Using FFT Megacore function in QuartusII project itself

Hi all,

I just want to know if it is possible to use the VHDL code generated in MegaWizard Plug-in manager's FFT Megacore function in a QuartusII Project and program an altera DE2-115 board.

Say I have two signal to be compared, one of which is in frequency domain and the other is in time domain.
I need to do an FFT to this time domain signal.
In this case is it possible to use the FFT Megacore function generated VHDL code and program the Altera board.

Thanks,
Nadeem
