Software Description

Circuit simulation has taken a central role in the design and education of electronics. Designing power supplies, analyzing amplifier circuits, or studying the basics of electronics, accurate simulation tools will save you the expensive mistakes of prototyping. LTspice offers these simulation features in a free, professional-quality SPICE simulator by Analog Devices.

LTspice provides full circuit simulation capabilities including a large component library and analysis capabilities. The software offers simulation tools that engineers and students cannot do without:

  • Schematic capture interface. The software has easy to use drawing tools to draw circuit diagrams using drag and drop components and automatic wire routing.
  • Unlimited circuit size that enables simulation of complex designs without node or component limitations.
  • Large component library with proper models of Analog Devices components and generic components.
  • Various types of analysis such as transient, AC, DC, noise, and Monte Carlo simulations.
  • Advanced measurement and mathematical operations waveform viewer.
  • Import and export of SPICE netlists to be compatible with other tools.
  • Large project with subcircuits support using hierarchical design.
  • Parameter sweeping to study the behavior of a circuit under component variations.
  • Switch-mode power supply design efficiency reporting.
  • Proprietary component data encryption.

The program basically turns your computer into an electronic laboratory. LTspice can be used to test simple LED circuits, as well as optimize complex switching regulators, and it makes accurate predictions of the behavior of real-world circuits.

LTspice is a program that solves mathematical equations that model the behavior of electrical components. When you simulate, the software will compute voltages and currents all over the circuit at a given time interval. The engine employs sophisticated algorithms to deal with non-linear elements and convergence issues, and the results are close to physical circuit measurements.

The software is available on Windows and macOS operating systems, and can be used on Linux through WINE. Although it is free, it has professional features that are normally available in commercial simulators that are very costly.

LTspice offers the simulation capabilities required to analyze and optimize circuits to any person interested in electronics design or education. To begin simulating circuits without licensing fees or restrictions, download the software on the Analog Devices web site.
