Nexxim Simulator > Nexxim DC AnalysisDC (direct current) analysis first initializes the circuit, then solves the circuit equations to derive the DC operating point. The DC operating point consists of the voltages at all nodes and currents through all branches and includes the DC bias voltage applied to semiconductor devices. DC operating point analysis also provides the initial values used as the starting point for DC sweep analysis, harmonic balance, and transient analysis, unless these are set by the user. It also provides the large-signal bias operating point for small-signal AC analysis, noise analysis, and linear network analysis. Successful and accurate calculation of the DC operating point is essential for these simulations. For details on DC sweep simulations, refer to the separate topic on Variable Sweep.
The topics for this section include: Viewing DC Bias Voltages and Currents in a Schematic Running DC Analysis from the Schematic Editor DC Operating Point Statement in a Netlist Convergence, Speed, and Accuracy
