xi About the author Ronald W. Mehler Ronald Mehler is a professor of electrical and computer engineering at California State University, Northridge. Prior to joining the faculty of CSUN, he worked as an engineer for several companies, primarily designing digital-integrated circuits for aviation, telecommunications, and general-purpose computing applications. He has been designing integrated circuits with hardware description languages since 1988. He holds a B.S. in electrical and computer engineering from the University of Wisconsin, an M.S. in electrical engineering from Texas A&M University, and a Ph.D. in electrical engineering from the University of Texas at Dallas.
xiii Preface This is a book about using Verilog and SystemVerilog to design digital-integrated circuits. It takes the readers from the most fundamental elements of digital design through the design of sophisticated components and interfaces. Included are guide- lines for optimizing designs and creating robust, reliable systems. Digital-integrated circuits are the electronic brains behind all modern electronics. Communications, computers, aviation, automobiles, consumer appliances, and much more: if it runs on electricity, it has digital-integrated circuits someplace in the background. All modern digital circuits are designed with a hardware descrip- tion language, and Verilog/SystemVerilog is the engineer’s choice for the majority of new designs. Beyond simply a language reference manual, this book not only teaches the syntax of Verilog/SystemVerilog hardware description language, it teaches how to effec- tively use it to produce optimized circuits that will work the first time, every time. It contains little-understood information on asynchronous interfaces, a common source of failure in digital designs, and a guide to design partitioning to produce optimal designs. While no prior exposure to any hardware description language is expected, readers should have some basic knowledge of Boolean algebra and electrical engineering fundamentals such as Ohm’s law. This book is based on courses taught by the author at California State University. The courses are themselves based on the author’s 20 years of experience in private industry designing digital circuits prior to joining the CSU faculty.
