VHDL编写的交通灯程序，有倒计时功能，数字电路课程设计，内附状态图和dofile波形模拟！-VHDL prepared by the traffic lights procedures, the countdown function, digital circuit design courses, enclosing a state map and dofile waveform simulation!

应用８２５５芯片的交通灯程序，可以同过实验板上的按键来达到普通模式，紧急模式，和人工模式。内附设计报告-8255 chip application traffic lights procedures can experiment with the board over the keys to achieve the common mode emergency mode, and manual mode. Enclosing design report

交通灯控制器的程序,程序不是太复杂,我自己编的,没有错误-traffic light controller procedures that are not too complex, I developed, and no mistake

用VHDL实现交通灯的功能 很实用的 我认为比其他的的交通灯程序更好
