An integrated circuit (IC) comprising:

• an adaptive voltage scaling (AVS) controller configured to control a voltage supplied to a portion of the IC;
• and
• at least one sensor configured to sense at least one state of the IC and to provide an output signal indicative of the at least one sensed state to the AVS controller,
• wherein the IC has a first setting and a second setting, the AVS controller being configured to use the output signal to control the voltage in the first setting and the AVS controller being configured to control the voltage independently of the output signal in the second setting.

A method comprising:

• providing an integrated circuit (IC) having a nominal operating voltage and an adaptive voltage scaling (AVS) controller configured to control a voltage provided to a portion of the IC;
