移植了一份程序，之前工程是Cyclone II 后来换成 Cyclone IV E EP4CE10E22C8
用到的资源：pll，sdram，vga
移植办法：
1、更改工程配置，重新选择ic
2、重新分配管脚
3、编译下载至目标板
4、运行ok
以下是这个项目的一些重要信息
再看看警告
如此蛋疼的警告，虽然28个但是确实不影响使用
再看看运行结果，确实不错，没有问题，唯一的问题，就是需要多次复位才能正常
再看看这一堆蛋疼的垃圾文件，都是无用，看着让人心烦。果断删除
删除后结果
重新编译：发现有变化
1、资源消耗发生变化。
2、警告数量发生变化
下载运行，已经全然无反应了，无法工作，继续研究！！
垃圾无用的包含文件，果断删除
重新编译！！
警告数减少，依然无法正常工作！！
看看是神马警告
