Save and load bias point Save Bias Point and Load Bias Point are used to save and restore bias point calculations in successive PSpice simulations. Saving and restoring bias point calculations can decrease simulation times when large circuits are run multiple times and can aid convergence. If the circuit uses high gain components, or if the circuit's behavior is nonlinear around the bias point, this feature is not useful. Save/Load Bias Point affect the following types of analyses: ■ transient ■ DC ■ AC Save bias point Save bias point is a simulation control function that allows you to save the bias point data from one simulation for use as initial conditions in subsequent simulations. Once bias point data is saved to a file, you can use the load bias point function to use the data for another simulation. To use save bias point 1. In the Simulation Settings dialog box, click the Analysis tab. See Setting up analyses on page 419 for a description of the Analysis Setup dialog box. 2. Under Options, select Save Bias Point. 3. Complete the Save Bias Point dialog box. 4. Click OK.
