Description: 随着EDA技术的发展及大规模可编程逻辑器件CPLD／FPGA的出现，电子系统的设计技术和工具发生了巨大的变化，通过EDA技术对CPLD／FPGA编程开发产品，不仅成本低、周期短、可靠性高，而且可随时在系统中修改其逻辑功能。本文利用VHDL语言设计出租车计费系统，使其实现汽车启动、停止、暂停时计费以及预置等功能，通过设置计数电路进行路费及路程的计数，通过设计数据转换电路将路费及路程的十进制数分离成四位十进制数表示，通过设计快速扫描电路显示车费及路费，突出了其作为硬件描述语言的良好的可读性的优点。通过MAX+PLUSⅡ软件编写、调试和优化源程序，下载到特定芯片（MAX系列的EPM 7128SLC8415）后，即可应用于实际的出租车计费系统中。-ith the development of EDA technologies and large-scale programmable logic device CPLD/FPGA emergence of electronic systems design techniques and tools has undergone tremendous changes, through the EDA technology CPLD/FPGA programming product development, not only low-cost, short lead time, high reliability, but also may at any time in the system to modify its logic function. In this paper, VHDL language design taxi billing system to achieve the car to start, stop, pause, time billing and preset functions, by setting the tolls and the distance counting circuit count, through the design of data conversion circuits and the journey will be toll separated into four decimal decimal number, said a quick scan through the design of the circuit shows fares and tolls, highlighting its position as a hardware description language, the advantages of good readability. Through the MAX+ PLUS Ⅱ software development, debugging and optimizing the source code, download to a specific chip (MAX series of EP
