这是利用 Verilog HDL 语言在 Quartus Prime 软件上进行 FPGA 编程实现的几个程序，所有程序都可以在DE10 Standard开发板上顺利运行。三个程序实现的功能分别是：简易的键盘电子琴，简易的字符输入编辑屏幕输出系统，打字小游戏。每个项目工程源文件在相应的文件夹中，可以直接在Quartus Prime 平台上打开。

These are several FPGA programs programmed in Verilog HDL, enabling by Quartus Prime platform. All these programs can be successfully run on DE10 Standard demo board. The functions of these programs are: a simple electronic keyboard, a simple character inputing and editing system which can show the outcome on screen, a typing game. Each project's source coding file are in corresponding folder, which can be directly opened on Quartus Prime platform.
