(完整word版)流水灯实验报告

1、FPG隔水灯实验报告实验目的熟练该软件的操作的同时，学会用VHD用言来编程流水灯的制作实验步骤步骤一）初步设定16位流水灯的流程图二）打开quartus软件，建立一个新工程，命名为liushuideng ，在义件处新建一个VHDLFile，编写程序。三）打开仿真-L具，设置仿具模式为Funnctional ,用自动的模式，然后执行仿真。四）进行编译运行结果，分析结果1、VHDLM程序：library ieee;use ieee.std_logic_1164.ALL;use ieee.std_logic_arith.ALL;use ieee.std_logic_unsigned.ALL;enti
