仿真时，每次选择不带优化的仿真就会出现以下报错，请问要怎么解决呢。网上有问这个问题的，但都没有看到相关解答。

# ** 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.
