Normally, a dc operating point analysis is performed before starting the transient analysis. operating solution and use user-specified initial conditions. If Tstart or dTmax is specified, Tstep must be specified. The final parameter dTmax, is the maximum time step to take while integrating the circuit equations. This is a means of managing the size of waveform files by allowing startup transients to be ignored. However, if Tstart is specified, the waveform data between zero and Tstart is not saved. Transient analyses always start at time equal to zero.

LTspice uses waveform compression, so this parameter is of little value and can be omitted or set to zero. Tstep is the plotting increment for the waveforms but is also used as an initial step-size guess. Test signals are often applied as independent sources or may be taken from captured data stored on file. It basically computes what happens when the circuit is powered up and runs. Selected circuit signals may be displayed in the Waveform viewer as they are simulated, much like an oscilloscope on the bench.

The Edit Simulation Command dialog box organized like a row of tabbed index cards:

At the netlist level the Simulation Command is simply a line of text that begins with any of the following Dot Commands:Īt the schematic level these commands may be entered directly as a SPICE Directive ( ctrl-right-click on the text to edit) or may be entered via the drop down menu item: Simulate => Edit Simulation Cmd.
