Abstract

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.
