SystemRDL
The SystemRDL language, supported by the SPIRIT Consortium, was specifically designed to describe and implement a wide variety of control status registers. Using SystemRDL, developers can automatically generate and synchronize register views for specification, hardware design, software development, verification, and documentation. SystemRDL is an open source text based descriptive language that focuses exclusively on registers. SystemRDL 1.0 had some limitations and is now superseded by SystemRDL 2.0 which has support for verification based properties like constraints, coverage, and HDL paths. SystemRDL 2.0 also introduces the ability to parameterize components which further improves design re-use.

SPIRIT Consortium
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. 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. The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance and then developed IP-XACT. The merger was com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. History SystemVerilog started with the donation of the Superlog language to Accellera in 2002 by the startup company Co-Design Automation. The bulk of the verification functionality is based on the OpenVera language donated by Synopsys. In 2005, SystemVerilog was adopted as IEEE Standard 1800-2005. In 2009, the standard was merged with the base Verilog (IEEE 1364-2005) standard, creating IEEE Standard 1800-2009. The current version is IEEE standard 1800-2017. The feature-set of SystemVerilog can be divided into two distinct roles: # SystemVerilog for register-transfer level (RTL) design is a ...

IP-XACT
IP-XACT is an XML format that defines and describes individual, re-usable electronic circuit designs (individual pieces of intellectual property, or IPs) to facilitate their use in creating integrated circuits (i.e. ''microchips''). IP-XACT was created by the SPIRIT Consortium as a standard to enable automated configuration and integration through tools. The goals of the standard are * to ensure delivery of compatible component descriptions from multiple component vendors, * to enable exchanging complex component libraries between electronic design automation (EDA) tools for SoC design (design environments), * to describe configurable components using metadata, and * to enable the provision of EDA vendor-neutral scripts for component creation and configuration (generators, configurators). Approved as IEEE 1685-2009 on December 9, 2009, published on February 18, 2010. Superseded by IEEE 1685-2014. IEEE 1685-2009 was adopted as IEC 62014-4:2015. Overview All documents will have ...

Control Status Register
Control and Status Register (CSR) is a register in many central processing units that are used as storage devices for information about instructions received from machines. The device is generally placed in the register address 0 or 1 in CPUs and works on the concept of using a comparison of flags A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employ ... (carry, overflow and zero, usually) to decide on various if-then instructions related to electronic decision flows. In digital devices, the control and status registers are described by a register map.BT Register Maps & Control Status Registers/ref> References {{DEFAULTSORT:Control Status Register Digital registers ...

Juniper Networks
Juniper Networks, Inc. is an American multinational corporation headquartered in Sunnyvale, California. The company develops and markets networking products, including routers, switches, network management software, network security products, and software-defined networking technology. The company was founded in 1996 by Pradeep Sindhu, with Scott Kriens as the first CEO, who remained until September 2008. Kriens has been credited with much of Juniper's early market success. It received several rounds of funding from venture capitalists and telecommunications companies before going public in 1999. Juniper grew to $673 million in annual revenues by 2000. By 2001 it had a 37% share of the core routers market, challenging Cisco's once-dominant market-share. It grew to $4 billion in revenues by 2004 and $4.63 billion in 2014. Juniper appointed Kevin Johnson as CEO in 2008, Shaygan Kheradpir in 2013 and Rami Rahim in 2014. Juniper Networks originally focused on core routers, whic ...

GitHub
GitHub, Inc. () is an Internet hosting service for software development and version control using Git. It provides the distributed version control of Git plus access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project. Headquartered in California, it has been a subsidiary of Microsoft since 2018. It is commonly used to host open source software development projects. As of June 2022, GitHub reported having over 83 million developers and more than 200 million repositories, including at least 28 million public repositories. It is the largest source code host . History GitHub.com Development of the GitHub.com platform began on October 19, 2007. The site was launched in April 2008 by Tom Preston-Werner, Chris Wanstrath, P. J. Hyett and Scott Chacon after it had been made available for a few months prior as a beta release. GitHub has an annual keynote called GitHub Universe. Organizational ...
