基于VHDL语言的数码管闪烁控制的实现

摘要

介绍了在MAX＋PLUSⅡ开发环境下,用VHDL语言设计一种用于控制8路数码管闪烁的电路。该电路具有4种花型,且可以变换速度。通过MAX＋PLUSⅡ软件进行波形仿真后,利用实验板提供的资源,下载到芯片中实现预定功能。%A design of the eighty LED digital display flicker circuit based on VHDL is introduced with the MAX＋PLUS II.The system can demonstrate four kinds of flowers cyclically with different speeds.After the simulation is correct with the MAX＋PLUS II software,the resources provided by experimental board is download to chip for achieving the function.
