LTspice IV: Waveform Viewer

Gabino Alonso - Strategic Marketing Engineer Jul 22nd 2011


LTspice IV includes an integrated waveform viewer that in combination with the schematic editor provides an easy way to display and review simulation data. This means that if you click on an object in the schematic editor, the voltage on that wire or current through that component will be plotted on a waveform viewer and some basic measurements can be taken. This video provides an introduction to the use of LTspice waveform viewer in the analysis of a simple circuit so that you can review edits of your design quickly.



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.

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
