Accellera Systems Initiative 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]


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

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