Simulating circuits

Many software packages and online tools can simulate the behavior of circuits. Here we summarize LTspice, a free download for MacOS and Windows from Analog Devices. If the link breaks, just search "LTspice."

The Windows interface is fairly intuitive to use, while the MacOS interface is not. Below is a brief tutorial to get you started on the Mac; it should be easy to replicate these steps on Windows. You can also find video tutorials online, from Analog Devices and other sources.

Below is an example circuit and the output of the simulation. At the bottom of this page, you can download some sample circuits to test.
