Development Highlight: December Edition, Features Coming to KiCad 7

The end of 2022 is here and quite some work has been accomplished on various parts of KiCad over the year.

We are all working to hopefully have a KiCad 7 release by the end of January 2023 but no promises!

This is a highlight of some (but not all) of the new features added since the last development highlight.

General Improvements

PCM automatic updates

qu1ck in a follow up to the adding the PCM in 6.0 has now introduced automatic update checking of already installed Plugins and Content in MR #1276.

Each time you launch KiCad, the plugin status is automatically queried in the background and displayed:

You can also disable the update checking behavior in Preferences.

Drag & Drop

lulu731 in MR #1244 added the drag and drop handles needed to various parts of KiCad that results in the following actions:

  • KiCad

    • .kicad_pro, .pro files trigger opening project

    • gerber and job files open Gerber Viewer

    • Eagle and Cadstar files trigger open project

  • Schematic Editor

    • Schematic gets appended

  • PCB Editor

    • Append board

  • Gerber Viewer

    • Open files

  • Drawing Sheet Editor

    • Open sheet

macOS Apple Sillycon support

Adam Wolf spent time in troubleshooting and identifying changes needed to get KiCad to build and package correctly as native Apple silicon processors (M1, M2, etc) bundles. Resulting in commit 98775afc and MR #376 kicad-mac-builder which took plenty of effort to decipher the correct process with Apple’s continuing effort to locking down the macOS ecosystem for better or for worse.

Command Line Interface

Mark Roszko in a slew of commits has added a new kicad-cli binary to the KiCad packages.

The separate kicad-cli binary was necessary to work around limitations on applications being both GUI and console on Windows at the executable level. Along with wxWidgets having a distinction between a GUI and console app for initializatin.

The kicad-cli brings all the necessary functions to automate export elements of schematic and pcb designs.

The currently avaiable commands are:

kicad-cli sch export bom
kicad-cli sch export netlist
kicad-cli sch export pdf
kicad-cli sch export svg
kicad-cli pcb export drill
kicad-cli pcb export dxf
kicad-cli pcb export gerber
kicad-cli pcb export pdf
kicad-cli pcb export pos
kicad-cli pcb export step
kicad-cli pcb export svg

You can use the -h argument to find out more about the command specific options.

These changes have also enabled the STEP export to work headless on Linux, unlike the original kicad2step binary.

We hope this is a useful mechanism for users to adopt. We do plan to introduce a GUI based jobs system in KiCad 8 but see this as a interim solution.

Schematic Editor Improvements

DNP fields

Seth Hillbrand in commit 524b129c added support for explicitly marking placed components in a schematic as "DNP" or Do Not Populate. The resulting components are also greyed out in the schematic and excluded from any KiCad generated placement files.

Simulation Model Editor

Mikolaj Wielgus in MR #1220 added a simulation model editor. This is a new dialog available as a "Simulation Model" button in the Symbol Properties of any schematic symbol. It allows you to configure simulation model parameters in a GUI rather than spice text inserted on schematic and the resulting configuration gets passed to the simulator as expected. You can do everything from configuring a symbol as "standard" spice models (resistors,caps,diodes,bjts), to assigning custom models in libraries (it will even load the library and let you select individual models contained within) and even let you customize the schematic pin to spice pin pin mapping.

Database Libraries

A long requested feature by certain users of KiCad has been the ability to link component selection to a database which is common in other schematic CAD tools. Jon Evans went ahead in MR #1282 to add connectivity to external databases via ODBC functionality across KiCad’s three main platforms.

The database library system allows creating a centralized database of symbol to footprint associations along with any metadata about your parts that can be shared across your schematics by you and others connected to the same database.

As a warning, KiCad’s intention is only to utilize a database as a source of information. It will never provide an interface to manage said information and it is up to user’s to integrate it with some other external tooling as part databases get very workflow specific very fast.

More information can be found here: and prelimary documentation is available here:

An ongoing forum discussion about the feature is also here:

Dynamic field columns in symbol chooser

As part of the database libraries introduction, Jon Evans in commit e294fe207 also introduced the ability to display custom fields in the symbol chooser.

Jeff Young and Roberto Fernandez Bautista in commit 840bcffefb7f9108b72eeba715536c4320fe9bee, commit 9b007ca4bf042f9915faeef0f87e4aefcc40b4d3 added support for hyperlinks inside schematics. This means you can place a text object on a schematic page and fill in a new Hyperlink property that makes the text object become clickable.

