PSpice User Guide Setting up analyses and starting simulation October 2019 431 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. When you run the simulation with AutoConvergence set, PSpice initially runs using the normal values for the specified simulation time. However, if the simulation does not converge, PSpice changes the values within the relaxed limit for the parameters selected in the Autoconvergence Option. Note: Autoconverge can also be set from the PSpice Runtime Settings dialog box. Where, you can also set Enable Advanced Convergence Algorithms. If convergence is not achieved at the end of the complete run, PSpice starts simulation with an initial relaxed value if you the Restart option is selected. Note: PSpice also changes the minimum time step size during a simulation to achieve convergence. Although PSpice starts with the default minimum time step size, it can heuristically decide on a smaller time during the simulation. Tip You can specify the relative factor by which the minimum time step size is changed by setting the value of Relative factor for minimum delta (DMFACTOR) in the General node of the Advanced Analog tree structure. You can set any value that is a factor of 10 and is less than or equal to 1, such as .1, .001, or .0001. For example, if the default value of the minimum time step size is , you can specify DMFACTOR as .1. This will result in a minimum time step of . 10 18 – 10 19 –
