This book describes the structure of simulators suitable for use in the design of digital electronic systems. Such systems are increasing rapidly in size and complexity, and the use of simulation provides a means to 'prototype' a design without ever building hardware. Other advantages over hardware prototyping are that sections of a design can be simulated in isolation, and that all internal signals are available.
This book includes the compiled code and event driven algorithms for digital electronic system simulators, together with timing verification. Limitations of the structures are also discussed. An introduction to the
problems of designing models is included, partly to point to how user models might be constructed for application specific integrated circuits (ASICs) and so on, and partly to expose the limitations of the modelling process.
