Abstract (in Japanese) (See Japanese page) 
(in English) For simulating high-frequency power-supply currents generated by an LSI chip, EMC macro-model called LECCS model composed of a linear equivalent circuit and internal equivalent current sources was proposed. This LECCS model has been extracted in the condition that supply voltage remains steady. However, supply voltage fluctuates depending on the high-frequency currents on the power distribution network (PDN). In this report, the authors propose a modeling method in which a LECCS model for each block unit is extracted from the design information of the LSI and
the sub-block models are combined to construct a functional block model
with the internal equivalent current sources representing the effect of fluctuations in supply voltage. Applying this method to a test chip designed by the authors, the LECCS model expresses high-frequency currents with good accuracy.
