Qucs v0.0.19
Qucs v0.0.19 👉 Open-source circuit simulator for analog and digital electronics design and analysis. Qucs (Quite Universal Circuit Simulator) is an open-source electronics circuit simulator designed to perform circuit simulation using graphical schematic capture and a powerful simulation backend. It allows users to design circuits visually and analyze them with a wide range of simulation types including DC, AC, S-parameter, transient, harmonic balance, and noise analysis. Qucs features an intuitive graphical user interface for schematic entry, simulation setup, and result visualization. Simulation results can be displayed in various forms such as Cartesian, polar, Smith charts, tabular data, and timing diagrams. The software supports analog and digital components, RF simulation capabilities, and equation-defined devices, making it suitable for students, hobbyists, and engineers. Qucs uses SPICE-compatible simulation engines and supports netlist-based simulation, giving users flexibility in circuit analysis. It also includes optimization tools, parameter sweeps, and support for user-defined components and models. Features: • Graphical schematic capture with component library • DC, AC, transient, S-parameter, noise, and harmonic balance simulations • RF circuit simulation capabilities • Parameter sweeps and optimization tools • Equation-defined devices and custom models • SPICE-compatible netlist support • Data visualization including Cartesian, polar, and Smith charts • Tabular and timing diagram result display • Subcircuit and hierarchical design support • Cross-platform open-source application Supported operating systems: • Windows (XP, Vista, 7, 8, 10) • Linux • FreeBSD • macOS Supported languages: • English This download is for the Windows version (very bottom of page).
