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.
