Reducing computations in SPICE with node-reduced multiterminal representations of semiconductor devices

摘要

Multiterminal representation (MTR) of a subsystem constitutes the central concept in the analysis of a large-scale physical system through its subsystems. A new nodal reduction technique is developed to further reduce the number of nodes in a nodal-admittance MTR. The results of the implementation of MTR's in the circuit simulator SPICE show that the nodal-reduced MTR achieves an improvement in processing time while maintaining the same simulation accuracy.
