I am woring on Fast Fourier Transform algorithm and my C code has recursive function.
When I am trying to do synthesize its showing error of not supported recursive functions. Can I change it to while loop and stack. If I change my code then is synthesize works?

There is no such thing as recursive hardware.

Need to unroll the recursion. You don't have to implement a stack. There are several non-recursive FFT's available just google search: "fft c code non recursive"
