Improvement on chip-level electrothermal simulator-ILLIADS-T

In this paper, improvements on the previously developed chip-level electrothermal simulator, ILLIADS-T, are presented. The improved version (ILLIADS-T2) enhances the efficiency during uncoupled electrothermal simulations by taking advantage of the potential latency of circuit blocks. The generalized variable-grid system for numerically simulating heat flow in composite materials is also developed and presented.
