LTspice is known for being the most widely used free SPICE simulator in the industry. It was originally created by Linear Technology, hence the LT in its name, and was later acquired by Analog Devices who continues to support it. LTspice is a high performance SPICE simulator, schematic capture, and waveform viewer with enhancements and models for making simulation of analog circuits easier. By the way, the strange KiCad results I was getting turned out to be user error. I decided to download it and give it a try. While doing some research on what packages were available, LTspice kept popping up. While doing a circuit simulation in KiCad for another article ( Performing A Circuit Simulation In KiCad) and getting some strange results, I wanted to verify those results with a different SPICE simulator. The LTspice schematic created for this tutorial is available on GitHub for your reference. It enables you to discover and correct issues before actually building your circuits in hardware. LTspice is an extremely valuable tool for designing and simulating analog based circuits.
A basic understanding of electronics is expected. This tutorial will teach you how to create a circuit schematic, perform a simulation, and view circuit waveforms in LTspice for Mac.
