This paper considers the repeated-executing characteristics of circuit simulators in practical situations, and raises according methods. These 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.
