IEEE Approves SystemVerilog(R) and Verilog(R) Standards for Electronic Design

PISCATAWAY, N.J.—(BUSINESS WIRE)—Nov. 9, 2005— The IEEE today announced that it has approved SystemVerilog, IEEE Std 1800(TM)-2005, as a new standard and has approved Verilog, IEEE Std 1364(TM)-2005, as a revision to the popular Verilog hardware description language (HDL). SystemVerilog extends the Verilog language, the predominant language used for chip design, to address the growing complexity of electronic system and semiconductor designs. SystemVerilog is a unified language for hardware design, specification, and verification that was developed within the IEEE Standard Association's Corporate Program. The revision to the Verilog language standard resolves several ambiguities and corrects minor errors.

The broad IEEE SystemVerilog 1800 standard raises productivity for hardware design, specification, simulation and validation, especially for large-gate-count, IP-based, bus-intensive chips. It is based on the SystemVerilog 3.1a hardware description and verification language (HDVL) from the Accellera standards organization, which includes such features as advanced design modeling capabilities, testbench constructs, verification methods using assertion and testbench language, and a richer coupling with other languages such as C/C++. This unified standard gives the electronic design, semiconductor and system design communities a way to make design, simulation, validation and assertion-based verification work flows more efficient. It also lets designers use other languages in conjunction with Verilog, so they can leverage existing designs and intellectual property.

"IEEE 1800 enhances the Verilog HDL to keep it at the cutting edge of the industry," said Johny Srouji, chair of the SystemVerilog 1800 Working Group and Verilog 1364 Working Group. "It offers a more powerful, integrated, concise design and verification language, allowing engineers to deal with more complex design configurations, such as deeper pipelines, greater logic functionality and a higher abstract representation of the design using fewer lines of register transfer level code."

The IEEE Standards Association (IEEE-SA) has been a primary source of electronic design automation standards since the mid 1980s. The IEEE 1364 Verilog standard, for instance, has been a common language for integrated circuit development for more than a decade and has sparked strong growth in this sector. IEEE 1800 SystemVerilog standard was sponsored by the Design Automation Standards Committee within the IEEE Computer Society and by the IEEE-SA's Corporate Advisory Group.

Standards which are created within the IEEE-SA Corporate Program are developed by company-based working groups in which each member company has one vote. This industry-oriented program often allows for standards production in only one to two years, depending on participant commitment and the use of IEEE support services. The SystemVerilog 1800 working group included a large number of technical members from electronic design and user companies who dedicated their time and worked together very hard to achieve this standard. The Corporate Program was a significant factor in the rapid production of SystemVerilog 1800.

"The IEEE 1800 standard was developed in a very short period, twelve months, as a result of excellent collaboration and contributions of all working group members and underlying technical committees," said Chuck Adams, chair of the IEEE Standards Association (IEEE-SA) Corporate Advisory Group (CAG). "Accellera played a major and important role in enabling this achievement, through the donation of Accellera SystemVerilog 3.1a, in addition to continuous and outstanding cooperation with the IEEE 1800 group throughout the development of this standard."

Pricing and Availability

About the IEEE Standards Association

The IEEE-SA is a globally recognized standards-setting body which develops consensus standards through an open process that brings diverse parts of an industry together. These standards set specifications and procedures based on current scientific consensus. The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development. Over 15,000 IEEE members worldwide belong to IEEE-SA and voluntarily participate in standards activities. For information on IEEE-SA see:
