Abstract
A system for reducing undesired radiation generated from an LSI, comprises: a first storage part,for storing a circuit connection information for the LSI and a current waveform of an undesired radiation source of the LSI; a transfer function calculating part,for calculating a transfer function of undesired radiation, which is transmitted from an undesired radiation source in the LSI to a power source terminal connected to the outside of the LSI, on the basis of the circuit connection information and the current waveform; a second storage part,for storing a constraint on an impedance added in the vicinity of the undesired radiation source, and an allowable level of undesired radiation at the power source terminal; and an undesired radiation optimizing part,for calculating an impedance, which causes the undesired radiation at the power source terminal to be less than or equal to the allowable level, using the transfer function under the constraint. Thus, undesired radiation generated from the LSI is reduced.
