Abstract
An IC design computer simulation tool is provided with a design reader equipped to assign device characterizations to electronic devices of an IC design, and model evaluators equipped to adaptively perform model evaluations in accordance with the electronic devices' assigned device characterizations. In one embodiment, the electronic devices include transistors, and the adaptive model evaluations provide evaluated model quantities to support solution of the circuit node voltages using fully coupled (implicit) or partially decoupled (explicit) solution techniques. In particular, the transistor capacitive coupling currents are expressed according to the assigned device characterizations.
