Convergence, Speed, and Accuracy

DC operating point simulation provides the large-signal bias point that is important for small-signal analyses such as AC analysis, transfer function analysis, noise analysis, and linear network analysis. These small-signal simulations cannot be performed without a DC solution. Because the duration of the DC analysis is added to the small-signal simulations, it is important to achieve fast DC convergence with high accuracy.

The DC analysis must of course converge in order to obtain a usable result. Once convergence is achieved, the trade-off between solution accuracy and convergence speed can be considered. The options in the following topics affect the convergence, accuracy, or speed.
