Hdl Chip Design

This book concentrates on common classes of hardware architectures and design problems, and focuses on the process of transitioning design requirements into synthesizable HDL code. Using his extensive, wide-ranging experience in computer architecture and hardware design, as well as in his training and consulting work, Ben provides numerous examples of real-life designs illustrated with VHDL and Verilog code. This code is shown in a way that makes it easy for the reader to gain a greater understanding of the languages and how they compare. All code presented in the book is included on the companion CD, along with other information, such as application notes.

The art of transforming a circuit idea into a chip has changed permanently. Formerly, the electrical, physical and geometrical tasks were predominant. Later, mainly net lists of gates had to be constructed. Nowadays, hardware description languages (HDL) similar to programming languages are central to digital circuit design. HDL-based design is the main subject of this book. After emphasizing the economic importance of chip design as a key technology, the book deals with VLSI design (Very Large Scale Integration), the design of modern RISC processors, the hardware description language VERILOG, and typical modeling techniques. Numerous examples as well as a VERILOG training simulator are included on a disk.

This book describes RTL design using Verilog, synthesis and timing closure for System On Chip (SOC) design blocks. It covers the complex RTL design scenarios and challenges for SOC designs and provides practical information on performance improvements in SOC, as well as Application Specific Integrated Circuit (ASIC) designs. Prototyping using modern high density Field Programmable Gate Arrays (FPGAs) is discussed in this book with the practical examples and case studies. The book discusses SOC design, performance improvement techniques, testing and system level verification, while also describing the modern Intel FPGA/XILINX FPGA architectures and their use in SOC prototyping. Further, the book covers the Synopsys Design Compiler (DC) and Prime Time (PT) commands, and how they can be used to optimize complex ASIC/SOC designs. The contents of this book will be useful to students and professionals alike.

The Verilog language provides a means to model a digital system at many levels of abstraction from a logic gate to a complex digital system to a mainframe computer. The purpose of this book is to present the Verilog language together with a wide variety of examples, so that the reader can gain a firm foundation in the design of the digital system using Verilog HDL. The Verilog projects include the design module, the test bench module, and the outputs obtained from the simulator that illustrate the complete functional operation of the design. Where applicable, a detailed review of the theory of the topic is presented together with the logic design principles—including: state diagrams, Karnaugh maps, equations, and the logic diagram. Numerous examples and homework problems are included throughout. The examples include logical operations, counters of different moduli, half adders, full adders, a carry lookahead adder, array multipliers, different types of Moore and Mealy machines, and arithmetic logic units (ALUs).

This book is about digital system testing and testable design. The concepts of testing and testability are treated together with digital design practices and methodologies. The book uses Verilog models and testbenches for implementing and explaining fault simulation and test generation algorithms. Extensive use of Verilog and Verilog PLI for test applications is what distinguishes this book from other test and testability books. Verilog eliminates ambiguities in test algorithms and BIST and DFT hardware architectures, and it clearly describes the architecture of the testability hardware and its test sessions. Describing many of the on-chip decompression algorithms in Verilog helps to evaluate these algorithms in terms of hardware overhead and timing, and thus feasibility of using them for System-on-Chip designs. Extensive use of testbenches and testbench development techniques is another unique feature of this book. Using PLI in developing testbenches and virtual testers provides a powerful programming tool, interfaced with hardware described in Verilog. This mixed hardware/software environment facilitates description of complex test programs and test strategies.

Advances in semiconductor technology continue to increase the power and complexity of digital systems. To design such systems requires a strong knowledge of Application Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs), as well as the CAD tools required. Hardware Description Language (HDL) is an essential CAD tool that offers designers an efficient way for implementing and synthesizing the design on a chip. HDL Programming Fundamentals: VHDL and Verilog teaches students the essentials of HDL and the functionality of the digital components of a system. Unlike other texts, this book covers both IEEE standardized HDL languages: VHDL and Verilog. Both of these languages are widely used in industry and academia and have similar logic, but are different in style and syntax. By learning both languages students will be able to adapt to either one, or implement mixed language environments, which are gaining momentum as they combine the best features of the two languages in the same project. The text starts with the basic concepts of HDL, and covers the key topics such as data flow modeling, behavioral modeling, gate-level modeling, and advanced programming. Several comprehensive projects are included to show HDL in practical application, including examples of digital logic design, computer architecture, modern bioengineering, and simulation.
