A method for simulation modeling generated based on a first modeling tool and using a second modeling tool including a functional block comprises: an extraction step of extracting a first attribute value generated based on a first modeling tool of a functional block and a second attribute value generated based on a second modeling tool of the functional block; a first calculation step of calculating a first data representation range of the functional block with respect to the first attribute value; a second calculation step of calculating a second data representation range of the functional block with respect to the second attribute value; and determining whether the first data representation range and the second data representation range coincide with each other. Therefore, the method may allow simulation modeling to be done smoothly.
