The recent rise of "smart" products has been made possible through tight co-design of hardware and software. In this book we dive deep into a key methodology to enable hardware/software co-design by decoupling the dependency of the software development from hardware availability: virtual prototyping. The ability to start software development much earlier in the design cycle drives a true "shift-left" of the entire product development schedule and results in better products that are available earlier in the market. Throughout the book case studies illustrate how virtual prototypes are being deployed by major companies around the world.
