Abstract
To specify high-risk error positions in consideration of effects of electromagnetic noise flowing through a printed wiring board. A design rule check system (1) includes a pattern information acquisition unit (11) for acquiring a layout pattern of a board to be checked, a design rule check unit (12) for carrying out a design rule check on the layout pattern, a current calculation unit (13) for calculating distribution of noise current values on the board based on the layout pattern, a weighting unit (14) for adding a weight to a result of the design rule check according to the magnitude of the noise current values calculated by the current calculation unit (13) and corresponding to each error position detected through the design rule check, and an error information generation unit (15) which generates information indicating a risk level of each error position based on the weight.
