说明：  至简设计法--VGA显示动画 工程说明 本工程VGA显示要求：复位后，屏幕中央显示直径为10的蓝色圆点；按下按键0，圆点图像逐渐变大，直至直径变为400；再按一下按键0，圆点逐渐变小，直到直径为10。此过程要有明显的动画效果。 案例补充说明 本设计的VGA图像动态显示是基于FPGA实现的，采用了Verilog HDL语言编写，再加上有明德扬的至简设计法作为技术支撑，可使程序代码简洁且执行效率高。
(Engineering description The engineering requirements: reset, VGA display screen display central diameter 10 blue dots; press the button 0, dot image gradually become larger, until the diameter is 400; then click the button 0, dots became smaller, until the diameter is 10. This process should have an obvious animation effect. Case Supplement The design of the VGA dynamic image display is realized based on FPGA, using Verilog HDL language, plus Ming Stankovic to simple design method as technical support, can make the code simple and high efficiency.)
