interface code

Hello Sir,

a,b,c ,p,q,r, and s are floating.

the code i wrote was -

library ieee;

use ieee.std_logic_1164.all;

entity cir2 is

port(x1,y1,z1:in std_logic;

x2,y2,z2:out std_logic);

end cir2;

architecture struct of cir2 is

begin

cir1_inst : entity work.cir1

port map (x1,y1,z1); --- sir pls note this step. Where can i map a,b and c ?

cir3_inst : entity work.cir3

port map (x2,y2,z2); -- Likewise here where can I map x1,y1 and z1?

Sorry to trouble u sir.

Regards,

Vinod.
