Hi,


Sorry for the typo. I am actually referring to "hardware observation is matching the FFT simulation". Sorry for missing out the "simulation" which cause confusion.


To ease the debugging, you can try to use Matlab's simulation result as golden reference. Then, feed the same set of data to the FFT simulation. Generally the FFT would have almost similar behavior as the Matlab golden FFT.


Please let me know if there is any concern. Thank you
