Accellera
Summary
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.
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. The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance and then developed IP-XACT. The merger was completed in April 2010. 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.
In October 2013, Accellera acquired the Open Core Protocol (OCP) standard, the intellectual property of the OCP International Partnership (OCP-IP).
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. 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. 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.
There were four levels of membership in the SPIRIT consortium. The Board of Directors (BoD) was the ruling body.

SystemC
SystemC is a set of C++ classes and macros which provide an event-driven simulation interface (see also discrete event simulation). These facilities enable a designer to simulate concurrent processes, each described using plain C++ syntax. SystemC processes can communicate in a simulated real-time environment, using signals of all the datatypes offered by C++, some additional ones offered by the SystemC library, as well as user defined.
SystemVerilog
SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems. SystemVerilog is based on Verilog and some extensions, and since 2008, Verilog is now part of the same IEEE standard. It is commonly used in the semiconductor and electronic design industry as an evolution of Verilog. SystemVerilog started with the donation of the Superlog language to Accellera in 2002 by the startup company Co-Design Automation.
Hardware description language
In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, and most commonly, digital logic circuits. A hardware description language enables a precise, formal description of an electronic circuit that allows for the automated analysis and simulation of an electronic circuit.
