Elements of VHDL for description of hardware: a tutorial view

An introduction to hardware description languages, a discussion of the emergence of VHDL as the standard HDL, and an overview of the VHDL language are given. The constructs of VHDL for design and modeling of hardware are emphasized. An overview of VHDL is given by use of a simple example which is broken into subcomponents, each of which is described at various levels of abstraction. Advanced features of VHDL are discussed, and corresponding examples are presented. These examples are used in the bottom-up design of a complete circuit
