Abstract
This paper presents a numerical approach that combines the finite-element time-domain (FETD) method and the finite-difference time-domain (FDTD) method to model and analyze the two-dimensional electromagnetic problem concerned in the simultaneous switching noise (SSN) induced by adjacent signal traces through the coupled-via parallel-plate structures. Applying FETD for the region having the source excitation inside and FDTD for the remaining regions preserves the advantages of both FETD flexibility and FDTD efficiency. By further including the transmission-line simulation, the signal integrity and power integrity issues can be resolved at the same time. Furthermore, the numerical results demonstrate which kind of signal allocation between the planes can achieve the best noise cancellation. Finally, a comparison with the measurement data validates the proposed hybrid techniques. © 2007 IEEE.
