流水灯运行程序报错，用的是quartus软件调试

你好，用你的电脑NIC地址再拷贝进去就好了，把license。DAT里面的HOSTID改为现在的即可，碰好ID可以在软件上面工具栏的“TOOLs”license setup里面有NICID复制激或过去！我的就是这样改明吵伍的，问题是一样的，不知道效果一样不！

貌似改成两个[3..0]的脚吧？用VHDL语言编写程序，让他自己去生成一个三八译码器就好了嘛，程序如下：

library IEEE

use IEEE.Std_Logic_1164.ALL

entity decoder IS

port (in1 : in Std_Logic_Vector(2 downto 0)

out1,out2 : out Std_Logic_Vector(3 downto 0))

end decoder

architecture decoder38 of decoder is

begin

decoder:process(in1)

begin

case in1 is

when"000"=>out1<="00000001"

when"001"=>out1<="00000010"

when"010"=>out1<="00000100"

when"011"=>out1<="00001000"

when"100"=>out2<="00010000"

when"101"=>out2<禅岁="00100000"

when"110"桥袭弯=>out2<="01000000"

when"111"=>out2<="10000000"

when others=>null

end case

end process decoder

end decoder38

自己去实现敏闷吧，哈哈……
