说明：  经典的雷鸟车灯控制电路设计，各大高校实验必做题目(Thunderbird classic light control circuit design, major colleges and universities must do experimental subjects)

说明：  实现主干道交通灯显示，以状态机程序实现，并用数码管进行红绿灯倒计时的显示，内置计数模块，交通灯控制模块，数码管显示模块，并对各模块用电路图的方式进行连接。对于学习VHDL语言有所帮助。(The main road traffic light display is realized by the state machine program, and the digital tube is used to display the traffic light countdown. The counting module, the traffic light control module and the digital tube display module are built in, and each module is connected by the circuit diagram. It is helpful for learning VHDL.)

Rst是低电平有效的系统复位信号，Clk是时钟信号。AB[5：0]是地址信号，DB[7：0]是数据信号，wr是低电平有效的写信号。start是启动信号。 模块中有一个64x8的双端口的存储器。系统复位结束后，可以通过AB、DB和wr信号向同步存储器写入数据。当写入64个数据后，给出一个Clk周期宽度的脉冲信号start，则系统从存储器0地址处开始读出数据，读出的8位数据从低位开始以3位为一组，每个时钟周期输出一组，即第一个时钟周期输出[2：0]位，第二个时钟周期输出[5：3]位，第三个周期输出1地址的[0]位和0地址的[7：6]位，直至将存储器中64x8数据全部输出。若最后一组不足三位，则高位补0。 (Rst is an active-low system reset signal, Clk is a clock signal. AB [5: 0] is the address signal, DB [7: 0] is the data signal, wr write signal is active low. start is the start signal. Module in a dual port memory of 64x8. After the reset, you can write data to the synchronous memory by AB, DB and wr signals. When data is written to 64, given the width of a pulse signal Clk cycle start, the system begins to read the memory address 0, 8 data read out a low starting with three as a group, each clock outputs a set period, which is the first clock cycle of the output [2: 0] bits, the second clock cycle output [5: 3] position, the third cycle of the output of an address [0] and 0 address [7 : 6] bit, until all the data in memory 64x8 output. If the last group of less than three, the high 0s.)
