主文件.cpp的名字为top module的名字加前缀V，如果没top module则为文件名加前缀V

  • verilator/src/V3EmitCMain.cpp
    • filename = v3Global.opt.makeDir() + "/" + topClassName() + "__main.cpp";
      • verilator/src/V3EmitCBase.h: v3Global.opt.prefix();
        • src/V3Options.h: string prefix() const VL_MT_SAFE { return m_prefix; }
          • src/V3Options.cpp 
              // Default prefix to the filename
  if (prefix() == "" && topModule() != "")
      m_prefix = string{"V"} + AstNode::encodeName(topModule());
  if (prefix() == "" && vFilesList.size() >= 1)
      m_prefix = string{"V"} + AstNode::encodeName(V3Os::filenameNonExt(*(vFilesList.begin())));

主文件.h的名字，同理

  • verilator/src/V3EmitCModel.cpp
    • filename = v3Global.opt.makeDir() + "/" + topClassName() + ".h";
