    Hi,


    Please see the technology Map viewer as well. It seems there is no issue with the IP or build or resource estimation.


    Can you please try with the simulation block by block and provide a sufficient input value to the filter, so that after multiplication with the coefficients it should not be very low value, at least you should get a signal in the +/-1 range. You definitely need to do scaling.


    Thank you

I guess that the problem can be seen in source code, e.g. incorrect scaling of coefficient multiply. Preferably trace signal path in simulation, see where it's cut.
