Abstract
A method for designing a power distribution network (PDN) for a system implementing a target device includes computing a target PDN impedance value for the PDN. For each switching frequency of the target device where an effective PDN impedance value for the PDN is greater than the target PDN impedance value, one or more decoupling capacitors for one or more capacitor types are identified to add to the PDN to drive the effective PDN impedance value below the target PDN value. A selection of decoupling capacitors identified is refined to reduce one or more of a cost of the PDN and space required for implementing the PDN.
