Abstract
A method and apparatus for adaptively tuning an integrated circuit are disclosed. For example, an integrated circuit (IC) comprises a monitored path comprising circuit elements operating on a clock signal, where a last circuit element of the circuit elements comprises a first flip flop. The IC also comprises a second flip flop operating on an early clock signal, where the early clock signal is phase shifted from the clock signal, and where the second flip flop is coupled to the monitored path prior to the last circuit element. The IC also comprises a transition detection module for detecting when an output from the first flip flop toggles, and an error prediction module to detect a potential error on the monitored path. The IC comprises a controller that is configured to scale a voltage or a frequency of the IC.
