Hi,

thank you for the replay. I have tried with the Native Floating-Point DSP IP and it seems that the issue I was attributing to rounding errors has been resolved by using that IP, though I should run more thorough tests—even so, the differences are indeed quite significant. 

In any case, in my opinion, it would be advisable to have clearer documentation regarding each of the IPs available in Quartus.

Hi Frank,

 

Thank you for the update. I’m glad to hear that the Native Floating‑Point DSP IP has resolved the rounding issue. From my understanding, the Native DSP IP allows users to access the DSP block directly, without relying on inference.

 

Please let me know if you have any questions or concerns. Thank you.
