KiCad EDA v7.0.10
KiCad EDA v7.0.10 A Cross Platform and Open Source Electronics Design Automation Suite Schematic Capture KiCad's Schematic Editor supports everything from the most basic schematic to a complex hierarchical design with hundreds of sheets. Create your own custom symbols or use some of the thousands found in the official KiCad library. Verify your design with integrated SPICE simulator and electrical rules checker. PCB Layout KiCad's PCB Editor is approachable enough to make your first PCB design easy, and powerful enough for complex modern designs. A powerful interactive router and improved visualization and selection tools make layout tasks easier than ever. 3D Viewer KiCad's 3D Viewer allows easy inspection of your PCB to check mechanical fit and to preview your finished product. A built-in raytracer with customizable lighting can create realistic images to show off your work. About KiCad KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and macOS and is licensed under GNU GPL v3. Mission Statement The goal of the KiCad project is to provide the best possible cross platform electronics design application for professional electronics designers. Every effort is made to hide the complexity of advanced design features so that KiCad remains approachable by new and inexperienced users, but when determining the direction of the project and the priority of new features, the needs of professional users take precedence. Project Governance The KiCad project is governed by a technical committee made up of the members of the lead development team. Most decisions are made by a consensus of the technical committee. When a consensus cannot be reached the final decision is made by the project leader. History KiCad was first released in 1992 by its original author, Jean-Pierre Charras. It has been in continual ...

Quite Universal Circuit Simulator 0.0.19
Quite Universal Circuit Simulator 0.0.19 Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported. Features schematic capture analog and digital simulations data visualization What's Qucs? Qucs stands for Quite Universal Circuit Simulator. So far Qucs is not yet finished, but it is already packed with features. Take a look at the screenshots to get a feel for what it can do. 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. After that simulation has finished you can view the simulation results on a presentation page or window. Qucs, briefly for Quite Universal Circuit Simulator, is a circuit simulator with graphical user interface (GUI). The GUI is based on Qt® by Digia®. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc. Qucsator, the simulation backend, is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset. It has been programmed for usage in the Qucs project but may also be used by other applications. The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available. Qucs can also import existing SPICE models for use in your simulations. While Qucs is well developed, we still strive to improve the ...
