![]() After dropping the tabular, the diagram dialog appears. Choose the tabular (list of values) diagram and place it on the data display page. From there, select a table and drag it to the work area. A new work area appears, and also the Explorer window changes to the diagram tab. Now save it and go to Simulation ->Simulate. Now, from simulations, place the DC simulation block the schematic should look like Figure 2. Select Insert->Wire label and click on the point between the two resistors and name it Vout (or anything you want). (Specifying a ground point is very essential in all circuit simulators.) Connect them using the wire (Ctrl+E) now place the ground symbol near the negative of the cell. Place two resistors from the lumped components and a DC source from sources. You can find the components via the components button on the left side of the Explorer window. Let’s start with a simple potential divider circuit. The workspace is where you draw your circuit. Once the project is created, you can see all the contents of the project in the Explorer window. Click the New button in the explorer window a dialogue box will appear asking for the project name supply one, and proceed. Launch QUCS and proceed to start a new project. There is also a component library that includes various standard components available in the market (bridges, diodes, varistors, LEDs, JFETs, MOSFETs, and so on). File containers (S-parameter datasets and SPICE netlists).Non-linear components (diodes, transistors, etc).Lumped components (R, L, C, amplifier, phase shifter, etc).The following categories of components are provided: The QUCS component library has almost all the components needed for most of the circuits, but as it is still in the development stages, some components might be missing. For circuit optimisation (minimisation of a cost function), ASCO is configured and run. For digital simulations (via VHDL), the program FreeHDL is used. Additionally, the GUI steers other EDA tools.The supported file formats as well as usage information can be found in the qucsconv man page. The command line conversion program tool is used by the GUI to import and export datasets, netlists and schematics from and to other CAD/EDA software.The attenuator synthesis application can be used to design various types of passive attenuators.The component library manager holds models for real-life devices (like transistors, diodes, bridges and opamps). ![]()
