Hardware Verification Language
A hardware verification language, or HVL, is a programming language used to verify the designs of electronic circuits written in a hardware description language. HVLs typically include features of a high-level programming language like C++ or Java as well as features for easy bit-level manipulation similar to those found in HDLs. Many HVLs will provide constrained random stimulus generation, and functional coverage constructs to assist with complex hardware verification. SystemVerilog, OpenVera, e, and SystemC are the most commonly used HVLs. SystemVerilog attempts to combine HDL and HVL constructs into a single standard.

Electronic Circuits
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. It is a type of electrical circuit and to be referred to as ''electronic'', rather than ''electrical'', generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data can be moved from one place to another. Circuits can be constructed of discrete components connected by individual pieces of wire, but today it is much more common to create interconnections by photolithographic techniques on a laminated substrate (a printed circuit board or PCB) and solder the components to these interconnections to create a finished circuit. In an integrated circuit or IC, the components and interconnections are formed on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. It also allows for the synthesis of an HDL description into a netlist (a specification of physical electronic components and how they are connected together), which can then be placed and routed to produce the set of masks used to create an integrated circuit. A hardware description language looks much like a programming language such as C or ALGOL; it is a textual description consisting of expressions, statements and control structures. One important difference between most programming languages and HDLs is that HDLs explicitly include the notion of time. HDLs form an integral part of electr ...

High-level Programming Language
In computer science, a high-level programming language is a programming language with strong Abstraction (computer science), abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language ''elements'', be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is. In the 1960s, a high-level programming language using a compiler was commonly called an ''autocode''. Examples of autocodes are COBOL and Fortran. The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time, and his original contributions were largely isolated from other developments due to World War II, aside from th ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ... [...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 ...

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. 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 writing assertions * Aspect-oriented programming language with reflection capability * Language is DUT-neutral in that you can use a single ''e'' testbench to verify a SystemC/C++ model, an RTL model, a gate level model, or even a DUT residing in a hardware ...

Property Specification Language
Property Specification Language (PSL) is a temporal logic extending linear temporal logic with a range of operators for both ease of expression and enhancement of expressive power. PSL makes an extensive use of regular expressions and syntactic sugaring. It is widely used in the hardware design and verification industry, where formal verification tools (such as model checking) and/or logic simulation tools are used to prove or refute that a given PSL formula holds on a given design. PSL was initially developed by Accellera for specifying properties or assertions about hardware designs. Since September 2004 the standardization on the language has been done in IEEE 1850 working group. In September 2005, the IEEE 1850 Standard for Property Specification Language (PSL) was announced. Syntax and semantics PSL can express that if some scenario happens now, then another scenario should happen some time later. For instance, the property "a should always eventually be ed" can be expr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
