Open Verification Methodology
The Open Verification Methodology (OVM) is a documented methodology with a supporting building-block library for the verification of semiconductor chip designs. The initial version, OVM 1.0, was released in January, 2008, and regular updates have expanded its functionality. The latest version is OVM 2.1.2, released in January, 2011. The reuse concepts within the OVM were derived mainly from the Universal Reuse Methodology (URM) which was, to a large part, based on the e Reuse Methodology (ERM) for the e Verification Language developed by Verisity Design in 2001. The OVM also brings in concepts from the Advanced Verification Methodology (AVM). The UVM class library brings much automation to the 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 20 ... language such as sequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methodology
In its most common sense, methodology is the study of research methods. However, the term can also refer to the methods themselves or to the philosophical discussion of associated background assumptions. A method is a structured procedure for bringing about a certain goal. In the context of research, this goal is usually to discover new knowledge or to verify pre-existing knowledge claims. This normally involves various steps, like choosing a sample, collecting data from this sample, and interpreting this data. The study of methods involves a detailed description and analysis of these processes. It includes evaluative aspects by comparing different methods to assess their advantages and disadvantages relative to different research goals and situations. This way, a methodology can help make the research process efficient and reliable by guiding researchers on which method to employ at each step. These descriptions and evaluations of methods often depend on philosophical background ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E Reuse Methodology
The e Reuse Methodology (eRM) was the first reuse methodology to emerge in the Hardware Verification Language space and was used in conjunction with the e Hardware Verification Language. It was invented in 2001 by Verisity Design and released in 2002. The methodology was composed of guidelines for topics such as: *File naming conventions *Functional partitioning of the testbench *Code packaging Guidelines *Sequence and message class libraries The e Reuse Methodology was widely accepted by verification engineers and is the most widely used and successful reuse methodology with thousands of successful projects. eRM formed the basis of the URM (Universal Reuse Methodology) developed by Cadence Design Systems for the SystemVerilog verification language. URM, together with contribution from Mentor Graphics' AVM, later became the OVM (Open Verification Methodology), and eventually becoming the UVM (Universal Verification Methodology).{{fact, date=September 2011 Further reading ...

E (verification Language)
e is a hardware verification language (HVL) which is tailored to implementing highly flexible and reusable verification testbenches. History ''e'' was first developed in 1992 in Israel by Yoav Hollander for his Specman software. In 1995 he founded a company, ''InSpec'' (later renamed Verisity), to commercialize the software. The product was introduced at the 1996 Design Automation Conference.Samir Palnitkar: ''Design verification with e'', Prentice Hall PTR. October 5, 2003. Verisity has since been acquired by Cadence Design Systems Cadence Design Systems, Inc. (stylized as cādence), headquartered in San Jose, California, is an American multinational corporation, multinational computational software company, founded in 1988 by the merger of SDA Systems and ECAD, Inc. The co .... Features Main features of ''e'' are: * Random and constrained random stimulus generation * Functional coverage metric definition and collection * Temporal language that can be used for writ ...

Universal Verification Methodology
The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from the OVM ( Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e Verification Language developed by Verisity Design in 2001. The UVM class library brings much automation to the SystemVerilog language such as sequences and data automation features (packing, copy, compare) etc., and unlike the previous methodologies developed independently by the simulator vendors, is an Accellera standard with support from multiple vendors: Aldec, Cadence, Mentor Graphics, Synopsys, Xilinx Simulator(XSIM). History In December 2009, a technical subcommittee of Accellera — a standards organization in the electronic design automation (EDA) industry — voted to establish the UVM and decided to base this new standard on the Open Verification Methodology (OVM-2.1.1), a verification methodology dev ...

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 ...

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between bracke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
