Standards in Design Automation: Influencing Design and Verification Methodologies Yatin Trivedi Standards Education Committee, IEEE-SA Director of Standards, Synopsys February 11, 2011
EDA: Where Electronics Begins • Software “tools” for chip design • Architecture design • Functional design and verification • Physical design and verification • Various electrical analyses • Standards improve productivity • Tool interoperability • Data exchange, sharing, and consistency

EDA Standards Under IEEE * Test standards are under TTTC, others under DASC
Benefits to EDA Tool Developers • Don’t have to address entire design flow • Too complex for small EDA companies • Focus on core strengths • Standards help partition the problem • Integrate tools in design team’s flow • Interoperability means new business opportunities • Ability to promote own technology for widespread usage as a standard
Benefits to EDA Tool Users • Portability of design data across multiple tools • Users’ in-house special-purpose tools integrate easily with commercial tools • Reuse of design data • Among different projects • Among different design teams • Faster learning curve • Build customized design flow to suit specific requirements • Better management over tool purchases
EDA Standards Collaboration with Industry • Availability of the standard is synchronized with many marketing/promotional activities • Several product rollouts • Launching of web site • (e.g., www.systemverilog.org) • Consultants doing tutorials • Seminar series by vendors • User groups • Papers, articles, blogs, … • Wide adoption by user community • When the standard solves REAL problems, it is quickly adopted • Marketing the standard helps to accelerate its adoption rate • Wider community adoption accelerates tool maturity, use models, and entirely new methodologies • Leads to continued enhancement of the standard
EDA Standards Collaboration with Industry (cont.) • EDA standards-setting organizations bridge to IEEE • Accellera, SPIRIT, OSCI/SystemC • Incubate standards, then transfer to IEEE • EDA’s IEEE standards are sponsored by • Design Automation Standards Committee (DASC) • Test Technology Council (TTTC)
Case Study: SystemVerilog – A Success from Concept to Standard • Computer language for IC design • An industry-wide collaborative effort that started in 2001 • Co-Design, Inc. “invented” Superlog, a derivative/enhancement of Verilog HDL (IEEE 1364) • Company acquired by Synopsys in 2001 • Superlog, with many other internal technologies, proposed as extensions to Verilog for system-level modeling, design, and verification • Called “SystemVerilog”, created by Accellera • Six technology donations and many enhancements • New entity-based IEEE WG (P1800) formed after Accellera approved its SystemVerilog standard
SystemVerilog Journey • Ratified as IEEE Std. 1800-2005 • Started with SystemVerilog 3.1a from Accellera • Less than one year from transfer to ratification • More than 200 products support the standard • Rapid adoption across design and verification community • Ratified as IEEE Std. 1800-2009 • Verilog IEEE 1364 completely integrated • Large user community looking for design and verification productivity improvement • Free tutorial on IEEE Standards Education website
SystemVerilog Spawned an Entirely New Business Segment • Enabled/accelerated IP (design blocks) market segment • One language to write complex design blocks • Same language to verify design blocks • Make IP once, sell many times • Many IP providers for design and verification reuse • Networking, wireless, and consumer applications • Verification IPs as much in demand as design IPs • New methodologies invented • Assertion based verification, testbench automation • Clear inflection point in the industry to deal with large System-on-Chips
Case Study: IEEE 1801/UPF A Low-Power IC Standard • Ever-growing need for low-power ICs in mobile/portable devices and data centers • Industry recognized need for low-power IC standard • Common way for design and verification engineers to describe IC’s low-power properties • EDA users and vendors came together to develop a format and methodology • Effort started in 2006 under Accellera • Merged 6 technology donations for multi-faceted requirements • Unified Power Format (UPF) created in 6 months • Ratified as IEEE Std. 1801-2009 • Less than 18 months under entity process
Case Study: IEEE 1685 IP-XACT • Meta-data about semiconductor IP • Composing systems using/reusing IP – consistent, complete • Originally developed under The SPIRIT Consortium • Ratified as SPIRIT standard in 2007 (version 1.0, 1.5) • XML Schemas published • IP-XACT 1.5 donated to IEEE P1685 • Ratified as IEEE Std. 1685-2010
Why Standards Education Is Important • Standards education recognizes the key role standards play within the engineering, technology and computing fields. • Knowledge of standards can help facilitate the transition from classroom to professional practice by aligning educational concepts with real-world applications. • Incorporating standards into the curriculum … • Benefits students and faculty mentors as they face challenging design processes • Provides tools for use in learning about standards and their impact on design and development

Mission of the Standards Education Committee • Promote the importance of standards in meeting technical, economic, environmental, and societal challenges. • Secure and disseminate learning materials on the application of standards in the design and development aspects of educational programs. • Secure and provide short courses about standards needed in the design and development phases of professional practice. • Actively promote the integration of standards into academic programs. • Lead other education initiatives planned jointly by the IEEE Educational Activities Board and the Standards Association.
Conclusion • EDA users and vendors have embraced IEEE standards for three decades • Large user community active in development of standards along with vendors • Standards help broaden infrastructure for the entire industry and academia
