SystemVerilog DPI
SystemVerilog DPI (Direct Programming Interface) is an interface which can be used to interface SystemVerilog with foreign languages. These foreign languages can be C, C++, SystemC as well as others. DPIs consist of two layers: a SystemVerilog layer and a foreign language layer. Both the layers are isolated from each other. Explanation Direct Programming Interface (DPI) allows direct inter language function calls between the SystemVerilog and Foreign language. The functions implemented in Foreign language can be called from SystemVerilog and such functions are called Import functions. Similarly, functions implemented in SystemVerilog can be called from Foreign language (C/C++ or System C); such functions are called Export functions. DPIs allow transfer of data between two domains through function arguments and return. Function import and export 1) Function Import:- A function implemented in Foreign language can be used in SystemVerilog by importing it. A Foreign language functi ...

SystemVerilog
SystemVerilog, standardized as IEEE 1800 by the Institute of Electrical and Electronics Engineers (IEEE), is a hardware description and hardware verification language commonly used to model, design, simulate, test and implement electronic systems in the semiconductor and electronic design industry. SystemVerilog is an extension 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 SystemVerilog standard was subsequently updated in 2012, 2017, and most recently in December 2023. in this case) which is used to represent the enumeration value.

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

SystemC
SystemC is a set of C++ classes and macros which provide an event-driven simulation interface (see also discrete event simulation). These facilities enable a designer to ''simulate'' concurrent processes, each described using plain C++ syntax. SystemC processes can communicate in a ''simulated'' real-time environment, using signals of all the datatypes offered by C++, some additional ones offered by the SystemC library, as well as user defined. In certain respects, SystemC deliberately mimics the hardware description languages VHDL and Verilog, but is more aptly described as a ''system-level modeling language''. SystemC is applied to system-level modeling, architectural exploration, performance modeling, software development, functional verification, and high-level synthesis. SystemC is often associated with electronic system-level (ESL) design, and with transaction-level modeling (TLM). Language specification SystemC is defined and promoted by the Open SystemC Initiativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Programming Interfaces
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that portion of the API. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
