The device model is one of the necessary process library files provided by the foundry to customers. The device model is based on device physics and uses mathematic to describe the performance of device. It uses mathematical equations, equivalent circuits and process data fitting methods to accurately describe the current-voltage relationship of the device. It is an important basis for circuit simulation.
