    Abstract: Provided is a semiconductor device simulation system using region graph. The semiconductor device simulation system comprises: a region graph generation module for generating a region graph using a device structure file of a semiconductor device to be simulated; a device determination module for determining a type of semiconductor device for the region graph using a trained graph artificial neural network; an initial solution generating module for generating an initial solution for a device structure corresponding to the type of semiconductor device; and a semiconductor device simulator for performing semiconductor device simulation using the initial solution. The semiconductor device simulation system accelerates the speed of performing semiconductor device simulation by providing an approximate initial solution to the device structure to a semiconductor device simulator.
