What is LT spice?

LT Spice is an analog circuit simulator. Based on SPICE (Simulation Program with Integrated Circuit Emphasis), a general-purpose open-source analog electronic circuit simulator. A circuit simulator uses the power of a computer to virtually simulate an electronic circuit and figure out what would happen without the need to create the circuit.


Created by semiconductors manufacturer Analog Device (originally known as Linear Technology), it is the widely used and distributed software which uses SPICE in the industry. It has a freeware license, but LT spice is not restricted to capabilities like node limits, component limits and subcircuit limits.

Features of LT spice:

1.      Free to use: LT spice has a freeware license, which means that it is safe and free to use. This does not mean that it lacks in any way from the paid programs. It has all features which are present in most SPICE programs.

2.      Easy to use: Lt spice has a very easy to use a style of design for its UI. It is very easy to use LT spice if you are a beginner to SPICE programs. You just need to open the program, but all the components you want your circuit to have, define the parameters like voltage and ampere and start the simulation.

3.      Constantly updated: The developers of LT spice constantly update this app. It was created 21 years ago, but it is constantly being updated with the latest release in 2020. There were many flaws in this program which were resolved only with the help of suggestions by its community. The community is very active and helps new users to get their way around the program.
