Qucs
A command-line terminal circuit simulator that you can use both in the application or as a totally independent program
Qucs, also known as the Quite Universal Circuit Simulator, was developed as an affordable, open source, graphical, electronic circuit and loop simulator. The program supports all types of circuit simulation, such as DC, AC, S-parameters, harmonic balance analysis, noise analysis and so on. Simulation results can be viewed on the presentation page or program window.
Qucsator, the server part of the program, is a command-line simulator that manages a list of networks in a specific Qucs dataset I/O format. By default, it was created to work with the Qucs project, but it can also be used with other applications. The program supports exporting images of characters with Verilog-A files to C++ code, and supports direct communication with Verilog-HDL characters and VHDL trailers. The latest versions of Qucs have a GNU/Octave interface.
Qucs allows for comprehensive circuit simulation, covering a variety of parameters and analyses, at no cost.
- Verilog-HDL and Verilog-A syntax support in text documents;
- support of C++ code export;
- support of equations for Verilog-HDL and VHDL subchains;
- pre-compiled VHDL modules and libraries;
- support for all modern components;
- open source allows for the development of extensions;
- customizable and extensible interface;
- a built-in file converter;
- the ability to download additional interface languages.
PROS
Completely open-source, promoting transparency and customization.
User-friendly interface with detailed component library.
CONS
No real-time simulation feature.
The user interface can seem outdated and unappealing.

The Quite Universal Circuit Simulator (Qucs) is a software tool that enables users to design and analyze circuits, in various scenarios. It supports simulations for both circuits using VHDL and Verilog well as analog circuits. Qucs has its built in simulator called Qucsator. It also integrates with certain SPICE backends through the Qucs S fork. With a user interface, it provides a wide range of features such as schematic creation, analysis options like S parameter, AC, DC and transient analysis and various ways to represent data. Additionally it offers documentation, tutorials, technical descriptions and a library of components including lumped elements, nonlinear devices, digital components and transmission lines. All this feature makes Qucs highly useful for circuit design and analysis tasks. However one thing to note is that beginners might find it slightly challenging to get started due to its learning curve if they're not familiar, with circuit simulation software.
