Abstract
The invention provides a modeling method and device for a semiconductor device model. The method comprises the steps of determining at least one temperature interval according to a historical simulation result of an integrated circuit device; for different temperature intervals, extracting corresponding device model parameters, and building corresponding sub-device models according to the model parameters; combining the sub-device models to obtain a current semiconductor device model; when the integrated circuit device needs to be simulated again, receiving a current identification value of atemperature interval, and determining a corresponding sub-device model in the current semiconductor device model according to the current identification value; simulating the integrated circuit deviceby using the corresponding sub-device model. Therefore, different temperature intervals correspond to different sub-device models, so that when the integrated circuit device is simulated, no matter what range the temperature is in, the suitable sub-device model can be used for simulating the integrated circuit device, the simulation precision is ensured, and the simulation requirement is met.
