The use of accelerated full-wave modeling to analyze power island coupling in a hyperBGA SCM

Presented here are results and recommendations for reducing coupling between adjacent power islands based on full-wave simulations of a HyperBGA SCM (single-chip module). These simulations highlight the use of IBM's internally developed accelerated full-wave solver based on the precorrected fast Fourier transform approach. Speedups of 100 × and memory reductions of 12 × are shown for real engineering problems, as compared to direct integral equation solutions. © 2007 IEEE.
