Pspice simulation speed issue

suresh rajaram

I am running a model with the below settings is taking almost half a day. Is there anything i can improve from the below setting? How can i increase the minimum time step by modifying the below parameters although it is calculated automatically?

Hi Suresh,

There's an FAQ for failure to converge (not your problem) but it also discusses some of the settings that can be adjusted which may help speed simulation.
