Simulation model construction method and simulation method

A simulation model construction method for constructing a simulation model which simulates input-output characteristics of a device and includes a physical model of the device, comprising:

• an input data preparation step of preparing a plurality of pieces of input data to be input into the simulation model;
• a dataset generation step of generating a dataset including the plurality of pieces of input data and an output error relative to a measured value of an output value of the simulation model when each of the plurality of pieces of input data is input into the simulation model;
• a response surface generation step of generating a response surface of the output error for the input data, on the basis of the dataset;
• a feature point identification step of identifying a feature point where the output error is smallest on the response surface;
• a dataset updating step of generating an updated dataset by adding the feature point to the dataset;
• and
• a model optimization step of optimizing a physical parameter included in the physical model using the updated dataset,
• wherein, in the response surface generation step, the response surface is updated using the updated dataset as the dataset,
• wherein, in the feature point identification step, the feature point is updated based on the updated response surface, and
• wherein, in the dataset updating step, the updated dataset is further updated by adding the updated feature point to the dataset.
