How does a fixture port affect an assembly file?

[junfanbl]

Hello, I have been trying to diagnose an issue I am having with an assembly file. It is suspected that the issue might have something to do with fixture ports. Do fixture ports create wave links? Or rather, does the UG/Routing application create wave links automatically? There is an issue with my assembly when I run code on it, where it returns an extra component when it shouldn't be. It seems like wave linking is the culprit, but there are no signs of wave linking in the part navigator. However, because the UG/Routing application was used to make these assemblies, I am told that the application might create wave links "behind the scenes". Either way we aren't sure, but I thought I'd ask to confirm.
