Automatic routing When the routing quality meets the design requirements, the automatic routing device can be used to improve work efficiency. The following preparations should be completed before automatic routing: automatic routing control file (do file) In order to better control the routing quality, generally in Before running, the wiring rules should be defined in detail. These rules can be defined in the graphical interface of the software, but the software provides a better control method, that is, according to the design situation, write out the automatic wiring control file (do file), the software in this file run under control.
