LTspice IV: Stepping Parameters
Feb 9th 2012
Plotting voltages or currents in a LTspice IV 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 IV.
The Linear Technology LTC6954_GUI is used to communicate with the LTC6954 clock driver. It uses the DC590 to translate between USB and SPI-compatible serial communications formats.
LTspice® IV is a powerful, fast and free simulation tool, schematic capture and waveform viewer with enhancements and models for improving the simulation of switching regulators. Click here to download LTspice IV
To launch a ready to run LTspice demonstration circuit for this part:
- Step 1: If you have not installed LTspice on this computer, download and install LTspice IV
- Step 2: Once LTspice is installed, click on the link(s) below to launch the simulation
- Step 3: If LTspice IV does not automatically open after clicking the link above, you can instead run the simulation by right clicking on the link and selecting "Save Target As." After saving the file to your computer, start LTspice and open the demonstration circuit by selecting 'Open' from the 'File' menu
