Save and Load Bias
Point
Save Bias Point and Load Bias Point are used to save and restore
bias point calculations in successive PSpice A/D 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 Analysis Setup dialog box, click Load Bias Point.
2
Complete the Save Bias Point dialog box as described in the
Schematics User’s Guide. Click OK when finished.
3
Make sure the check box next to Save Bias Point is selected
(
