![]() Nevertheless, as a starting point, test fixtures are often better than a blank slate. They have not necessarily been reviewed by factory applications engineers, and many are simplified they use ideal passive components or they are focused on evaluating how the macromodel handles specific fault conditions. Note that test fixtures are not recommended for production use. These test fixtures, called jigs, are used by the ADI modeling teams for testing and evaluating device macromodels, and are offered as drafting starting points. Most of Analog Devices’ power management and signal chain products that are modeled in LTspice have an associated predrafted test fixture available. If you cannot find a demo circuit for the product you are interested in, there is a test fixture that can act as a starting point for your design. asc file to your local directory and open it. To Use an LTspice Demo Circuit:įind the demo circuit through a product web page or by searching the Demo Circuit database for a part or application. Download the demo circuit. Many are based on available hardware evaluation boards. Demo circuits are reviewed by applications engineering and provide a solid starting point for most designs. These examples can also be found through product and evaluation board webpages under Tools & Simulations. If you are interested in a specific solution, look through ADI’s extensive collection of LTspice examples in the Demo Circuits section. Educational examples installed with LTspice.Demonstration circuits available from LTspice.There are three main sources of LTspice schematics: LTspice schematic files are saved with an. Instead of starting with a blank slate, it is far better to familiarize yourself with LTspice by exploring an existing schematic and reviewing its performance in a simulation. Getting Acclimated to LTspiceĭrafting a circuit from scratch can be a daunting task when using a new tool. To update with the latest models, software, and examples, choose Sync Release from the Tools menu. Sync Release is available under the LTspice Tools menu (Figure 1).įigure 1. To keep your software updated with the latest models, software, and examples, it is important to synchronize your release of LTspice. Downloadable installation files for LTspice are available at /LTspice. LTspice software runs on Windows ® and Mac ® OS X operating systems. Consequently, you can create, encapsulate, and abstract complex circuits with confidence that circuit size and hierarchy are only limited by your computer’s resources and your time. LTspice is provided at no cost to our customers and to the engineering community.* Do not let its free status dissuade you it outperforms many simulation solutions in the market and is not hobbled by any arbitrary limits. Successive simulations allow you to explore the circuit limitations and performance boundaries of your design through minor adjustments, helping to develop your circuit intuition. 1 This is especially important for switch-mode power supply designs, an area where LTspice outperforms many other simulation tools and enables you to iterate your designs in minimal time. LTspice uses proprietary modeling techniques for its macromodels, resulting in fast, accurate simulation results. LTspice includes an extensive library of macromodels covering most of ADI’s power management and signal chain products, as well as a library of passive components. LTspice contains an integrated schematic editor, waveform viewer, and advanced features that are easy to use once you learn some basic commands. The key to most circuit designs is the speed with which you can reach an understanding of your circuit, its correctness, and its limitations, so that you can refine your design and select components before going into the lab to prototype and test. LTspice ® is Analog Devices’ high performance circuit simulation program, which allows you to draft, probe, and analyze the performance of your circuit design. ![]()
