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

Start time: 08:21:06 on Mar 05,2020

** 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.

同样问题已解决，modelsim安装后破解的最后一步：“修改安装目录下Modelsim.ini文件的只读属性，然后修改其中的voptflow=0！”引起的。把voptflow改回默认的1就行了。‘工程仿真\simulation\modelsim\’路径下也有一个modelsim.ini文件，和安装目录下的那个配置一致。
