本文主要介绍以EP1C3/EP1C6芯片进行十字路口的交通控制灯的设计，该系统可控制2个方向的红、黄、绿三盏灯,让其按特定的规律进行变化。用EP1C3/EP1C6作为交通控制灯的主控芯片，采用VHDL语言编写控制程序，利用MAX+PlusⅡ对设计结果进行仿真，发现系统工作性能良好。据此设计而成的硬件电路,也实现了控制要求。该设计展示了VHDL语言的强大功能和优秀特性。-This paper introduces the crossroads EP1C3/EP1C6 chip design of traffic control lights, the system can control the direction of two red, yellow, green, three lights, let the law be changed according to the specific. As a traffic control light with EP1C3/EP1C6 master chip, using VHDL language control program, using MAX+ Plus Ⅱ design simulation results and found that system works good performance. Accordingly designed with the hardware circuit, also achieved control requirements. The design shows the power of VHDL language and excellent features.
