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.

摘要： A system for optimizing a current overload protection circuit includes an input device, a data storage device, a central processing device, and a display. The central processing device includes a storage module, a control module, and a calculation module. The storage module stores a VI application therein. The control module receives instructions from the input device and selects virtual electronic components of the current overload protection circuit from the data storage device and connection of the selected electronic components. The current overload protection circuit is completed and run in the VI application; electronic components significantly affecting the maximum protection current are labeled. The calculation module calculates normal distribution samples of the current overload protection circuit based on the labeled electronic components. The display shows whether the current overload protection circuit meets a process capability standard.
