The skills and guidance needed to master RTL hardware design This book teaches readers how to systematically design efficient, portable, and scalable Register Transfer Level (RTL) digital circuits using VHDL hardware description language and synthesis software. The focus on design-level module, which consists of functional units, routing circuit, and storage, this book describes the relationship between VHDL construction and the underlying hardware components, and shows how to develop codes that faithfully reflect the module design level and can be synthesized into efficient gate-level implementation. Several unique features distinguish this book: * Coding style that shows a clear relationship between VHDL construction and hardware components * Conceptual diagrams that illustrate the realization of VHDL codes * Emphasis on reuse of code * Practical examples demonstrate and reinforce design concepts, procedures, and techniques * Two chapters on realizing sequential algorithms in hardware * Two chapters on scalable and parameter design and coding * One chapter covering the synchronization and interface between multiple clock domains Although the focus of this book is RTL synthesis, also examines the synthesis task from the perspective of overall development process.
