What do you mean by "external" component?

If your peripheral has an Avalon interface, then you simply create a SOPC component and you can hook it up to your NIOS etc. in SOPC.

The component may have "conduit" signals which interface to the outside world.

If you really need/want the component to be instantiated outside SOPC, then you're in effect hooking it up via/to an Avalon bridge.
