Evaluating a PDN based on jitter

Power distribution networks (PDN) must supply current fast enough to meet the switching needs of high-performance integrated circuits. As the voltage regulator module can only supply current up to a limited frequency range, decoupling capacitors are added to the PDN to provide a low impedance path for current to flow to the IC. This paper describes a simulation methodology to automatically measure jitter caused by a PDN and use the results to evaluate the quality and effectiveness of PDN decoupling, since reducing jitter can improve the performance of a data-driven interface
