I would bet on 'configurations'. They are a rather obscure (why?) vhdl construct. It seems most RTL engineers just make entities of only one implementation, and don't use the configuration language feature to select different implementations, e.g. Spartan 6, inferred or simulation. A lot of proprietary tools have problems with this, at least in older revisions.
The soc infrastructure and decoder selection uses this construct.
