LTspice: Stepping Parameters

Gabino Alonso - Strategic Marketing Engineer Feb 9th 2012


Plotting voltages or currents in a LTspice simulation is important but so is varying a parameter in a device or model so that you can compare performance and develop your circuit intuition. There are two ways to examine a circuit by changing the value of a parameter. You can either manually enter each value then re-simulate the circuit or you can use the .step command to sweep across a range of values in a single simulation run and have a side by side comparison. This video provides an overview of the basics steps of how to use the .STEP command to perform repeated analysis of a circuit in LTspice.
