Abstract

A mixed-mode simulator is described that can simulate voltage fluctuations in the power supply network. Current flow due to logic events is taken into account in order to predict the voltage fluctuations. The difference between the maximum voltage fluctuations calculated by the proposed mixed-mode simulation and these calculated by conventional circuit simulation are within 20%, and we demonstrated the feasibility of the proposed simulation by simulating an entire MOS memory chip (36,000 transistors) in 75 minutes on an HP9000/735
