You can change component label if you want to by right clicking on the default component name and then encode a new name then OK. To put a ground, click the symbol on the right of the wire symbol above. To put a net name such as Vcc, Vin and Vout, click icon below and type the name.Īnother approach to put a net name is by pressing “F4” in your keyboard.Ĭlick this to draw a wire and start connecting components.Īnother method is to press “F3”. Or by simply typing letter “R” from your keyboard.ĭouble click opamps to select specific device. If you are a 100% naive on LTspice, consider reading this post.Īnother way to display above window is by clicking “F2” in your keyboard. Once the program is running, start or open a new schematic. If you don’t have one yet, click here to download. We will start the Monte Carlo Simulation using LTspice by of course opening your LTspice software. Monte Carlo Simulation using LTspice Step by Step Tutorials Step 1. We are going to sweep the level of Vin from 0V to 20V and observe the voltage range when the output changes state. We can simulate this using DC sweep command. Initially the output is low because Vcc is already stable before the level of Vin starts to rise. I mentioned voltage range because we are dealing here with tolerances. In this tutorial we will find out what is the voltage range of Vin wherein the output changes state from low to high. The output is high or equal Vcc otherwise.

The output will be zero if the value of Vref is higher than Vin+.

Our circuit model in this monte carlo simulation is a comparator as shown in Figure 1 below. Monte carlo is an analysis method used by design engineer to increase the robustness and reliability of their products. In this article I will teach Monte Carlo Simulation using LTspice with Step by Step Tutorials. Thanks for Linear Technology for sharing such a nice tool. LTspice is a very good circuit simulation tool for electronic circuits.
