Incremental Circuit Simulation and Simulation-on-demand based on Backward-traversing Waveform Relaxation and Portion-simulating Algorithms
Chun‐Jung Chen · Physics Procedia · 2012
In this paper, the practical behavior of circuit simulator users are considered and utilized to speed up the circuit simulation. The used methods are incremental simulation and simulation-on-demand (SOD, just simulate the portion of circuit contributing to user-wanted outputs). A specialized relaxation-based algorithm, Backward-traversing Waveform Relaxation (BTWR), is adopted as the fundamental simulation algorithm. All proposed methods have been implemented and tested. Experimental results justify the values of proposed methods.
