Knowing Verilog, I must disagree. Although it would be more beneficial if the book focused on hardware, its primary goal is to teach something other than hardware-specific definitions. HDL serves as a bridge to illustrate communication with predefined logic gates.
The book should include a mention or an appendix to clarify its real-world applications. By the end of chapter five, I was dissatisfied, feeling a lack of control over the crucial aspects of the hardware I just built. However, a book can only do justice to some of the missing pieces of information we have.
