Prof. Volnei Pedroni's VHDL textbook gained popularity more than a decade ago - and it was an excellent and clear textbook indeed. However, in this third edition, Pedroni made a very big improvement over that: he added four chapters that focus solely on RTL design and are not language-specific. First, it makes the book much more convenient to study with, since it allows the exercises to refer directly to the circuits they mean. And second, those chapters contain information that is, in fact, rarely found elsewhere - for example, the chapter on finite state machines is a summary of Prof. Pedroni's entire book on them - and it shows the reader types of state machines and design methods for them that are almost never found in other textbooks (such as the true advantage of Mealy over Moore, or recursive FSMs).Speaking of the VHDL part, which, of course, comprises most of the book, it is great as usual - especially the exercises, that are truly enjoyable to do.
