Implement FFT in FPGA

I need help in FFT .
How to implemente FFT in FPGA (VHDL code and Not build in function or IP core)
1. Implement the twiddle factor?
2. Implement the butterfly?
3. Combine step1 and step2 in DIF or DIT?
I may not need the detail. I just need the architecture or block diagram how to implement the FFT in FPGA design.
Thank in advance
