"Principles of Verifiable RTL Design 第二版是关于Verilog中的可验证寄存器传输级（RTL）设计的一本功能编码风格支持的书籍，由Lionel Bening和Harry Foster撰写，由KLUWER ACADEMIC PUBLISHERS出版。这本书对于IC设计行业的专业人士来说是一份推荐的阅读资料。" 正文: 《Principles of Verifiable RTL Design》第二版深入探讨了如何在数字电路设计中实现可验证的RTL代码，这是集成电路(IC)设计领域中的一个重要主题。RTL设计是IC设计流程的关键步骤，它涉及到用硬件描述语言如Verilog来编写电路逻辑的抽象表示。该书的核心目标是通过一种功能性编码风格来支持验证过程，帮助工程师编写出更易于验证和调试的代码。书中涵盖了多个关键知识点，包括： 1. **验证的重要性**：验证是确保设计正确性的关键步骤，尤其是在复杂的IC设计中，错误可能导致高昂的成本和时间损失。该书强调了在RTL阶段就采用可验证设计方法的重要性。 2. **功能性编码风格**：作者介绍了如何采用特定的编程习惯和结构，使得代码更容易被形式验证工具处理，从而提高验证效率和覆盖率。 3. **Verilog语言特性**：书中详细讲解了Verilog的各种语言元素，如模块、赋值语句、条件语句、循环以及接口等，以及如何有效地利用这些特性来实现可验证的设计。 4. **验证方法学**：包括使用基于断言的验证、测试平台的构建、覆盖率度量和激励生成等，这些都是现代IC设计验证的重要组成部分。 5. **设计与验证的交互**：书中讨论了如何将设计过程与验证过程紧密结合，以减少设计迭代次数和提升整体设计质量。 6. **案例研究**：通过具体的实例，读者可以学习到如何应用这些原则解决实际设计问题，加深对理论知识的理解。 7. **工具和技术**：书中可能会涉及一些常用的验证工具，如仿真器、形式验证工具和覆盖率分析工具，以及如何利用它们进行有效的RTL验证。 8. **最佳实践**：作者分享了他们在HP公司的经验，提出了一套实用的设计和验证最佳实践，有助于读者在实际工作中避免常见错误。这本书不仅适合初学者了解RTL设计和验证的基本概念，也适合有经验的工程师深入学习和提升验证技能。通过阅读此书，读者能够掌握一套完整的、支持验证的RTL设计方法，从而提高其在IC设计领域的专业能力。

FOREWORD

System designers, computer scientists and engineers have con-

tinuously invented and employed notations for modeling, specify-

ing, simulating, documenting, communicating, teaching, verifying

and controlling the designs of digital systems. Initially these sys-

tems were represented via electronic and fabrication details. Fol-

lowing C. E. Shannon’s revelation of 1948, logic diagrams and

Boolean equations were used to represent digital systems in a fash-

ion that de-emphasized electronic and fabrication detail while

revealing logical behavior. A small number of circuits were made

available to remove the abstraction of these representations when it

was desirable to do so. As system complexity grew, block diagrams,

timing charts, sequence charts, and other graphic and symbolic

notations were found to be useful in summarizing the gross features

of a system and describing how it operated. In addition, it always

seemed necessary or appropriate to augment these documents with

lengthy verbal descriptions in a natural language.

While each notation was, and still is, a perfectly valid means of

expressing a design, lack of standardization, conciseness, and for-

mal definitions interfered with communication and the understand-

ing between groups of people using different notations. This

problem was recognized early and formal languages began to

evolve in the 1950s when I. S. Reed discovered that flip-flop input

equations were equivalent to a register transfer equation, and that

tor-like notation. Expanding these concepts Reed developed a nota-

tion that became known as a Register Transfer Language (RTL).

While the notation had only a few features that are associated with

RTLs today, its development started an evolutionary process that is

still underway. RTLs such as Verilog improve the ability of the

designer to communicate the design intent as well as providing a

mechanism to verify correctness.

In the late 1980s, progress in RTL synthesis provided productiv-

ity gains by translating the designer’s intent into gates and silicon.

Success with RTL synthesis resulted in the acceptance of an RTL

synthesizable subset. In other words, by constraining a rich RTL to

a subset of keywords and an explicit coding style, synthesis can use

precise semantics to provide an efficient and clear mapping to a

specific hardware implementation.

Unfortunately, the synthesis productivity gain has resulted in an

increase in verification complexity. In this book, the focus is on ver-

ification productivity gains. This seems to be a normal progression

to emphasize synthesis productivity gains when synthesis was in

the critical path, and then turn to verification productivity gains

when it became the biggest problem for the design team. This book

promotes a strong coupling between the RTL specification and the

verification process. The authors have placed emphasis on describ-

ing verification processes and explicitly how

they relate to RTL

coding style. Many other Verilog books describe details for the

entire language without considering the coding impact related to

the verification process.

By constraining a rich hardware description language to an RTL

verifiable subset, emerging verification technologies can easily be

integrated into the design flow (e.g., model checking, equivalence

checking, cycle-based simulation and fast two-state simulation).

The RTL verifiable subset in this book is actually a smaller synthe-

sizable subset, which includes the keywords supporting higher lev-

els of modeling and abstraction. Some Hewlett-Packard engineers

outside the authors’ team have found the ideas too revolutionary,

and out-of-line with the way that they learned to use Verilog for

simulation and synthesis. However, the authors’ team has success-

fully developed very large complex systems in Hewlett-Packard fol-

lowing the guidelines and methodologies discussed in this book.

Furthermore, the authors’ team has successfully integrated emerg-

ing verification technologies into their design flow, while other

design teams are struggling and fighting the verification tools and

processes.

I find this book to be a significant contribution in helping other
