test2

代码说明：

说明：  试用Verilog HDL语言，设计十进制计数器，将计数过程用一个数码管进行显示（0～9）。要求首先使用Modelsim软件进行功能仿真，然后使用Quartus软件综合，并下载到开发板进行电路功能测试。(Using Verilog HDL language, a decimal counter is designed. The counting process is displayed by a digital tube (0 ~ 9). It is required to first use Modelsim software for functional simulation, then use quartus software for synthesis, and download to the development board for circuit functional test.)
