摘 要
交通灯控制器在城市交通监管中起着极其重要的作用。传统的交通灯控制器基本是通过单片机或者PLC实现。本文介绍基于FPGA技术和Quartus II开发平台实现十字路口交通灯控制器的的一种方案。利用VHDL硬件描述语言描述各模块程序，并在Quartus II环境下进行编译、仿真，生成顶层文件后下载在FPGA器件FLEX EPF10K10LC84上进行验证。验证结果表明，设计基本实现了交通灯控制器所要求的控制过程，包括倒计时时间显示功能、特殊状态控制功能和主、支干道的红、黄、绿灯交替显示功能，表明本文所述的的设计方案正确。
本文结合交通灯控制器的设计过程，简单介绍了硬件描述语言VHDL的结构模型和设计流程、 VHDL设计的优点及该语言在数字系统设计中的美好前景和重要地位。

Abstract
Traffic light controller is playing an important role in the municipal transportation supervision. The traditional traffic light controller majority realizes through the monolithic integrated circuit or PLC. This article introduced one kind of plan which is based on FPGA and Quartus II programming environment to realize the crossroad street intersection traffic light controller. The programming language is VHDL hardware description language, which is widespread at present. The procedures of each model have been carried on the translation and simulation under the environment of Quartus II of Altera Corporation, and downloaded on FPGA component FLEX EPF10K10LC84. The traffic light controller has realized the controlling process basically, including the countdown time demonstrating the function, the special state control function and main, a yang or male principle red, yellow, and green light demonstrating the function alternately, the confirmation result indicates that the system's design proposal is accurate.
This article unified the traffic light controller's design process and introduced the structural model and the design cycle of hardware description language VHDL simply. It showed us the merit of the use of the VHDL and the magnificent prospect and the important position of this language in the number system design.
