FIR IP configured for Interpolation

Why does my Altera FIR IP, configured for interpolation by 80, produce the expected outputs when I provide 3 input samples, but fail to produce the expected behavior when I provide 10 input samples? ...

I am using a Cyclone V device with Quartus Prime Lite 25.1 Edition.

Here I have attached the relevant top module and testbench code.

Any guidance would be greatly appreciated.

    Hi,

     

    Thanks for sharing the files. Please allow me some time to look into it and perform replication on my side. Please ping me if you do not hear back from me by early next week. Thank you.

    Hi,

     

    As I tried to replicate your simulation, I noticed that I would need a few other settings of your FIR II IP ie Coefficient Settings, Coefficients, Input/Output Options, Implementation Options and Reconfigurability. You may share with me the IP megawizard files. Thank you.
