给大家上传一本非常好的关于verilog-hdl的电子书，实用，易懂，易学。此为第七章(Give us a very good upload on verilog-hdl of e-books, practical, easy-to-understand, easy to learn. This is the Chapter VII)

本文分析了当前国内外出租车计费系统的基本组成和工作原理及主要的两种设计方式:基于单片机的设计方式和基于FPGA的设计方式；并对这两种实现方式的优点和缺点进行分析，比较后确定本系统的方案：基于FPGA的出租车计费系统的设计。(This paper analyzes the current taxi charging system at home and abroad, working principle and basic components of two major design approach: the design methods based on single chip FPGA-based design approach and the two implementations to analyze the strengths and weaknesses, After comparing the program to determine the system: FPGA-based taxi billing system.)

说明：  fpga程序，产生1pps脉冲信号，使用的verilog语言。(FPGA program generates 1 PPS pulse signal, using Verilog language.)
