A method for noise suppression for a system implementation of an integrated circuit design is described. First clock operating parameters for logic blocks of the integrated circuit design are obtained. Second clock operating parameters for input/output banks of the integrated circuit design are obtained. At least one switching frequency associated with at least one power supply source is obtained. First and second capacitor values for the at least one power supply source are determined responsive to the first clock operating parameters, the second clock operating parameters, and the at least one switching frequency. The first capacitor values are associated with a first frequency range of operation and the second capacitor values are associated with a second frequency range of operation which is higher than the first frequency range of operation. Third capacitor values for suppression of anti-resonances are determined.
