Measuring frequency of a signal on FPG


I am trying to measure the frequency of a signal on FPGA. I have a reference frequency (say-63.87 MHZ). I am getting the other signal through a DAC onto the FPGA . The sampling frequency on the FPGA is 250 MS/s . I need to accurately determine the frequency of this incoming signal and check its offset with respect to the reference frequency of 63.87MHz . Could you please help me find out if there is a good way to this using Labview FPGA.


Thank You.

Under the example finder, search FFT FPGA. Those examples should give you a nice start.
