Design Rule Check (DRC) After the wiring design is completed, it is necessary to carefully check whether the wiring design conforms to the rules made by the designer, and also to confirm whether the rules made meet the requirements of the printed board production process. Generally, the inspections include the following aspects : Whether the distance between lines and lines, lines and component pads, lines and through holes, component pads and through holes, and through holes and through holes is reasonable, and whether it meets the production requirements.
Are the power and ground wires the proper width, and are the power and ground wires tightly coupled (low wave impedance)? Is there any place in the PCB where the ground wire can be widened.
