A hands-on approach to teaching Digital Design that combines theory and practice

Digital Design emphasizes a top-down behavior-to-circuits perspective, for combinational, sequential, and high-level (register-transfer-level) design. The book’s HDL (Verilog and VHDL) coverage is intentionally template focused, teaching just enough of the HDLs to understand the templates. Includes:

  • Web-based simulators, including circuit, finite-state machine, high-level state machine, and datapath simulators
  • Hands-on learning tools, including Boolean algebra solver, K-map minimizer, state machine capture, and more
  • Hundred of participation activities, including questions, animations and auto-graded challenge activities

Ideal book for a traditional “what’s under the hood” goal as well as for an introduction to embedded systems. Now with Verilog labs.

Emphasis on RTL design

Director of Content Authoring and Research Dr. Yamuna Rajasekhar explains how the Digital Design zyBook provides students with a crucial, real-world understanding of RTL design:

What is a zyBook?

Digital Design is a web-native, interactive zyBook that helps students visualize concepts to learn faster and more effectively than with a traditional textbook. (Check out our research.)

Since 2012, over 1,200 universities and colleges across the country have adopted digital zyBooks to transform their STEM education.

zyBooks benefit both students and instructors:

  • Instructor benefits
  • Customize your course by reorganizing existing content, or adding your own content
  • Continuous publication model updates your course with the latest content and technologies
  • Robust reporting gives you insight into students’ progress, reading and participation
  • Save time with auto-graded labs and challenge activities that seamlessly integrate with your LMS gradebook
  • Build quizzes and exams with hundreds of included test questions
  • Student benefits
  • Learning questions and other content serve as an interactive form of reading
  • Instant feedback on labs and homework
  • Concepts come to life through extensive animations embedded into the interactive content
  • Review learning content before exams with different questions and challenge activities
  • Save chapters as PDFs to reference the material at any time
