PURPOSE: To perform one-dimensional simulation in a shirt time with a high precision.
CONSTITUTION: This device consists of an initial value input part 1 which inputs an initial physical quantity at the time of estimating the influence upon a one- dimensional simulation area of the multidimensional effect obtained from a two-dimensional area, a two-dimensional effect estimating part 2 which uses the inputted initial physical quantity to estimate the influence, a one-dimensional simulation executing part 3 which determines the variation of a simulation parameter in the one-dimensional simulation area based on the estimated influence and physical relations between the two-dimensional area and the one- dimensional simulation area and executes one-dimensional simulation, and a physical quantity determining part 4 which determines the physical quantity on the one-dimensional simulation area in accordance with the one-dimensional simulation result. Thus, the design efficiency of a semiconductor element is improved.
