Since BTI in ultrascaled devices is a stochastic mechanism and aging must be evaluated under the actual operation conditions of devices in the circuit, SPICE and Monte Carlo simulations are customary combined with this purpose. The key point in these simulations is the correct description of the BTI effects in the device and their inclusion in circuit simulators. In this subchapter, the different adopted approaches are presented, pointing out their pros and cons, and illustrated with examples of BTI effects on several analog and digital circuits.
