Virtual platforms are widely used in both pre- and post-silicon development of computer software and systems. They shorten time-to-market, improve system quality, make development more efficient, and enable truly parallel hardware/software design and deployment. Virtual platforms enhance productivity through unparalleled inspection, configuration, and injection capabilities. In combination with other types of simulators, they provide complete system simulations, where computer systems are tested alongside the environment in which they operate. This book not only discusses what simulation is and why it is important, but it also covers the methodology for building and using simulators for computer-based systems. Inside, you will find a comprehensive guide to best practices and design patterns for simulations, using Simics as a foundation, along with practical examples to help you get the most out of your Simics.
