PSpice User Guide Setting up analyses and starting simulation October 2019 456 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Extending a transient analysis Often, a long transient analysis will run to the completion time (TSTOP) without achieving the desired simulation results (achieving a steady state, for instance). To achieve better results, the value for TSTOP would have to be increased and the entire simulation would have to be rerun from the beginning. This was time-consuming and inefficient for large simulations. A transient analysis will automatically pause rather than stop when it reaches the TSTOP value. Once paused, you can review the results and determine if the simulation should run longer. If desired, you can increase the value of TSTOP and resume the transient analysis from the point at which it paused, thus saving a good deal of processing time. Note: For more details about using TSTOP, see the online PSpice Reference Guide. To help clarify under what conditions simulations will either be terminated or paused, the following table explains the different behaviors of PSpice for particular simulation scenarios: Simulation scenario Behavior of PSpice Running a single transient simulation using a profile or a circuit file containing one circuit. PSpice will pause after a successful simulation, or if a convergence error occurs, allowing you to change certain runtime parameters and resume the analysis. Running a single AC/DC simulation using a profile or a circuit file containing one circuit. PSpice will stop (terminate) after a successful simulation. -or- PSpice will pause if a convergence error occurs, allowing you to change certain runtime parameters and resume the analysis.
