各位老师,您们好! 麻烦指点下程序包的编写问题,谢谢!! 顺便帮我看下这个程序有什么问题,编译时没法进行,谢谢!!!!
library ieee; use ieee.std_logic_1164.all;
package pac_devider is
component fredevider4 is port (clock:in std_logic; clkoutut std_logic ); end component fredevider4;
component fredevider10 is port (clock:in std_logic; clkoutut std_logic ); end component fredevider10;
component mux2 is port (clkA,clkB:in std_logic; clkoutut std_logic; sel:in std_logic ); end component mux2;
end pac_devider;
(注:因没涉及到子程序,所以没有包体)
