This book by more than 100 module instance, explain in detail the Verilog HDL programming language, the book is divided into 13 chapters, covering basic concepts VerilogHDL languages, modeling, synchronous design, asynchronous design, functional verification, etc. Examples include a variety of additions device/counters, multipliers/dividers, encoders/decoders, state machines, SPIMaster Controller, I2C Master controller, CAN ProtocolController, Memory modules, JPEG image compression module, encryption module, ATA controller, 8-bit RISC-CPU etc. and the various instances of the corresponding module Testbench, The examples are highly practical and representation, each instance of it all gives the introduction, functional analysis, program code and the results demonstrate)

一个具有“百分秒，秒，分”计时功能的数字跑表，可以实现一个小时以内的精确至百分之一秒的计时。 数字跑表的显示读者可以通过编写数码管显示程序来实现，本训练只给出数字跑表的实现过程。 读者还可以通过增加小时的计时功能，实现完整的跑表功能。-A " percentage of seconds, seconds, minutes," digital stopwatch timer can be achieved within an hour of precision to the hundredth of a second time. Digital stopwatch readers can display the digital display through the preparation of procedures to achieve, given the training is only the realization of the process of digital stopwatch. Readers can also function to increase hours of time to achieve full stopwatch function.
