If the frequency response is O.K. for your application, no problem to use it. So you basically have to cut the extra LS bits from the 20 bit output. There seem to be some some confusion with the sampling rate of the simulation file, but you should be able to clarify the point when including the filter in a real design.

I remember, that some FIR compiler users previously had problems with the usage of source/sink handshake signals. I hope, that the meaning of these signals is said clear enough in the FIR users guide.
