Accellera

Accellera Systems Initiative (Accellera) is a standards organization that supports a mix of user and vendor standards and open interfaces development in the area of electronic design automation (EDA) and integrated circuit (IC) design and manufacturing. It is less constrained than the Institute of Electrical and Electronics Engineers (IEEE) and is therefore the starting place for many standards. Once mature and adopted by the broader community, the standards are usually transferred to the IEEE.[1]

History

In 2000, Accellera was founded from the merger of Open Verilog International (OVI) and VHDL International, the developers of Verilog and VHDL respectively. Both were originally formed nine years earlier in 1991.

In June 2009, a merger was announced between Accellera and The SPIRIT Consortium, another major EDA standards organization focused on IP deployment and reuse.[2] The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance[3] and then developed IP-XACT. The merger was completed in April 2010.[4] SPIRIT stood for "Structure for Packaging, Integrating and Re-using IP within Tool-flows".

In December 2011, Accellera and the Open SystemC Initiative (OSCI) approved their merger, adopting the name Accellera Systems Initiative (Accellera) while continuing to develop SystemC.[5][6]

In October 2013, Accellera acquired the Open Core Protocol (OCP) standard, the intellectual property of the OCP International Partnership (OCP-IP).[7]

The SPIRIT Consortium

The SPIRIT Consortium was a group of vendors and users of electronic design automation (EDA) tools, defining standards for the exchange of System-on-a-chip (SoC) design information.[8] The standards defined included IP-XACT, an XML schema for vendor-neutral descriptions of design components, and SystemRDL, a language for describing registers in components.[9] SPIRIT stood for "Structure for Packaging, Integrating and Re-using IP within Tool-flows".

In June 2009 it was announced that SPIRIT would merge with Accellera.[10]

SPIRIT membership

There were four levels of membership in the SPIRIT consortium. The Board of Directors (BoD) was the ruling body.[11] Members around the time of the merge were:

Contributing members performed the standardization work and donate time and effort to the production of new specifications.[12]

Reviewing member status was a free membership for companies. These get early access to specifications to facilitate a deep review round of each proposal before it goes public.[13]

Associate member status was similar to a reviewing membership but for academics and other not-for-profit organizations.[14]

Open Core Protocol International Partnership Association

The Open Core Protocol International Partnership Association, Inc. (OCP-IP) was an independent, non-profit semiconductor industry consortium formed to administer the support, promotion and enhancement of the Open Core Protocol (OCP). OCP was the first fully supported, openly licensed, comprehensive, interface socket for semiconductor intellectual property (IP) cores. The mission of OCP-IP was to address problems relating to design, verification, and testing which are common to IP core reuse in "plug and play" system on a chip (SoC) products. This initiative comprehensively fulfills system-level integration requirements by promoting IP core reusability and reducing design time, risk and manufacturing costs for SoC designs. Design teams developing consumer, data processing, telecom (wireless or wired), datacom and mass storage applications can gain significant benefits from the OCP-IP solution.

Accellera membership

Corporate members have a right to be eligible for election to the Board of Directors. Associate member companies have voting rights in all of Accellera's Technical Working Groups.[15]

Standards

The following EDA standards developed by Accellera were ratified by IEEE by 2019:[2]

The following EDA initiatives were developed by Accellera:

gollark: Other sentences you could include:- "I will be there; I cannot be stopped; my presence is utterly inevitable."- "I await our meeting with interest."- "It is already too late."
gollark: "Dear apioform,Yes, this time works for me.Yours sincerely, wico979"
gollark: ↓ gollark
gollark: ↓ palaiologos
gollark: It's perfectly consistent. You're just bad.
