好像不是这样。看vlog中关于他的说明:“Searches the specified resource library for precompiled modules. Optional.This argument can be used in tandem with -fast (see above) when you need to optimize pre-compiled modules for which you don't have source code. The library search options you specify here must also be specified when you run the vsim command . ”。
从说明看,它也是搜索已经编译好的module。
