Hi !
I have designed a filter in MATLAB with the fixed coefficients, and simulink is pass ,meet the requirements。So export the fixed coefficients to fir compiler v9.1 , set the Structure Type to Fully Parallel Filter。 When run in FPGA,the results of filter output is different from matlab , Error will increase when the data is large. thanks for replyLink Copied

Hello,
What are your filter settings? (coefficient bitwidth, scaling, output bitwidth etc.) Grt, Olaf- Mark as New

Hi, Olaf
The coefficient has been exported fir compiler v9.1 , So I set scaling options for "none" ,the same as MATLab。 output bitwidth is “full solution”。- Mark as New

Did you check the errata for the fir compiler? perhaps this is a known issue and already has a workaround..
