The Verilog language is a hardware description language which provides a means of specifying a digital system at a wide range of levels of abstraction. The language supports the early conceptual stages of design with its behavioral level of abstraction, and the later implementation stages with its structural level of abstraction. The language provides hierarchical constructs, allowing the designer to control the complexity of a description. Verilog was originally designed in the winter of 1983/84 as a proprietary verification/simulation product. Since then, several other proprietary analysis...

Recently there has been increased interest in the development of computer-aided design programs to support the system level designer of integrated circuits more actively. Such design tools hold the promise of raising the level of abstraction at which an integrated circuit is designed, thus releasing the current designers from many of the details of logic and circuit level design. The promise further suggests that a whole new group of designers in neighboring engineering and science disciplines, with far less understanding of integrated circuit design, will also be able to increase their...
