Opis

by Phil Moorby The Verilog Hardware Description Language has had an amazing impact on the mod- em electronics industry, considering that the essential composition of the language was developed in a surprisingly short period of time, early in 1984. Since its introduc- tion, Verilog has changed very little. Over time, users have requested many improve- ments to meet new methodology needs. But, it is a complex and time consuming process to add features to a language without ambiguity, and maintaining consistency. A group of Verilog enthusiasts, the IEEE 1364 Verilog committee, have broken the Verilog feature doldrums. These individuals should be applauded. They invested the time and energy, often their personal time, to understand and resolve an extensive wish-list of language enhancements. They took on the task of choosing a feature set that would stand up to the scrutiny of the standardization process. I would like to per- sonally thank this group. They have shown that it is possible to evolve Verilog, rather than having to completely start over with some revolutionary new language. The Verilog 1364-2001 standard provides many of the advanced building blocks that users have requested. The enhancements include key components for verification, abstract design, and other new methodology capabilities. As designers tackle advanced issues such as automated verification, system partitioning, etc., the Verilog standard will rise to meet the continuing challenge of electronics design.

Recenzje

`Mr. Sutherland was one of the principal engineers involved with the creation of the Verilog-2001 standard. The insights he provides in this book are a valuable resource for anyone seeking to understand these latest enhancements to the Verilog language.'
Phil Moorby, Co-design Automation, Inc.
`Stuart has done an outstanding job of explaining in detail all the new features of Verilog 2001. His book is very well written, easy to read and should serve as an invaluable supplement to the actual IEEE 1364-2001 standard.'
Maq Mannan, DSM Technologies and Chair, IEEE 1364 Standards Group
`This book is a must read for anyone who wants to use and take advantage of all the new powerful features in Verilog 2001. Mr Sutherland clearly describes all new constructs and compares them with the previous Verilog 1995 standard. His description of advantages of the new constructs and potential pitfalls is particularly useful when getting up to speed with Verilog 2001.'
Anders Nordstrom, Nortel Networks, Ltd.
`This book provides an excellent overview an explanation of the new Verilog 2001 features, the rationale for each new feature, and examples. Users of the new standard will find this book beneficial and easy to read.'
Ben Cohen, Publisher, Trainer, Consultant
`This book is a must-have for any Verilog programmer who wants to keep in touch with the latest developments in the language. [...]it could also serve as a good reference for beginners who can take advantage of the new features and adopt a muxch advanced coding style.'
IEEE Circuits & Devices Magazine, September 2003
