How to implement and simulate FFT IP with SimuLink on FPGA (Cyclone V GX starter kit) error vsim-3033

Hi, thank you for your answer.

I really want to generate a testbench to implement the inputs to the circuit myself because later I am going to add more blocks to the schematic.

I get the vsim 3033 error in modelsim when I generate testbench in the ip editor and do an rtl simulation with it.

On the other hand, I have tried what you told me but I do not know how to handle modelsim very well and this is what I have obtained by following the steps.

Thank you for your time,

Best regards.
