用PROTEL软件设计的FPGA最小系统板。FPGA的型号为EP1C3-144，需要制作最小系统板的可以参考一下。-PROTEL software design of the FPGA with the minimum system board. FPGA-model EP1C3-144, need to make the minimum system board that can be reference.

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
