Recently, an efficient damped pseudo transient analysis method was proposed to find DC solutions for nonlinear circuits. However, the simulation efficiency is still not satisfactory. In this paper, for different kinds of circuits, we get some groups of PTRAN algorithm control parameters values by using a parameter optimization algorithm for pseudo-transient analysis to obtain higher efficiency during...
This paper presents three implementation algorithms of compound elements pseudo-transient analysis to find DC solutions for nonlinear LSI circuits. In former researches, CEPTA was implemented in SPICE-like simulator with the merits that the size of Jacobian matrix is not expanded during the calculation. While the inserted pseudo parts are converted to some certain equivalent circuits, the conventional...
The pseudo transient-analysis method is regarded as one of the most effective method to find DC operating points for nonlinear circuits. In this paper, we combine the ramping method and the damped pseudo-transient analysis algorithm together in order to improve the simulation efficiency. By combing the two algorithms together, the oscillation problem and time-consuming problems can be greatly eliminated...
Recently, the compound element pseudo transient analysis method, CEPTA, is regarded as an efficient practical method to find DC operating points of nonlinear circuits when the Newton-Raphson method fails. In this paper, an effective SPICE3 implementation algorithm for the CEPTA method is proposed. It can significantly improve simulation efficiency with smaller limitations during simulation. Besides,...
