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] |
SystemC AMS
SystemC AMS is an extension to SystemC for analog, mixed-signal and RF functionality. The SystemC AMS 2.0 standard was released on April 6, 2016 as IEEE Std 1666.1-2016. Language specification ToDo: description Language features ToDo: description MoC - Model of Computation A ''model of computation'' (MoC) is a set of rules defining the behavior and interaction between SystemC AMS primitive modules. SystemC AMS defines the following models of computation: timed data flow (TDF), linear signal flow (LSF) and electrical linear networks (ELN). TDF - Timed Data Flow In the timed data flow (TDF) model, components exchange analogue values with each other on a periodic basis at a chosen sampling rate, such as every 10 microseconds. By the sampling theorem, this would be sufficient to convey signals of up to 50 MHz bandwidth without aliasing artefacts. A TDF model defines a method called `processing()' that is invoked at the appropriate rate as simulation time advances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-level Synthesis
High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior. Synthesis begins with a high-level specification of the problem, where behavior is generally decoupled from low-level circuit mechanics such as clock-level timing. Early HLS explored a variety of input specification languages,IEEE XplorHigh-Level Synthesis: Past, Present, and FutureDOI 10.1109/MDT.2009.83 although recent research and commercial applications generally accept synthesizable subsets of ANSI C/ C++/ SystemC/MATLAB. The code is analyzed, architecturally constrained, and scheduled to transcompile from a transaction-level model (TLM) into a register-transfer level (RTL) design in a hardware description language (HDL), which is in turn common ...

Transaction-level Modeling
Transaction-level modeling (TLM) is an approach to modelling complex digital systems by using electronic design automation software. TLM language (TLML) is a hardware description language, usually, written in C++ and based on SystemC library. TLMLs are used for modelling where details of communication among modules are separated from the details of the implementation of functional units or of the communication architecture. It's used for modelling of systems that involve complex data communication mechanisms. Components such as buses or FIFOs are modeled as channels, and are presented to modules using SystemC interface classes. Transaction requests take place by calling interface functions of these channel models, which encapsulate low-level details of the information exchange. At the transaction level, the emphasis is more on the functionality of the data transfers – what data are transferred to and from what locations – and less on their actual implementation, that is, on th ...

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, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs). A hardware description language enables a precise, Formal language, formal description of an electronic circuit that allows for the automated analysis and Electronic circuit simulation, simulation of the circuit. It also allows for the Logic synthesis, synthesis of an HDL description into a netlist (a specification of physical electronic components and how they are connected together), which can then be Place and route, placed and routed to produce the Mask set, set of masks used to create an integrated circuit. A hardware description language looks much like a programming language such as C (programming language), C or ALGOL; it is a textual description consisting of expressions, statements and c ...

Accellera
Accellera Systems Initiative (Accellera) is a standards organization that supports a mix of user and vendor standards and open interfaces development in the area of electronic design automation (EDA) and integrated circuit (IC) design and manufacturing. It is less constrained than the Institute of Electrical and Electronics Engineers (IEEE) and is therefore the starting place for many standards. Once mature and adopted by the broader community, the standards are usually transferred to the IEEE. History In 2000, Accellera was founded from the merger of Open Verilog International (OVI) and VHDL International, the developers of Verilog and VHDL respectively. Both were originally formed nine years earlier in 1991. In June 2009, a merger was announced between Accellera and The SPIRIT Consortium, another major EDA standards organization focused on IP deployment and reuse. The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance and then developed IP-XACT. The merger was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic System-level
Electronic system level (ESL) design and verification is an electronic design methodology, focused on higher abstraction level concerns. The term ''Electronic System Level'' or ''ESL Design'' was first defined by Gartner Dataquest, an EDA-industry-analysis firm, on February 1, 2001. It is defined in ''ESL Design and Verification'' as: "the utilization of appropriate abstractions in order to increase comprehension about a system, and to enhance the probability of a successful implementation of functionality in a cost-effective manner." The basic premise is to model the behavior of the entire system using a low-level language such as C, C++, or using graphical "model-based" design tools. Newer languages are emerging that enable the creation of a model at a higher level of abstraction including general purpose system design languages like SysML as well as those that are specific to embedded system design like SMDL and SSDL. Rapid and correct-by-construction implementation of the sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forte Design Systems
Forte Design Systems, Inc. was a San Jose, CA, based provider of high-level synthesis (HLS) software products, also known as electronic system-level (ESL) synthesis.

SpecC
SpecC is a System Description Language (SDL), or System-level Design Language (SLDL), and is an extension of the ANSI C programming language. It is used to aid the design and specification of digital embedded systems, providing improved productivity whilst retaining the ability to change a design at functional and specification level, unlike HDLs like Verilog and VHDL. An architectural model can be created which allows other tools to directly map the design onto silicon or FPGA. The main aim is for the reuse, exchange and integration of IP at various levels of abstraction. The language and design methodology were created by Rainer Dömer and Daniel Gajski at the Centre for Embedded Computer Systems at University of California, Irvine in 2001. Similar projects and design methodologies include SystemC, an SDL based on C++. Although this rival language has seen much more widespread industry usage (although SpecC is popular in Japan), SpecC retains simplicity whilst also providing ...

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 ...
