A novel method is proposed to analyze simultaneous switching noise on the conductive planes in high speed MCM layout system,which is based on PEEC combined with block reduction algorithm and the recursive convolution formulation.Its advantages are simple parameter extraction,high efficiency and high precision.Meanwhile,a hierarchical modeling way is proposed to model big size power/ground planes by cascading macromodels of small size power/ground planes.The simultaneous switching noises are directly analyzed in time domain.At last,the precision is not only verified by the plane circuit formulation,but also two examples further indicate that the method gives high accuracy and high efficiency for time domain simulation of simultaneous switching noise on the conductive planes in high speed MCM.
