"…this book is surely welcome…due to its simple but efficient structure, the book can be used both in academia and in industry." (IEEE Circuits & Devices, July/August 2006) “...ideally suited for teaching digital hardware design techniques using a low-level programming language...highly recommended...” (Choice, Vol. 41, No. 8, April 2004)"…enables readers to master Verilog as an HDL for design...engages the readers at every stage through the variety and number of examples."
