Advanced Digital Design with the Verilog HDL, 2e, is ideal for an advanced course in digital design for seniors and first-year graduate students in electrical engineering, computer engineering, and computer science.
The widely used Verilog hardware description language (IEEE Standard 1364) serves as a common framework supporting the design activities treated in this book, but our focus is on developing, verifying, and synthesizing designs of digital circuits, not on the Verilog language. Most students taking a second course in digital design will be familiar with at least one programming language and will be able to draw on that background in reading this textbook. We cover only the core and most widely used features of Verilog. In order to emphasize using the language in a synthesis-oriented design environment, we have purposely placed many details, features, and explanations of syntax in the Appendices for reference on an \"as-needed\" basis.
Most entry-level courses in digital design introduce state machines, state-transition graphs, and algorithmic-state machine (ASM) charts. We make heavy use of ASM charts and demonstrate their utility in developing behavioral models of sequential machines. The important problem of designing a finite-state machine to control a complex datapath in a digital machine is treated in-depth with ASMD charts (i.e., ASM charts annotated to display the register operations of the controlled datapath). The design of a reduced instruction-set computer central processing unit (RISC CPU) and other important hardware units are given as examples. Our companion website includes the RISC machine's source code and an assembler that can be used to develop programs for applications. The machine also serves as a starting point for developing a more robust instruction set and architectural variants.
This book is for students in an advanced course in digital design, and for professional engineers interested in learning Verilog by example, in the context of its use in the design flow of modern integrated circuits. The level of presentation is appropriate for seniors and first-year graduate students in electrical engineering, computer engineering, and computer science, as well as for professional engineers who have had an introductory course in logic design. The book presumes a basic background in Boolean algebra and its use in logic circuit design and a familiarity with finite-state machines. Building on this foundation, the book addresses the design of several important circuits used in computer systems, digital signal processing, image processing, data transfer across clock domains, built-in self-test (BIST), and other applications. The book covers the key design problems of modeling, architectural tradeoffs, functional verification, timing analysis, test generation, fault simulation, design for testability, logic synthesis, and postsynthesis verification.
Chapter 1 briefly discusses the role of HDLs in design flows for cell-based ASICs and FPGAs. Chapters 2 and 3 review mainstream topics that would be covered in a first course in digital design, using classical methods (i.e. Karnaugh maps). This material will refresh the reader's background, and the examples will be used later to introduce HDL-based methods of design. Chapters 4 and 5 introduce modeling of combinational and sequential logic with the Verilog HDL, and place emphasis on coding styles that are used in behavioral modeling. Chapter 6 addresses cell-based synthesis of ASICs, and introduces synthesis of combinational and sequential logic. Here we pursue two main objectives: (1) present synthesis-friendly coding styles, and (2) form a foundation that will enable the reader to anticipate the results of synthesis, especially when synthesizing sequential machines. Many sequential machines are partitioned into a datapath and a controller. Chapter 7 covers examples that illustrate how to design a controller for a datapath. The designs of a simple RISC CPU and a UART serve as platforms for the subject matter. Chapter 8 covers PLDs, complex PLDs (CPLDs), ROMs, and static random-access memories (SRAMs), then expands the synthesis target to include FPGAs. Verilog has been used extensively to design computers and signal processors. Chapter 9 treats the modeling and synthesis of computational units and algorithms found in computer architectures, digital filters, and other processors. Chapter 10 develops and refines algorithms and architectures for the arithmetic units of digital machines. In Chapter 11 we use the Verilog HDL in conjunction with fault simulators and timing analyzers to revisit a selection of previously designed machines and consider performance/timing issues and testability...
