Circuit simulation with decoupled self-heating analysis

摘要

A solution of a first set of equations of the time-varying electrical response of a circuit is determined between pairs of adjacent time points t_i and t_i+1 based on predicted electrical responses of the devices at time point t_i+1 and as a function of the initial temperatures of the circuit devices at time point t_i. A solution of a second set of equations of the time-varying temperature responses of devices of the circuit is determined (1) after each iteration of the first set of equations and as a function thereof or (2) at each time point t_i+1 and as a function of the solution of the first set of equations at the time point to determine the corresponding temperature response of the circuit. The solutions of the first and second sets of equations at one or more of the points in time are displayed.
