Very-high-speed hardware description language (Vhdl) has been at the heart of electronic design productivity since its initial ratifcation by the Institute of Electrical and Electronics Engineers (IEEE) in 1987. For almost 15 years, the electronic design automation industry has expanded the use of VHDL from the initial concept of design documentation to design implementation and functional verifcation. It can be said that VHDL fuelled modern synthesis technology and enabled the development of application-specifc integrated circuit (asic) semiconductor ndustries. The use of VHDL has evolved and its importance increased as semiconductor device dimensions have shrunk. A major revolution in digital design has taken place over the past decade. Field-programmable gate arrays (FPGAs) can now contain over millions of millions of equivalent logic gates and tens of thousands of flip-flops. This means that it is not necessary to use traditional methods of logic design involving the drawing of logic diagrams when the digital circuit may contain thousands of gates.
