    摘要: A system and method for inspecting layout of a printed circuit board (PCB) provides a graphical user interface (GUI). The GUI displays a layout of the PCB. High side pins of a pulse width modulation (PWM) controller and a component connected to a high side pin are found. If the component is a metallic oxide semiconductor field effect transistor (MOSFET), the system calculate absolute a linear distance and a trace distance between a source pin of the MOSFET and a capacitor pin of a coupling capacitor connected to the source pin. If the linear distance, the trace distance and a capacitance of the coupling capacitor accord with a layout standard, the layout of the PCB is determined to be up to standard.
