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.
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.
2 Under Options, select Save Bias Point.
3 Complete the Save Bias Point dialog box.
4 Click OK.
