A design method for displaying a DRC in a classification manner in a PCB design is provided. The design method includes: acquiring layer information contained in a current design, adding the acquired layer information to a DRC Layer menu in a pop up window, acquiring a DRC Type contained in the current design and adding the processed DRC Type to a DRC Type menu in the pop up window after processing the acquired DRC Type; creating an updating function, to update a DRC Type menu list in response to an input action of a user; acquiring an attribute of each item in a DRC Layer menu list and the DRC Type menu list, and inserting the acquired attribute into the updated DRC Layer menu list and the updated DRC Type menu list, to form a feature parameter list.
