Abstract
A printed circuit board design assisting method, device and storage medium are provided. The assisting method includes referring to the position of terminals of a grid array package part, and attributes indicating whether each of the terminals is a power source terminal or a ground terminal, and selecting the power source terminals as a terminal to be researched, searching for a new connection path between the terminal which has been selected, and one of the ground terminals, by way of a first decoupling capacitor, determining whether there is duplication of paths between the new connection path and an connection path between the terminals connected by way of a second decoupling capacitor, changing the position of the second decoupling capacitor if duplication is detected, and re-searching a connection path between the terminals by way of the second decoupling capacitor, which is not in duplicate with the new connection path.
