This introductory manual presents a perspective on digital design at the system level and provides the tools needed for the student to understand, analyze, and design digital systems. It is not limited to the design of simple combinational and sequential subunits but also shows how these subunits are used to construct complex systems. It covers all the fundamental knowledge elements required to understand modern design practice, including: • the design and analysis of combinational and sequential subunits • the synthesis of combinational and sequential subunits • data and control partitioning • the segmentation and synthesis of finite state machines • interface specifications • system timing • synchronization It teaches Verilog coding in a way that ensures high productivity and ease of maintenance, allowing the designer to offload much of the more tedious tasks to CAD tools. It covers the fundamental concepts of logic design, presenting an efficient method for designing combinational logic and state machines, both manually and using modern CAD tools. The book provides a complete introduction to digital design through precise and clear explanations, extensive examples, and online Verilog code files. The teaching material is supplemented with lecture slides and workshops. Without any prerequisite knowledge of digital concepts, this manual is ideal for undergraduate digital design courses that will familiarize students with modern digital practice.
