Indeed, it is. I found this line:

set_global_assignment -name SDC_FILE [file join $::quartus(qip_path) B_example_top.sdc ]

Up to now, I was not aware that the .qip was user readable (in fact it's looking very similar as the .qsf file to me). So taking out the unwanted part hopefullya solves the issue. Do you know any limitations editing the .qip file (as they don't really mention this in manuals...)?

However the including of the "example_top" files must be a new "feature" (wasn't like this in Quartus II 9.0). In my opinion not very useful, as most people won't use "example top" in their "real" designs...

Anyway, thanks for the hint!
