Computer Aided Design (CAD) is today a widely used expression referring to the study of ways in which computers can be used to expedite the design process. This can include the design of physical systems, architectural environments, manufacturing processes, and many other areas. This book concentrates on one area of CAD: the design of computer systems. Within this area, it focusses on just two aspects of computer design, the specification and the simulation of digital systems. VLSI design requires support in many other CAD areas, including automatic layout, IC fabrication analysis, test generation, and others. The problem of specification is unique, however, in that it is often the first one encountered in large chip designs, and one that is unlikely ever to be completely automated. This is true because until a design’s objectives are specified in a machine-readable form, there is no way for other CAD tools to verify that the target system meets them. And unless the specifications can be simulated, it is unlikely that designers will have confidence in them, since specifications are potentially erroneous themselves. (In this context the term target system refers to the hardware and/or software that will ultimately be fabricated.)
