Abstract
Systems and methods for reducing power distribution network noise are provided. For example, in one embodiment, a method includes determining delay variations of a user design via a delay sensor of an integrated circuit (IC). The delay variations are associated with voltage variations of the user design. Low frequency components of the voltage variations are filtered via control logic of the IC to obtain an AC response of the user design. An artificial current load is introduced to the IC to negate the AC response of the user design.
