Features: The outline of this book was reviewed and valuable suggestions were provided by Professor Xie Yuezhen of Beijing University of Posts and Telecommunications. The author expresses sincere gratitude. Special thanks are given to Professors Shen Sichang and Jiang Xuan for pioneering the research and teaching of EDA at Nanjing University of Aeronautics and Astronautics. Due to the limited level of the authors, there may inevitably be errors and shortcomings in the book, and the author sincerely invites readers to point out any mistakes. This book is not limited to the introduction and use of EDA software, but emphasizes the systematic and comprehensive nature of EDA technology, providing a relatively thorough explanation from theory, methods to tools. The main content includes the principles of simulation for analog and digital circuits, programmable analog and digital devices, the principles of printed circuit board design, as well as the design technology of application-specific integrated circuits (ASICs). It also introduces the practical use methods of relevant EDA tools such as Multisim, MAX+plusII, PAC-Designer, Protel99, and Microwind, enabling readers to fully understand and master common EDA technologies and tools. This book can be used as a textbook for communication and information engineering majors in universities and colleges, as well as a practical reference book and training manual for related engineering and technical personnel. Electronic Design Automation (EDA) is a broad concept, and any step in the electronic design process that uses computer-aided means can be considered part of EDA. Currently, EDA technology has received high attention and is widely applied, continuously developing in depth and breadth. The design of electronic systems can no longer be separated from the support of EDA tools, and its dependence is becoming increasingly strong. Mastering EDA technology has become a basic skill in electronic design. Therefore, it is quite important to carry out teaching related to EDA technology. The design of electronic systems is divided into multiple levels, from top to bottom: system level (algorithm level), functional level [register transfer level (RTL)], logic (gate) level, circuit level, and physical level (layout level). The design process of electronic systems includes three major aspects: design, verification, and implementation, and EDA technology has developed around these aspects. Simulation (also known as modeling) is the first EDA technology to emerge to meet the verification of electronic systems. The simulation of electronic systems is the use of computers to mimic the actual operation of electronic systems. Simulation helps to identify design errors before lower-level design or circuit fabrication, saving time and avoiding economic losses. The development of integrated circuit (IC) technology has brought significant changes to the implementation methods of electronic systems. Before the 1960s, electronic systems were composed of discrete components; in the 1960s and 1970s, electronic systems primarily used general-purpose integrated circuits; in the 1980s and 1990s, electronic systems gradually adopted semi-custom application-specific integrated circuits (ASICs) and programmable devices; entering the 21st century, full-custom and custom ASICs have become new development hotspots. The design and application of ASICs must rely on specialized EDA tools. Synthesis, also known as integration, is a method of automatic design by computers. The synthesis of electronic systems involves converting higher-level descriptions into a unified entity composed of lower-level modules that are easier to implement. The emergence of EDA synthesis tools has allowed designers to focus their main efforts on system-level design and optimization, freeing them from complex low-level design, thereby significantly improving design efficiency. The implementation of electronic systems, in addition to device support, also requires the fabrication of printed circuit boards (PCBs), making PCB design and fabrication another aspect of EDA technology. This textbook focuses on the main fields of EDA technology: simulation, synthesis, and implementation, emphasizing the systematic nature of EDA technology and providing a relatively comprehensive explanation from theory, methods to tools. To reflect the full picture of EDA technology, this book discusses the simulation, synthesis, and various common implementation methods at all levels of electronic systems. The book is divided into four parts. Part 1, consisting of Chapters 1 and 2, discusses electronic system simulation. It includes computer-aided analysis of analog circuits, logical simulation of digital circuits, mixed-signal simulation, component models, and the application of circuit simulation tool Multisim. Part 2, consisting of Chapters 3 and 4, discusses programmable devices. It includes programmable logic devices (CPLDs and FPGAs) and their development platform MAX+plusII, programmable analog circuits (PAC) and their development tool PAC-Designer, and a brief introduction to mixed-signal programmable single-chip systems. Part 3, consisting of Chapter 5, introduces the composition and design methods of printed circuit boards, automatic layout and routing, as well as the use of PCB design tool Protel99SE. The last two chapters form Part 4, introducing integrated circuit manufacturing processes, full-custom circuit design methods and processes, and the use of teaching-oriented integrated circuit design tool Microwind. Each chapter is accompanied by quantitative exercises to consolidate learned concepts and master corresponding EDA tools. In addition to conceptual questions, most design questions require the use of EDA tools for design description and verification of design correctness. If conditions permit, design questions related to programmable devices can also be downloaded and implemented. The authors of this book referred to a large number of EDA literature and cited the research results of some experts and scholars to strive for content that is novel, rich, and practical, such as mixed-signal simulation technology, the latest programmable devices, and mixed-signal programmable single-chip systems, as well as integrated circuit design tools. In the explanation of EDA tools, emphasis is placed on key and difficult points, and typical examples are used to guide readers to quickly get started. The logic symbols used in this book are part of the internationally popular symbols, and their correspondence to national standards in China can be found in the appendix.
