Fixed point FFT output scaling issue

Hi,

I'm trying to implement a fixed point FFT processor using the intel FFT core. I simulated the design and it gave a scaled result. But how can I check the exact value that the processor used to scale?

 

Best wishes

Hi,

 

As I understand it, you have some inquiries related to the FFT. Would you mind to share with me further on the following:

 

  1. What is the Quartus version that you are using?
  2. What is the device that you are using?
  3. Mind share with me the your FFT .ip file so that I can have better understanding of your configuration?

Thank you.
