industries attain a technological methodology with worldwide influence and a longer life cycle, so they are more willing to invest in that technology for product development. IEEE standards increase user confidence in the longevity they lend to products, avoiding conversion to a different format every year, making design and verification IP reuse possible.

IEEE 1685™-2009, “Standard for IP-XACT, Standard Structure for Packaging, Integrating and Re-Using IP Within Tool-Flows,” is the first standard description of Intellectual Property blocks in highly automated design environments and provides the electronics industry with a way to make the use of IP blocks both easier and more affordable. IEEE 1685 describes an XML Schema for meta-data documenting Intellectual Property (IP) used in the development, implementation and verification of electronic systems and an Application Programming Interface (API) to provide tool access to the meta-data. This first IEEE IP-focused standard is available for download at no cost to the worlwide design community via the GET IEEE 1685™ program, sponsored by Accellera, at: standards.ieee.org/about/get/
