How to switch to visualize the output of FFT HDL Optimized in the frequency domain ?

So i just implemented the FFT HDL Optimized and a peak finder with index in Simulink in order to generate HDL code.
When i simulated the model in Vivado, the peaks were detected and it went great, but the indices of the peaks were obviously not in Hz (not in the frequency domain). How do i transform the indices of the peaks to the frequency domain ? or how do i view it in the frequency domain ?

If you did this in Simulink, you can send the output of the Simulink subsystem to the Spectrum Analyzer and do the analysis there.
Otherwise, you can capture the output from Vivado and then process it in MATLAB (again, using the Spectrum Analyzer).
