A core frequency-loss estimation methodology for a power-delivery network with reduced decoupling capacitance

This paper proposes a simulation methodology to quantify the relative impact to the maximum CPU core operating frequency, also known as Fmax, for different power-delivery network designs. Good measurement-simulation correlation for designs with different decoupling capacitance has been presented to validate the proposed technique. Through careful consideration of the process, voltage, and temperature in the simulation, together with the availability of more accurate simulation tools to characterize the power-delivery network, good agreement with measurement data has been obtained.
