To save an open document click on the save button (or use the main menu: File Save). The left tabular bar is then switched to Content, and the content of the currently opened project displayed. On creation a new project is immediately opened and it’s name displayed on the Qucs window title bar. Every file belonging to this new project is saved within the QucsHelpFig_prj directory. In the example shown in Figure 3 this is called QucsHelpFig_prj.
Qucs then creates a project directory in the ~/.qucs directory. Enter the name of a Qucs project in the box provided, for example enter QucsHelpFig and click on the OK button. This action causes a Qucs GUI dialogue to open. To enter a new project left click on the New button located on the right above window (1). However note, when Qucs is launched for the first time the Projects list is empty.įigure 3 - Qucs main window with working areas labelled After running Qucs, the Projects tab is activated. On the left hand side of the Qucs main window is a third area labelled (1) whose content depends on the status of Projects (2), Content (3), Components (4) or Libraries. Clicking, with the left hand mouse button on any of the entries in the tabular bar labelled (5) allows users to quickly switch between the currently open documents. This window is used for displaying schematics, numerical and algebraic model and circuit design data, numerical output data, and signal waveforms and numerial data visualised as graphs, see Figure 3.
On launching Qucs a working area labelled (6) appears at the centre of the GUI.
Complete, with appropriate entries for your Qucs installation, the Settings, Source Code Editor, File Types and Locations menus. Clicking on Application Settings causes the EditQucsProperties window to be displayed, see Figure 2.
This is done from the File Application Settings menu.
After Qucs has been launched, the software displays a Graphical User Interface window (GUI) similar, or the same, to the one shown in Figure 1.īefore using Qucs it is advisable to set the program application settings. qucs directory or in one of it’s sub-directories. All files involved in Qucs simulations are saved in the. When Qucs is launched for the first time, it creates a directory called. This section of the Qucs-Help document introduces readers to the basic steps involved in Qucs analogue circuit simulation. Qucs is a scientific/engineering software package for analogue and digital circuit simulation, including linear and non-linear DC analysis, small signal S parameter circuit analysis, time domain transient analysis and VHDL/Verilog digital circuit simulation. Getting Started with Qucs Analogue Circuit Simulation ¶ The distributed tarballs can be downloaded from. The source code is available as distribution tarballs and clones of the Git repository. : are branches with a good reason to be in the main repository (ease collaboration, use CI facilities).release-x.y.z: are temporary branches being stabilized for a release.This should be the base branch of Pull-Requests or contributions. develop: contains the latest developments or unstable.master: contains the latest stable release.Under this strategy the following branches can be found in the repository: Resourcesīranching strategy for the Git repositoryĪfter release 0.0.18 the project started to use the Git flow strategy for branching. After that simulation has finished you can view the simulation results on a presentation page or window.
Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit.
