In this paper, we propose a parameter optimization algorithm for the EMC macro-modeling of IC/LSI power currents called the LECCS(Linear Equivalent Circuit and Current Source) model. The unnecessary electro-magnetic wave from a digital electric device causes an electromagnetic interference to other apparatus, and thus, its reduction has been emphasized as one of the highest priority issues in digital electric device design societies. In order to simulate accurately high frequency current from the power-supply system in IC/LSIs that is its primary resource, the LECCS model has been proposed as a linear macro-model of a device power-supply circuit. In the LECCS model, the circuit between the power supply and the ground in a circuit is described as a combination of RLC-series circuits in parallel. Given a set of measured impedances at various frequencies, our algorithm first finds the number of RLC-series circuits from the number of valleys, and then, it searches optimal values of RLC parameters by the local search method. The validity of our algorithm is verified through applications to the results of a real device where the accuracy and the required processing time in our result are compared with those by the manual model tuning. |
