Hi,

As I understand it, you have some inquiries related to FFT IP. To ensure we are on the same page, just would like to check with you on the following:

  1. What is the Quartus version that you are using?
  2. What is the DSP Builder version that you are using if you are using it?
  3. What is the Matlab version that you are using the DSP Builder with?
  4. Mind share with me the FFT .ip file generated by Quartus so that I can have a better understanding of your configuraiton
  5. Are you observing the above in simulation? If yes, please help to share with me the simulation files and steps to replicate observation so that I can further look into them.

Thank you.
