利用数字电路知识，进行二十四小时计时，并有闹钟与蜂鸣器功能...

用VHDL写的运动计时表程序，用Modelsim仿真已经通过，帖出来与大家分享。-write VHDL campaign time table program, Modelsim simulation has been passed, Tie up share with you.

spwm dcac逆变 fpga与单片机一起作用(sdad)

自己写的pwm占空比采集与输出 但是没有计算占空比，如果又需要可以自己修改计算并显示占空比，该程序已经测试过了，可以使用，拿出来供大家分享，新手写的如有不足请大牛带飞。

通过LED闪烁控制器的代码，使用Vivado工具配置定义一个IP核，在用户工程中可随意添加这个IP核作为设计的一部分，如同Vivado自带的IP核一样方便调用和集成。(Through the code of the LED scintillation controller, the Vivado tool is configured to define a IP core, and the IP kernel can be added as part of the design at random in user engineering. It is as convenient to call and integrate as the IP kernel with Vivado.)

拿verilog编写的som(自适应神经网络算法)，用于障碍物检测，基于FPGA可综合实验，已经在altera的cylcone上实现(Canal verilog prepared som (adaptive neural network algorithm) for obstacle detection. Based on FPGA synthesis experiments, in altera achieve the cylcone)

Verilog投币式手机充电仪 清华大学数字电子技术基础课程EDA大作业。刚上电数码管全灭，按开始键后，数码管显示全为0。输入一定数额，数码管显示该数额的两倍对应的时间，按确认后开始倒计时。输入数额最多为20。若10秒没有按键，数码管全灭。(Verilog coin operated cell phone charger EDA major homework of digital electronic technology foundation course, Tsinghua University. Just put on the digital tube completely extinguished, press the start button, the digital tube display is 0. Enter a certain amount, the digital tube shows the amount of double the corresponding time, according to the confirmation began countdown. The maximum amount of input is 20. If there is no button in 10 seconds, the digital tube will die out.)
