Another way is to click the run button directly in the icon bar.īelow is the simulation result. To do this, go to Simulate tab then click Run. It is the name you provided when you right click the component text. Take note that parameter name is not a net name. The simulation will result to error when there is no value entered. Take note, in DC sweep, the voltage to be swept must not be empty or zero. Enter the command line pattern above in the white area of the window. To open the spice directive, just press letter T in the keyboard. To use this method, you must use the spice directive. You can make it by using the command line pattern. It is not necessary that you will go to Edit Simulation Command window every time you will do DC sweep. Next is the starting value which is zero then the final value which is 10V then finally the increment of 0.1V. Next to the sweep type is the parameter to be swept. As you notice, the command line starts with a dot then the type of sweep we specified which is a DC sweep. After applying the settings, click OK then drop the command line in the schematic and you can run the simulation.īelow schematic is showing already the command line in the bottom. In below settings we want to sweep the parameter V1 from 0V to 10V with an interval of 0.1V. On below window click DC sweep and apply the settings as shown. After you drawn the circuit, go to “Simulate” tab then click “Edit Simulation Command”.ģ. If this is the first time you do simulation in LTSpice, click THIS guide.Ģ. Open LTSpice and start a new schematic then draw the above circuit. Voltage sweep is the easiest way to do this.ġ. On below circuit we will determine the level of V1 when the VBE clamp to a diode level or the output Vout turns low.

The first way on how to sweep voltage in LTSpice is through a DC sweep command. How to Sweep Voltage in LTSpice using a DC Sweep Command LTSpice can also do current, resistance and temperature sweeping.

Parameter sweeping is very common in simulation wherein you want to know at what particular voltage level the output started to rise, fall and the likes. We will discuss these one by one in this article. There are several methods on how to sweep voltage in LTSpice.

It really does what paid simulation software can do (although not that fast when dealing with analog simulation such as switching power supply). Personally I like LTSpice, aside from being a freeware, it is easy to use. In this article we are going to explore the ways on how to sweep voltage in LTSpice.
