Abstract
In an embodiment, a circuit configured for asymmetric ageing prevention in an integrated circuit (IC) comprises a primary clock configured to generate a primary clock signal, a secondary clock configured to generate a secondary clock signal, a state determination circuit, and a control circuit. The state determination circuit is configured to determine a current operating state associated with at least one of a primary clock condition and a power-on-reset condition in the IC. The control circuit is configured to generate a control signal in response to a determination of an first operating state. The control signal is configured to facilitate a transition from the primary clock to the secondary clock upon determination of the first operating state, and a transition from a safe operating mode to a normal operating mode upon determination of a second operating state. The secondary clock is associated with a safe operating mode of the IC.
