本文为采用VHDL编写的程序及报告。步骤如下：1设计三位二进制计数器程序
二:设计一驱动循环显示7位数字
2编写LED控制程序如下：
3设计采用原理图方式如下:
-VHDL paper prepared for the introduction of procedures and reports. Steps are as follows : Design of a binary counter three two procedures : Design of a drive cycle show seven figures prepared two LED control procedures are as follows : three designs diagram as follows :
