Flow To HDL
Flow to HDL tools and methods convert flow-based system design into a hardware description language (HDL) such as VHDL or Verilog. Typically this is a method of creating designs for field-programmable gate array, application-specific integrated circuit prototyping and digital signal processing (DSP) design. Flow-based system design is well-suited to field-programmable gate array design as it is easier to specify the innate parallelism of the architecture. History The use of flow-based design tools in engineering is a reasonably new trend. Unified Modeling Language is the most widely used example for software design. The use of flow-based design tools allows for more holistic system design and faster development. C to HDL tools and flow have a similar aim, but with C or C-like programming languages. Applications Most applications are ones which take too long with existing supercomputer architectures. These include bioinformatics, CFD, financial processing and oil and gas s ...

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 ...

Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing Electronics, electronic systems such as integrated circuits and printed circuit boards. The tools work together in a Design flow (EDA), design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs). History Early days The earliest electronic design automation is attributed to IBM with the documentation of its IBM 700/7000 series, 700 series computers in the 1950s. Prior to the development of EDA, integrated circuits were designed by hand and manually laid out. Some advanced shops used geometric software to generate tapes for a Gerber format, Gerber photoplotter, responsible for generating a monochromatic ex ...

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] |
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 ...
