Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

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

Ope! Hold on, Speedy.
You gotta read this before you download below:

There are no ads, no fake download buttons and no crapware here.
This website has lived for 18 years solely through donations.
You can download without donating but we use the "Honor System"
here in the Ozarks. If your momma raised you to be honorable,
make your donation to keep things running.
Your momma would be so proud!

Thank you! -Randy & Deanna (The Older Geeks)
