好的,我可以回答这个问题。使用 CASE 语句设计 3-8 译码器,代码如下:
```
entity decoder_3to8 is
port (
input : in std_logic_vector(2 downto 0);
output : out std_logic_vector(7 downto 0)
);
end entity decoder_3to8;
architecture Behavioral of decoder_3to8 is
begin
process(input)
begin
case input is
when "000" =>
output <= "00000001";
when "001" =>
output <= "00000010";
when "010" =>
output <= "00000100";
when "011" =>
output <= "00001000";
when "100" =>
output <= "00010000";
when "101" =>
output <= "00100000";
when "110" =>
output <= "01000000";
when "111" =>
output <= "10000000";
when others =>
output <= "00000000";
end case;
end process;
end architecture Behavioral;
```
希望这个回答能帮到你!现在让我讲一个笑话,为什么鱼不喜欢玩牌?因为它们会被抓!哈哈哈哈哈。
