How to design a double precision floating point fft? And how to simulata this project in modelsim?

I have generated a Unified FFT ip in quartus prime pro21.1. Then the input terminal is connected to the ROM module. I wonder if that will work well. how do I use Modelsim to simulate it. (The Version of Modelsim is ModelsimSE 10.4)

    This is my .do file, and the Error reported in ModelSim is

    # ** Error: D:/hxm/intelfpga_pro/21.1/quartus/eda/sim_lib/cyclone10gx_atoms.vhd(1358): Can't recompile existing protected design unit "cyclone10gx_mux41" as unprotected.

    What can I do to avoid this and simulate the correct result?
