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 ...

Aspect-oriented Programming
In computing, aspect-oriented programming (AOP) is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns. It does so by adding behavior to existing code (an advice) ''without'' modifying the code, instead separately specifying which code is modified via a " pointcut" specification, such as "log all function calls when the function's name begins with 'set. This allows behaviors that are not central to the business logic (such as logging) to be added to a program without cluttering the code of core functions. AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while aspect-oriented software development refers to a whole engineering discipline. Aspect-oriented programming entails breaking down program logic into cohesive areas of functionality (so-called ''concerns''). Nearly all programming paradigms support some level of grouping and encapsulation of conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Test Bench
A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model. The term has its roots in the testing of electronic devices, where an engineer would sit at a lab bench with tools for measurement and manipulation, such as oscilloscopes, multimeters, soldering irons, wire cutters, and so on, and manually verify the correctness of the device under test (DUT). In the context of software or firmware or hardware engineering, a test bench is an environment in which the product under development is tested with the aid of software and hardware tools. The software may need to be modified slightly in some cases to work with the test bench but careful coding can ensure that the changes can be undone easily and without introducing bugs. The term "test bench" is used in digital design with a hardware description language to describe the test code, which instantiates the DUT and runs the test. An additional meaning for "test bench" is an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specman
Specman is an EDA tool that provides advanced automated functional verification of hardware designs. It provides an environment for working with, compiling, and debugging testbench environments written in the ''e'' Hardware Verification Language. Specman also offers automated testbench generation to boost productivity in the context of block, chip, and system verification. The Specman tool itself does not include an HDL simulator (for design languages such as VHDL or Verilog.) To simulate an e-testbench with a design written in VHDL/Verilog, Specman must be run in conjunction with a separate HDL simulation tool. Specman is a feature of Cadence's new Xcelium simulator, where tighter product integration offers both faster runtime performance and debugs capabilities not available with other HDL simulators. In principle, Specman can co-simulate with any HDL simulator supporting standard PLI or VHPI interface, such as Synopsys's VCS, or Mentor's Questa. History Specman was origina ...

Universal Verification Methodology
The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from 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 a framework and automation to the SystemVerilog language such as sequences and data automation features (packing, copy, compare) etc., and unlike the previous methodologies developed independently by EDA (Electronic Design Automation) Vendors, is an Accellera standard with support from multiple vendors: Aldec, Cadence, Mentor Graphics(Siemens), 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- ...

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of '' objects''. Objects can contain data (called fields, attributes or properties) and have actions they can perform (called procedures or methods and implemented in code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java, and Python) support object-oriented programming to a greater or lesser degree, typically as part of multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada, ActionScript, C++, Common Lisp, C#, Dart, Eiffel, Fortran 2003, Haxe, Java, JavaScript, Kotlin, Logo, MATLAB, Objective-C, Object Pascal, Perl, PHP, Python, R, Raku, Ruby, Scala, SIMSCRIPT, Simula, Smalltalk, Swift, Vala and Visual Basic.NET.

VHDL
VHDL (Very High Speed Integrated Circuit Program, VHSIC Hardware Description Language) is a hardware description language that can model the behavior and structure of Digital electronics, digital systems at multiple levels of abstraction, ranging from the system level down to that of logic gates, for design entry, documentation, and verification purposes. The language was developed for the US military Very High Speed Integrated Circuit Program, VHSIC program in the 1980s, and has been standardized by the Institute of Electrical and Electronics Engineers (IEEE) as IEEE Std 1076; the latest version of which is IEEE Std 1076-2019. To model Analogue electronics, analog and Mixed-signal integrated circuit, mixed-signal systems, an IEEE-standardized HDL based on VHDL called VHDL-AMS (officially IEEE 1076.1) has been developed. History In 1983, VHDL was originally developed at the behest of the U.S. Department of Defense in order to document the behavior of t ...

Verilog
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits, with the highest level of abstraction being at the register-transfer level. It is also used in the verification of analog circuits and mixed-signal circuits, as well as in the design of genetic circuits. In 2009, the Verilog standard (IEEE 1364-2005) was merged into the SystemVerilog standard, creating IEEE Standard 1800-2009. Since then, Verilog has been officially part of the SystemVerilog language. The current version is IEEE standard 1800-2023. Overview Hardware description languages such as Verilog are similar to software programming languages because they include ways of describing the propagation time and signal strengths (sensitivity). There are two types of assignment operators; a blocking assignment (=), and a non-blocking (>>. A generate–endgenerate construct (similar to V ...
