This book deals with actual design applications rather than the technology of VLSI Systems. This book is written basically for an advanced level course in Digital VLSI Systems Design using a Hardware Design Language (HDL), V- ilog. This book may be used for teaching undergraduates, graduates, and research scholars of Electrical, Electronics, Computer Science and Engineering, Embedded Systems, Measurements and Instrumentation, Applied Electronics, and interdis- plinary departments such as Biomedical, Mechanical Engineering, Information Technology, Physics, etc. This book also serves as a reference design manual for practicing engineers and researchers. Although this book is written for an - vanced level course, diligent freelance readers, and consultants, especially, those who do not have a first level exposure of digital logic design, may also start using this book after a short term course or self-study on digital logic design. In order to help these readers as well as regular students, the book starts with a good review of digital systems design, which lays a solid foundation to understand the rest of this book right up to involved Project Designs unfolded gradually. Contents of the Book The book presents new source material and theory as well as synthesis of recent work with complete Project Designs using industry standard CAD tools and FPGA boards, enabling the serious readers to design VLSI Systems on their own.
