Problem with FIR II filter

I want to configure FIR II filter to convert 15 MSPS data to 15.36 MSPS data. In order to do this Interpolation factor should be 128 and decimation factor should be 125. I have described the same below diagram:

But when I try to configure FIR II IP I am getting below errors:

Error: gj: Cannot have fewer taps than the amount of interpolation
Error: gj: Output Fractional Full Bit Width should greater than Output Fractional bit width
Error: gj: Output Bit Width should be greater than 1
Error: gj: Port ast_sink_data is not fully defined after elaboration
Info: gj: PhysChanIn -1, PhysChanOut -1, ChansPerPhyIn -1, ChansPerPhyOut -1, OutputFullBitWidth -1, Bankcount 1, CoefBitWidth 8

 

Filter specification settings:

Coefficient settings is as below:

input output parameters are as below

 Please guide me to resolve this error to get the IP working.

Hi,


Sorry for the delay. By merely looking at the error message, it seems like the specific configuration that you are selecting are not a valid combination by the IP. Please allow me some time to further look into this and get back to you.
