I need to shift a signal by 30 degree in simulink and I found that it can be done by Fast Fourier transform. I am not able to perform this solution.

Hi Gaurav,
The simplest method is to use the Phase Shift Block and specify the Phase Shift as '30' with the unit being 'deg'.
If it is required to use FFT/IFFT manually, the following link provides a complete explanation to achieve this:
For Simulink, you may create a MATLAB function block or create a sub-system for this approach.
