Module removal by compilation optimization

I want to synthesize soft CPU IP by itself and evaluate resources. I created a TOP wrapper to implement a CPU module. However, when I look at the compilation result, I can't find the CPU module I ...

CPU was released by the 3rd vendor.

I created a Top wrapper that outputs the IO of the CPU Top module to the FPGA pin.
