Less obvious is the Component button (F2) which opens a vast catalog of available parts and systems which are included by default with LT Spice IV. They can all be accessed with hotkeys which are intuitive for common components: (R) Resistor, (L) Inductor, (C) Capacitor, (G) Ground, (D) Diode.

These are the basic tools on the toolbar along the top of the Schematic Editor. You can import external libraries to add a specific part using generic Spice files easily if you need to make a specific simulation with parts you have specced in advance. LT Spice IV differs from other Spice simulators in that it was developed by and populated with Linear Technology devices. Learning to use a SPICE Simulator is especially useful for classes with analog electronic circuit analysis (EE330 & EE430). It also functions as a great schematic editor if you just need to draw up a general schematic for your project or for a technical report. SPICE Simulators are very powerful tools for circuit analysis. Included in this download are LTspice IV, Macro Models for 80% of Linear Technology’s switching regulators, over 200 op amp models, as well as resistors, transistors and MOSFET models. Our enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. LTspice IV is a high performance SPICE simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. I think that Linear Technologies, maker of LT Spice IV, gave a great description of the program on their download page: This is the tip of the iceberg when it comes to using circuit simulation tools, and hopefully will get you to the point where you can start learning comfortably on your own. This guide provides a cursory overview of basic use of the software, and should allow you to explore its capabilities with some confidence. This is by no means a comprehensive guide, and is only for introduction and basic circuit construction purposes. Even if you don’t plan to focus in electronics, familiarity in a SPICE simulator will enrich your learning experience for required analog electronics courses (EE330 & EE430) and is handy for design problems you may face at some point in your career. SPICE simulators are extremely important in analog circuit design and are practically required for anyone interested in a Microelectronics Focus. Most of this information was compiled by experimentation and online guides which I have used in the past to develop my abilities to use this software. The purpose of this document is to give a basic guide to getting started in using LT Spice IV SPICE simulator and show some examples of things you can do.
