Pspice Vs Ltspice

Pspice and Ltspice are two widely popular circuit simulation software tools used in the engineering industry. Both programs provide a user-friendly platform for designing and analyzing electronic circuits. While both tools have similar capabilities, there are features that distinguish them from one another. In this article, we will go through a comprehensive comparison between the two programs.

What is Pspice?

Pspice is a powerful circuit simulator software tool that is widely used in the electronics industry. The software is built to simulate analog circuits and allows users to create high-quality designs quickly. The software is specifically designed to work with circuit boards and their components. Pspice was first introduced in the 1980s and has been continuously updated since. It is a reliable and robust circuit simulator software widely used in the electronics industry.

What is Ltspice?

Ltspice is a free, open-source circuit simulator used to simulate analog circuits. It was introduced by Linear Technology in 1998 and acquired by Analog Devices in 2020. It is widely used for designing and testing electronic circuits and analyzing the results. The software is user-friendly and provides a quick and easy way to evaluate the behavior of electronic circuits. It is available for both Windows and MAC operating systems.

Comparison between Pspice and Ltspice

Both Pspice and Ltspice are powerful tools used for the simulation of electronic circuits. They have many similar features, but there are specific differences between the two software tools. Below is a list of differences between the two programs:


Pspice is a paid tool, which means users have to subscribe to use it. The cost of the subscription varies depending on the required features and the duration of the license. On the other hand, Ltspice is free to use, and users do not have to pay any subscription fees.


Pspice has a user-friendly interface with many features and options, making it suitable for professional use. It is popular among engineers who work with complex circuits. Ltspice, on the other hand, has a relatively simple interface and is suitable for beginners or students who are learning about circuits.

Simulation speed:

Pspice simulation speed is relatively slower compared to Ltspice in terms of simulation of large circuits. Simulation speed is significant when working on extensive or complex circuits, as it can take a lot of time to generate results.


Pspice is a more powerful tool, and it can handle complex circuits with ease. It has many advanced features that help with circuit simulation, making it a more reliable tool for serious users. Ltspice is suitable for small and medium-sized circuits and is not recommended for larger circuits.


Both Pspice and Ltspice provide similar functionality. They allow users to simulate circuits and measure their performance. Pspice, however, provides some advanced features that Ltspice does not have, such as active filter design, PCB layout, mixed signal simulation, etc.

Frequently Asked Questions

1. Can I use Pspice and Ltspice on a MAC?

Yes, both Pspice and Ltspice are available for MAC OS, and users can download and install them on their MAC computers.

2. Can I import circuits from one software to another?

Yes, it is possible to export circuits from one software and import them into another software, but there could be some formatting issues.

3. Is Pspice better than Ltspice?

It depends on which features you require. Pspice is a more powerful tool than Ltspice and has many advanced features. However, if you only require basic circuit simulation, Ltspice may be the better choice as it is free to use.

4. Which of the two tools is easier to use?

Ltspice is much easier to use and has a more user-friendly interface, making it suitable for beginners. Pspice requires some level of expertise to utilize effectively as it is tailored towards advanced circuit simulation.


Pspice and Ltspice are both excellent circuit simulator software tools. While both programs have similarities, they also have unique features that distinguish them from one another. Pspice is more suitable for professional users and engineers who work with complex circuits, while Ltspice is more suitable for beginners or students. Ultimately, the choice between the two depends on the user’s specific requirements, budget, and level of expertise.
