LTSpice is a circuit simulation software that is used in many ECSE courses at RPI. This module gives an overview of the key functions of the software. For RPI students, by the end of the module you will have all the information you need to complete Proof of Skills: Circuit Simulation for both Intro to ECSE and Electric Circuits.
Customization is optional for most LTSpice users, but if you are a student working on Proof of Skills for your RPI ECSE classes, then customizing your interface is the first thing you should learn how to do.
