Digital Design and Verilog HDL Fundamentals
Comprehensive and self contained, this tutorial covers the design of a plethora of combinational and sequential logic circuits using conventional logic design and Verilog HDL. Number systems and number representations are presented along with various binary codes. Several advanced topics are covered, including functional decomposition and iterative networks. A variety of examples are provided for combinational and sequential logic, computer arithmetic, and advanced topics such as Hamming code error correction. Constructs supported by Verilog are described in detail. All designs are continued to completion. Each chapter includes numerous design issues of varying complexity to be resolved by the reader.
Why Read This Book
You will get a hands-on, example-driven introduction to both classical digital logic and Verilog HDL so you can move from truth tables and FSM diagrams to synthesizable code. The book emphasizes end-to-end designs and exercises, so you’ll practice completing real combinational and sequential circuits in Verilog.
Who Will Benefit
Undergraduate students, new FPGA/ASIC engineers, and hobbyists who need a structured introduction to digital logic and Verilog with worked examples and exercises.
Level: Beginner — Prerequisites: Basic algebra and Boolean logic; no prior HDL experience required (some familiarity with digital concepts helps).
Key Takeaways
- Describe and use binary number systems, two's complement, and common binary codes.

How It Compares
Covers the same foundational logic material as M. Morris Mano but pairs it with more Verilog coding practice; compared with Samir Palnitkar's Verilog book, Cavanagh focuses more on digital-design fundamentals and worked examples than being a Verilog language reference.
