    IIR not working on system genrator

    Im trying to implement 2nd order IIR filter ( direct form 1) by xilinx block set in system generator but on output im getting noise.

    same filter i implemented in matlab simulink (without using xilinx block) it is working fine.
    I checked till feed forward path the output of matlab simulink and system generator both are same. i think that some problem in feed back path.


    Any idea whats going wrong? it will be great help

    thanks in advance

    Which version are you using?. I have used some FIR from xilinx sys gen. However did you meet proper input and output sample rate?.
