It is a property of the component .tcl file. Here is the .tcl API: http://www.altera.com/literature/hb/qts/qts_qii54022.pdf

I write a lot of components and I always start by using component editor and then make manual changes to the .tcl file after if needed. This saves me a few hundred lines of .tcl coding.

Before coding up the .tcl file I would check to make sure your IP has Avalon complaint interfaces. You can find the various interfaces and signals that belong to each in the Avalon spec: http://www.altera.com/literature/manual/mnl_avalon_spec.pdf
