Accellera

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.{{cite news |title=EDA Standards Organizations Accellera and The SPIRIT Consortium Announce Plans to Merge |url=http://eecatalog.com/chipdesign/2009/06/12/eda-standards-organizations-accellera-and-the-spirit-consortium-announce-plans-to-merge/}} The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance{{cite news |title=SystemRDL Alliance |url=https://www.denali.com/en/partners/rdl.jsp}} and then developed IP-XACT. The merger was completed in April 2010.{{cite news |title=Standards Organizations Accellera and The SPIRIT Consortium Complete Merger |date=14 Apr 2010 |url=http://workspace.accellera.org/news/pr/view?item_key=6cc7d11a2c9c231b11d13c90fed6e33077c7a44d |access-date=9 May 2015 |archive-date=18 May 2015 |archive-url=https://web.archive.org/web/20150518080509/http://workspace.accellera.org/news/pr/view?item_key=6cc7d11a2c9c231b11d13c90fed6e33077c7a44d |url-status=dead }} 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.{{cite news |title=Accellera and Open SystemC Initiative (OSCI) Approve Merger, Unite to Form Accellera Systems Initiative |url=http://workspace.accellera.org/news/pr/view?item_key=f27cc80b296f97da1746984c3615407770f4c442}}{{cite news |title=Accellera and Open SystemC Initiative (OSCI) Approve Merger, Unite to Form Accellera Systems Initiative |url=http://www.design-reuse.com/news/27946/accellera-osci-merger.html}}

In October 2013, Accellera acquired the Open Core Protocol (OCP) standard, the intellectual property of the OCP International Partnership (OCP-IP).{{cite news |title=Accellera Systems Initiative Acquires Open Core Protocol Standard and Infrastructure to Strengthen Interoperability in Electronic Standards Development |date=15 Oct 2013 |url=http://workspace.accellera.org/news/pr/view?item_key=5e3bd6841d7dea50c6bd262f0c7c615d60b5f1a5}}

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.[http://www.spiritconsortium.org/XMLSchema/SPIRIT Schemas of The SPIRIT Consortium] 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.[http://www.eetimes.com/news/design/showArticle.jhtml?articleID=199700202 Register description format gets 'Spirit' of standardization, Richard Goering, EE Times (05/21/2007 6:00 AM EDT)] 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.[http://www.accellera.org/pressroom/2009/Accellera_SPIRIT_Merger061109_FINAL.pdf "EDA Standards Organizations Accellera and The SPIRIT Consortium Announce Plans to Merge"], press release, Accellera. June 11, 2009

There were four levels of membership in the SPIRIT consortium. The Board of Directors (BoD) was the ruling body.[http://www.spiritconsortium.org/about/roster#board_of_directors Board of Directors] Members around the time of the merge were:

• ARM Holdings
• Cadence Design Systems
• Freescale Semiconductor
• LSI Corporation
• Mentor Graphics
• NXP Semiconductors
• STMicroelectronics
• Synopsys
• Texas Instruments

Contributing members performed the standardization work and donate time and effort to the production of new specifications.[https://web.archive.org/web/20100426001830/http://www.spiritconsortium.org/about/roster#contributing Contributing Members]

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.[https://web.archive.org/web/20100426001830/http://www.spiritconsortium.org/about/roster#associate Associate Members]

Associate member status was similar to a reviewing membership but for academics and other not-for-profit organizations.[https://web.archive.org/web/20100426001830/http://www.spiritconsortium.org/about/roster#reviewing Reviewing Members]

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.

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.[http://www.accellera.org/about/members/ Members]
