duplicate a component

can I do something like this ?

many thanks!!!!

1. ARCHITECTURE

-------------------------------

COMPONENT pulser

-------------------------------

PORT

(

hifu_hv_pw :in std_logic_vector ( 7 downto 0 ) --0->15 hifu_pw

);

END COMPONENT;

2.ARCHITECTURE

type m0 is array (1 downto 0) of std_logic_vector(7 downto 0);

signal array_pw: m0 ;

3. BEGIN

hifu_hv_pw0<="01010101";

hifu_hv_pw1<="11111111";

array_pw <= hifu_hv_pw1 & hifu_hv_pw0 ;

4. PORT MAP

puls : for n in 1 downto 0 generate

pulser_port:pulser

port map

(

hifu_hv_pw => array_pw(n)

);

end generate puls;
