Problem in adding custom component

Hi all,

I've developed a module used to do RSA algoritham. The module port is as follows:

entity RSA_CoProcessor is

port(

Reset: in std_logic;

CLK: in std_logic;

Chipselect: in std_logic;

Address: in std_logic_vector(3 downto 0);

WriteData: in std_logic_vector(31 downto 0);

ReadData: out std_logic_vector(31 downto 0)

);

end RSA_CoProcessor;

To do the interface between this module with PC, I plan to add this module to niosII in order to control the data transmission between PC and the RSA module.

Now i m at the sopc stage. i m facing a problem in connecting the above ports to the nios processor. Can someone guide me on this?

Lastly, i m new in using sopc builder.

Thanks,

Ren Yi
