Getting started

Easy Circuits is divided into two major sections: projects and libraries.

To get started follow these simple steps:

  1. For best experience, Easy Circuits needs access to the LTspice® symbol library. If LTspice® is not installed, download it from Analog Devices, Inc. web site.
  2. Open Easy Circuits and from the Libraries page, use 'Add Library' command to add the LTspice® symbol library. It is located in your documents folder (...\Documents\LTspiceXVII\lib).
  3. On the Projects page, add a directory containing your LTspice® projects.
  4. You're all set!

Home page

Home page is your starting point. From here you can open recently used or pinned documents. Quick shortcuts for adding projects and libraries are also located on the home page.
