Abstract
A new low-cost multichip module (MCM) topology, the interconnected mesh power system (IMPS), has been shown capable of reducing the metal layers of a conventional four-layer MCM by half. To provide a complete MCM on only two metal layers, the IMPS topology provides a unique and complex power distribution system and signal transmission environment. This paper reports on models of the IMPS structure based on finite-difference/partial-inductance methods and PSpice simulation. The models can easily he constructed using a commercial three-dimensional (3-D) field solver and the circuit models can be solved by PSpice. The agreement between the modeled and measured results is excellent. Discrepancies between models and results are also discussed.
