modelsim 进行仿真时总是显示Error loading design

Question

compile all 的时候没有任何问题，代码检查过也没有问题，但是一点开始仿真就提示
vsim -gui work.mux_test -novopt

vsim -gui work.mux_test -novopt

** Error (suppressible): (vsim-12110) All optimizations are disabled because the -novopt option is in effect. This will cause your simulation to run very slowly. If you are using this switch to preserve visibility for Debug or PLI features, please see the User's Manual section on Preserving Object Visibility with vopt. -novopt option is now deprecated and will be removed in future releases.
