Dynamic adjustment of operating conditions of integrated circuits

A method of dynamically adjusting an operating conditions of an integrated circuit, comprising:

• receiving, from a voltage reference module, an operating voltage of the integrated circuit, wherein the operating voltage is distributed in a power grid that drives a plurality of circuit blocks of the integrated circuit;
• receiving, from a clock generator, a reference clock, wherein the reference clock is used as an operating frequency of the integrated circuit and is distributed to by the plurality of circuit blocks in the integrated circuit;
• measuring, by a circuit performance monitor, feedback path timing information of one or more circuit blocks in the plurality of circuit blocks, wherein the circuit performance monitor includes one or more replica feedback paths corresponding to one or more feedback paths in the one or more circuit blocks, and wherein the feedback path timing information includes feedback path delay data of the one or more replica feedback paths;
• comparing, by a performance adjuster, the feedback path timing information of the one or more circuit blocks to the reference clock;
• determining timing margins of corresponding one or more feedback paths of the one or more circuit blocks based on the comparison;
• and
• generating, by the performance adjuster, a feedback for adjusting the operating voltage or the operating frequency of the integrated circuit based on the timing margins of the one or more feedback paths of the one or more circuit blocks.
