Error evaluating 'StopFcn' callback of block_diagram 'spectral_purity'. Callback string is 'doFFTplot(fs, fs_over_4, 'NCO output', 1, 2, 'hann'); set(2,'Name','FFT Plot of NCO Output','NumberTitle','off'); setStandardFigSize(2); '

Caused by:

Undefined function 'doFFTplot' for input arguments of type 'double'.

I couldn't find any reference to doFFTplot in Matlab/Simulink documentation. Is this code that you wrote or obtained from another person?
