Abstract:
In one embodiment, a method for reducing power supply noise within an electronic system that includes an integrated circuit (IC), a package, and a printed circuit board (PCB) connected by a plurality of power delivery networks (PDN) is disclosed. Power supply noise within the system is reduced by defining a voltage compression limit for each PDN of the electronic system; determining a voltage compression for each PDN of the electronic system during a plurality of switching events; comparing the voltage compression of each PDN of the electronic system to the voltage compression limit for each switching event; and in response to the voltage compression of each PDN of the electronic system exceeding the limit, modifying the electronic system to reduce the voltage compression below the limit.
