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
