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 pre-corrected FFT approach. Speedups of 60/spl times/ and memory reductions of 12/spl times/ are shown for real engineering problems, as compared to direct integral equation solutions.
