SOPC builder and SDR SDRAM Controller

How can I include the SOPC builder SDRAM controller in my top level design. I'm so far that I generated the SDRAM controller and connected the Avalon-MM pipeline bridge. I connected the SDRAM controller with the master port. I thought thats should be enough and I can generate a component which I can include in my top level design and connect the slave port with my design components.

I want just use the SOPC SDRAM controller and I don't want to built up my hole design on SOPC.

Thanks!
