LSI model to simulate high frequency current on printed circuit board

摘要

A LSI macro model to simulate high frequency current on power and ground planes of printed circuit board (PCB) for EMI estimation has been developed. The simulated value of current on power supply line of a PCB with standard logic circuits using developed model agrees with the simulated value using transistor level model with average 2dB difference. And a methodology to generate macro model parameter with measurement has been developed. Simulated value of current spectra on power supply line of a PCB using macro model whose parameter is generated with the methodology agrees with measured value within 4dB difference.
