KiCad 6.0: Features, Improvements, and Bug Fixes



How to Download and Install KiCad 6.0 - A Complete Guide




If you are looking for a free and open-source software suite for electronic design automation (EDA), you should consider KiCad. KiCad is a powerful tool that can help you create electronic circuit schematics, printed circuit boards (PCBs), and associated part descriptions. In this article, we will show you how to download and install KiCad 6.0, the latest major version release of KiCad, on your computer. We will also highlight some of the new features and improvements that make this release a substantial upgrade over the previous versions. Finally, we will point you to some resources and tutorials that can help you get started with using KiCad.


What is KiCad and why use it?




KiCad is an open-source software suite for electronic design automation (EDA)




KiCad is developed by a volunteer team of software and electrical engineers around the world with a mission of creating free and open-source electronics design software suitable for professional designers. KiCad has been in continual development since 1992 and is now managed by the KiCad Development Team. The name of KiCad comes from the first letters of a company of Jean-Pierre Charras' friend "Ki" being combined with "Cad". But it now has no meaning other than being the name of the software suite.

KiCad features an integrated environment for schematic capture, PCB layout, manufacturing file viewing, SPICE simulation, and engineering calculation




KiCad supports an integrated design workflow in which a schematic and corresponding PCB are designed together, as well as standalone workflows for special uses. KiCad also includes several utilities to help with circuit and PCB design, including a PCB calculator for determining electrical properties of circuit structures, a Gerber viewer for inspecting manufacturing files, a 3D viewer for visualizing the finished PCB, and an integrated SPICE simulator for inspect ing the behavior of your circuit.


KiCad supports up to 32 copper layers and is suitable for creating designs of all complexities




KiCad can handle PCB designs ranging from simple single-sided boards to complex multi-layer boards with up to 32 copper layers. KiCad also supports flexible and rigid-flex PCBs, as well as high-speed and high-density interconnect (HDI) PCBs. KiCad has no artificial limitations on board size, number of components, or number of nets. You can create designs as large and complex as you need with KiCad.

What's new in KiCad 6.0?




KiCad 6.0 features a refreshed user interface designed to reduce the barriers of entry for new users and ease friction when switching between KiCad and other design software




KiCad 6.0 introduces a new user interface theme that is more modern, consistent, and intuitive. The new theme uses a dark background with bright colors for better contrast and visibility. The new theme also uses icons that are more recognizable and familiar to users of other design software, such as Eagle, Altium, or Fusion 360. The new theme also improves the usability and accessibility of KiCad by providing better feedback, tooltips, keyboard navigation, and context menus.


KiCad's schematic editor has received its biggest overhaul ever for version 6.0 with dozens of new features to empower your design




KiCad's schematic editor, Eeschema, has been redesigned from the ground up for version 6.0 with many new features and improvements that make it easier and faster to create and edit your schematics. Some of the highlights are:


  • New symbol library format: KiCad 6.0 introduces a new symbol library format that is more flexible, robust, and portable. The new format allows you to store multiple symbols in a single file, use hierarchical symbols with nested sub-symbols, use custom fields and properties for symbols, and use relative paths for symbol libraries.



  • New symbol editor: KiCad 6.0 introduces a new symbol editor that allows you to create and edit your own symbols with ease. The new editor supports advanced features such as pin groups, pin stacking, pin swapping, pin numbering schemes, symbol templates, symbol inheritance, symbol variants, symbol previews, and more.



  • New bus system: KiCad 6.0 introduces a new bus system that allows you to create and manage complex bus structures with ease. The new system supports bus labels, bus wires, bus entries, bus ports, bus groups, bus aliases, bus definitions, bus connections, and more.



  • New annotation system: KiCad 6.0 introduces a new annotation system that allows you to assign reference designators to your components automatically or manually with ease. The new system supports annotation by sheet or by project, annotation by position or by value, annotation by increment or by offset, annotation by prefix or by suffix, annotation by filter or by scope, annotation by lock or by unlock, annotation by renumber or by reset, annotation by update or by back-annotate, and more.



  • New cross-probing system: KiCad 6.0 introduces a new cross-probing system that allows you to synchronize your schematic and PCB views with ease. The new system supports cross-probing between Eeschema and Pcbnew by highlighting the corresponding components, nets, pads, and tracks. The new system also supports cross-probing between Eeschema and Ngspice by highlighting the corresponding nodes, voltages, currents, and waveforms.



  • New graphical objects: KiCad 6.0 introduces new graphical objects that allow you to add more visual elements to your schematics. The new objects include polygons, arcs, circles, ellipses, splines, bitmaps, and text boxes.



  • New schematic format: KiCad 6.0 introduces a new schematic format that is more human-readable, robust, and portable. The new format uses S-expressions to store the schematic data in a hierarchical and structured way. The new format also supports version control systems and diff tools.



KiCad's PCB editor has improved visualization and selection tools and a powerful interactive router with built-in signal integrity tools
