Troubleshooting memory errors

If you receive a "simulator out of memory" error, do some or all of the following to generate less data: 

  • Place fewer probes on the design (plot fewer variables at a time)
  • For Transient or Interactive simulation, increase maximum time step size in the Simulation settings 
  • For Transient or Interactive simulation, change simulation start time so that the grapher just displays the time range you are interested in
  • For AC sweep, decrease the number of points calculated
  • For DC sweep, decrease the number of nested sweeps
  • Stop the simulation when not needed
