If you are a manager looking to learn about what VHDL is used for, perhaps this book would help. If you really need to learn VHDL, this book is a let down. The code samples use constructs that are never explained, key topics for real chip design are never discussed, if you will be trying to do something that is not identical to the examples you'll need another book to understand them (A Guide to VHDL Syntax - Bhaskar, at least) If you do buy this book, treat it well, you'll want to try to return it.
