Models that predict device and interconnect degradation over time, such as aging of threshold voltage and drive current, used in circuit simulation to check that designs meet lifetime targets.
Model Work product in the Process design kit (PDK) development lifecycle
It lets designers check that circuits work at end of life, not only when new. Timing and analog margins otherwise erode in the field, and designs either fail late or carry excessive guard bands.
