通过本扩展你可以直接把PCB文件推送给开源自动布线工具Freerouting，并且不需要手动运行Freerouting，并操作导入导出自动布线文件，实现一键自动布线，为PCB自动布线提供新的选择。
With this extension, you can directly push PCB files to the open-source auto-routing tool FreeRouting without manually running FreeRouting or handling import/export of routing files, enabling one-click auto-routing and providing a new option for PCB automatic routing.
