Abstract: Field Programmable Gate Array (FPGAs) are usually programmed using languages and methods inherited from the domain of VLSI (Very Large Scale Integration) synthesis. These methods, however, have not always been adapted to the new possibilities opened by FPGA, nor to the new constraints do they impose on a design. For FPGA circuit we can use the VHDL language as hardware description (acronym for Very High Speed Integrated Circuits Hardware Description Language). The key of the art design is focused around high level synthesis which is a top down design methodology that transforms an abstract level using VHDL description. the synthesis tools allow designers to realize the mainly reasons: the need to get a correctly working systems at the first time, technology independent design, design reusability, the ability to experiment with several alternatives of the design, and economic factors such as time to market. VHDL allows for the description of hardware behavior from !
system to gate levels . To fit this level of description, the language has to offer lager degrees of abstraction, powerful algorithmic, wide capabilities for merging different description levels, and an easiness expression of causality, and also the possibility of introducing non determinism, which may be an interesting feature. To date, this level of description has not been synthesizable: no explicit architecture is described and no tool on the market offers a real and an efficient architectural synthesis (except for some specific target architecture. In this paper we present some useful notes of VHDL: main hardware concept of VLSI.
