Frank Vahid is a professor of computer science and engineering at the University of California, Riverside. He is also the author of Digital Design with RTL Design, VHDL, and Verilog, a popular textbook that covers the fundamentals and implementation of digital design using modern techniques and tools. The book is suitable for undergraduate students, graduate students, engineers, hobbyists, and anyone who wants to learn more about digital design.


The book has many features and benefits that make it a valuable resource for learning digital design. Some of them are:



  • It emphasizes register-transfer level (RTL) design, which is central to the million-gate integrated circuit era.



  • It teaches modern "Capture/Convert" top-down design methodology for combinational, sequential, and RTL design.



  • It provides hundreds of examples to motivate and demonstrate concepts, over 600 figures to illustrate ideas, and exceptionally lucid text.



  • It covers hardware description languages (HDLs) in a separate chapter to clearly distinguish basic design concepts from present-day implementation mechanisms.



  • It includes VHDL, Verilog, and even SystemC to provide instructor flexibility while also showing essential HDL similarities.



  • It offers optional low-cost accompanying books for in-depth coverage of VHDL and Verilog.



  • It provides over 600 author-created PowerPoint slides as a serious and useful teaching aid.



  • It distinguishes between basic design and optimization, as well as tradeoffs.



  • It explains how FPGAs implement circuits as bitstreams.



Digital Design Fundamentals




The book starts with an introduction to digital design fundamentals. It covers the basic concepts of digital circuits and systems such as binary numbers, Boolean algebra, logic gates, truth tables, Karnaugh maps, etc. It also explains how to design combinational logic circuits such as decoders, encoders, multiplexers, demultiplexers, etc. using various methods such as gate-level minimization, algebraic manipulation, tabular methods, etc.


The book then moves on to sequential logic design. It introduces the concept of state machines and how they can be used to model sequential behavior. It also shows how to design sequential logic circuits such as flip-flops, latches, registers, counters, shift registers, etc. using different types of state diagrams such as Mealy, Moore, and HLSM. It also discusses how to optimize sequential logic circuits using state minimization, state encoding, state assignment, etc.


The book then progresses to register-transfer level (RTL) design. It defines RTL as a level of abstraction that captures the behavior of a digital system using registers and operations on those registers. It also describes the "Capture/Convert" process, which is a top-down design methodology that involves capturing the behavior of a system using RTL statements and then converting them to a lower-level implementation using HDLs or FPGAs. It also provides several examples of RTL design such as arithmetic circuits, controllers, datapaths, etc.


Digital Design Implementation




The book then covers digital design implementation using hardware description languages (HDLs) and field-programmable gate arrays (FPGAs). It explains what HDLs are and how they are used to describe the structure and behavior of digital circuits and systems. It also compares and contrasts the three main HDLs: VHDL, Verilog, and SystemC. It provides the syntax and examples of each HDL for various types of design such as structural, behavioral, dataflow, etc.


The book then introduces FPGA architecture and programming. It explains what FPGAs are and how they are composed of programmable logic blocks, interconnects, input/output blocks, memory blocks, etc. It also shows how FPGAs implement circuits as bitstreams that configure the logic elements and connections. It also provides examples of FPGA programming using VHDL and Verilog.


Digital Design Applications




The book then explores some of the applications of digital design in various domains such as microprocessors, arithmetic circuits, memory components, and digital filters. It explains how microprocessors are designed using RTL design and HDLs. It also describes the basic components and architecture of a microprocessor such as instruction set, datapath, control unit, registers, ALU, etc. It also provides examples of microprocessor design such as MIPS and ARM.


The book then discusses arithmetic circuits and algorithms. It shows how to design basic arithmetic operations such as addition, subtraction, multiplication, division, etc. using combinational and sequential logic circuits. It also explains how to optimize arithmetic circuits using techniques such as carry-lookahead adders, Booth's algorithm, Wallace tree multiplier, etc. It also provides examples of arithmetic algorithms such as fast Fourier transform (FFT), discrete cosine transform (DCT), etc.


The book then covers memory components and systems. It explains how to design memory elements such as flip-flops, latches, registers, etc. using sequential logic circuits. It also shows how to design memory structures such as RAM, ROM, cache, etc. using combinational logic circuits. It also discusses how to optimize memory systems using techniques such as memory hierarchy, mapping methods, replacement policies, etc.


The book then concludes with digital filters and signal processing. It introduces the concept of digital filters and how they can be used to process signals such as audio, video, images, etc. It also explains how to design digital filters using techniques such as finite impulse response (FIR), infinite impulse response (IIR), convolution, frequency response, etc. It also provides examples of digital filter applications such as low-pass filter, high-pass filter, band-pass filter, etc.


Conclusion




In conclusion, Digital Design with RTL Design VHDL and Verilog by Frank Vahid is an excellent book that covers the fundamentals and implementation of digital design using modern techniques and tools. The book is suitable for anyone who wants to learn more about digital design and its applications in various domains.

Here are some FAQs about the book and digital design:



  • Q: What are the prerequisites for reading this book?



  • A: You should have some basic knowledge of mathematics (such as algebra and calculus), physics (such as electricity and magnetism), and programming (such as C or Java).



  • Q: What are the differences between VHDL, Verilog, and SystemC?



  • A: VHDL stands for VHSIC Hardware Description Language. Verilog stands for Verification Logic. SystemC stands for System C++. They are all HDLs that can be used to describe digital circuits and systems at different levels of abstraction. VHDL is more verbose and structured than Verilog. Verilog is more concise and flexible than VHDL. SystemC is an extension of C++ that supports concurrent and hardware-oriented features.



  • Q: What are the advantages and disadvantages of FPGA programming?



  • A: FPGA programming is the process of configuring an FPGA device to implement a digital circuit or system. The advantages of FPGA programming are that it is fast, flexible, and scalable. You can quickly test and modify your design without going through the fabrication process. You can also customize your design to fit your specific needs and constraints. The disadvantages of FPGA programming are that it is expensive, complex, and power-hungry. You need to buy an FPGA device and a programming board, which can cost a lot of money. You also need to learn how to use the FPGA software tools, which can be complicated and time-consuming. You also need to consider the power consumption and heat dissipation of your FPGA device, which can affect its performance and reliability.



  • Q: What are some of the applications of digital design in the real world?
