Automatic Partitioning And Dynamic Mixed-mode Simulation

This paper first describes a new program called isPLIT, which reads in a transistor netlist, automatically recognizes gate-level and user-defined components, substitutes higher-level models for them, and writes out a netlist suitable for a mixed-mode simulator. The paper also describes a dynamic mixed-mode simulator called iSPLICE3d. The dynamic simulator is able to switch between different models of a circuit during the course of the simulation when, it determines that a higher level model is not suficient for simulation accuracy. When used together, iSPLIT and the dynamic mixed-mode simulator can be a powerful framework for the simulation of mixed analog and digital circuits.
