It is a commercial software and offers a wide range of features for electronic design, including circuit simulation, PCB layout, and microcontroller simulation. Proteus, on the other hand, is a circuit simulation and PCB design software developed by Labcenter Electronics. It's also available for multiple platforms such as Windows, Mac and Linux. Additionally, LTSpice has a powerful built-in waveform viewer, which can be used to analyze the simulation results. It also has a user-friendly interface, making it easy to use for both beginners and experienced users. It has a large library of models and components, allowing users to simulate a wide variety of circuits.
It is a free, powerful and easy-to-use tool for simulating analog circuits.
LTSpice is a high-performance SPICE simulation program developed by Linear Technology, now part of Analog Devices.
LTSpice and Proteus are both popular circuit simulators, but they have different features and capabilities.
