5.1 Aiding in Convergence

By default, PSpice®-for-TI does not have AutoConverge turned on. If there are convergence issues, check the datasheet of the device to verify setup and operation within the linear operating conditions of the device.

When working with complex projects the simulation takes a while (a couple of minutes) even within linear operating conditions of the device. AutoConverge can be turned on in the simulation profile settings to reduce the simulation time. Under the Options tab > Analog Simulation > Auto Converge, selecting the top AutoConverge text box selects all options below.

AutoConverge can reduce the accuracy of simulation or increase the amount of iterations as the program tries to reach convergence.
