Temporal shift in threshold voltage and a new parameter called \"healability\" are used to characterize the state of the NBTI effect. The NBTI degradation is then simulated as a trace of the interpolated characterization parameters. Thereby, healability is crucial for the success of the model. The phase space based model is well suitable in performance oriented use cases, since a small deterioration of the simulation results comes with a vastly improved simulation speed. The additional phase space dimensions of temperature and supply voltage in combination with the conversion between duty cycle and supply voltage permit a performance effcient way to simulate NBTI degradation for complete circuits without disregarding power gating, temperature profiles and the IR drop.}}@COMMENT{Bibtex file generated on }
