VHDL has been at the heart of electronic design productivity since initial ratification by the IEEE in 1987. For almost 15 years the electronic design automation industry has expanded the use of VHDL from initial concept of design documentation, to design implementation and functional verification. It can be said that VHDL fueled modern synthesis technology and enabled the development of ASIC semiconductor companies. The editions of Doug Perry’s books have served as the authoritative source of practical information on the use of VHDL for users of the language around the world
