Connecting BRAM block to Self designed BRAM controller

Hi all,

I am using XPS 8.2i and ISE 8.2i and a virtex-4 board.As a part of
assignment, I have to write a verilog/vhdl
code for a BRAM controller by which we can perform read/write
operation on a BRAM block.I have written a
desired verilog code for BRAM controller. Also I have added a Bram
block to my assembly from pool.But My
System assembly does not show any port in my BRAM controller to which
I can connect the BRAM block.

Any suggestions would be greatly appreciated

thanks
Rinky
