Trying to test Filter using NCO Megafunction and Signal Tap Analyzer?

I've built a low-pass filter using Fdatool in matlab and used HDL coder in matlab to get a vhdl to simulate on hardware. i'm trying to use the NCO megafunction to generate a signal to be filtered in ...

Let me put it this way. You want to filter your input signal, then what determines sample rate is the sample rate when that signal was or is converted in an ADC(originally, assuming no further up or down sampling is done) or it could be your signal is generated digitally (rather than ADC) i.e. playing an LUT in which case the sampling frequency is the clock frequency that reads LUT.