Supported hyperlinks are:

  • http://

  • https://

  • file://

  • #:<pagenumber> (where <pagenumber> is any valid schematic page)

PDF Improvements

PDF Bookmarks (Table of Contents)

Mark Roszko in commit 6f8205235 added support for populating the Bookmarks section (also known as the Table of Contents) of a PDF viewer with useful information.

Now in a schematic PDF generated by the Plot action in the Schematic Editor, you will find bookmarks populated with a list of sheets and links to symbols within the sheet. Clicking on items on the bookmark list will jump to the relevant page and location.

Component Info

Jeff Young in commit 8afc1db7a6 added the export of placed component info in schematics to the plotted PDF. This is a list of component field data displayed when the symbol is clicked in a PDF viewer. Unforunately, the functionality required for this to work is implemented per PDF spec but support across PDF viewers is not consistent. Adobe PDF Reader/Acrobat are known to display the list correctly.

Also added by Jeff Young in addition to Component Info and the implementation of schematic hyperlinks by Roberto, hyperlinks are also embedded into the PDF and interactable.

This includes:

  • Hyperlinks between pages

  • Hyperlinks to external URLs

  • Sheet symbols link to datasheets

PCB Editor Improvements

Various PCB Layout Tool Enhancements

Mike Williams has worked on various quality of life additions

Background bitmaps in the board and footprint editor

A sometimes requested feature by some users has been the ability to display an image in the background so that PCB traces can be copied easily from some original reference PCB being reverse engineered.

This is now possible since commit 3669cb46 and improved in commit 99f8b21ed to allow configuring a bitmap per board layer, making it easier for reverse engineering multi-layer boards.

Unroute Selected

Ever wanted to just completely unroute a footprint for reasons? commit ca0c9f12e0 has made this possible.

Auto-complete trace route

A nifty new utility added in commit 1a023f5dd that may be invaluable to power users with Hot keys, you can now draw traces partially and ask the PCB Editor to complete the trace the rest of the way to the nearest ratsnest end. It will stop and force you to manually route if it can’t find a route.

Attempt to Finish Selection

Related to the trace route completion feature, you can now select items and ask the PCB Editor to attempt to "auto route" traces between them. It will iterate each unrouted part of the item and attempt to connect it to the nearest rats nest.

Warning This is not intended to be an autorouter but instead a useful power tool to make connections quickly that sort of acts like one 😉

Search Panel

Mark Roszko added in commit f304e2d4f a new search panel

This panel in the PCB Editor enables typing query strings with wildcards and filtering out objects on the design while displaying all of the results in a list. The list can be clicked on to select objects on the editing canvas.

Properties Panel

Jon Evans took over work that was years ago started by Maciej Suminski to implement a unified properties system for editing within KiCad. The purpose of a unified properties system is to enable dynamically generated GUI interfaces that can be reused across multiple types of items rather than having to create dialogs for every possible object and it’s editing options.

The Properties Panel is now available in the PCB Editor as a result.

One immediate benefit is the Properties Panel allows multi-editing objects with similar properties, simply select the objects you want together and the potential options are displayed.

Future plans beyond 7.0 will be bringing the properties panel to the Schematic Editor and Drawing Sheets Editor.

Improved footprint spread and Pack & Move Footprint Tool

Have you ever drawn a large schematic and then finally opened the PCB board to begin a layout and find yourself staring at a jumbled mess of components to place? Well fear not!

dsa-t in MR #1325 introduced some improvements to the initial setup of a PCB layout.

First the algorithim that placed components on the PCB was improved to result in a more compact result.

Here is a before and after example of this change:

Screenshot showing a sample initial component placement under the old algorithim

Secondly, a powerful new tool was added that let’s you select a logical portion of your schematic yourself in the Schematic Editor and with a new right click menu option in the PCB Editor, you can now "Pack and Move" the selected components as one compacted group rather than having to jump around all over the PCB Editor to locate and drag components.

STEP Exporter Changes

Mark Roszko in a series of commits overhauled the STEP exporter to use the same PCB parsing engine as the rest of KiCad. It’s independence from the main KiCad codebase resulted in various bugs over time and became hard to maintain as the main PCB format evolved.

This change now brings the addition relative 3d model paths to the footprint. Simply start the paths with the expected ./ or ../ and the 3D viewer and STEP exporter will attempt to find the model relative to the footprint file. This change should allow better portability of footprint libraries.

Finally, "3D Path Aliases" were removed from KiCad. These were an independent system from the "Environment Variable" system also used for paths. It had it’s own file format and usage syntax which both introduced unexpected bugs. Unifying the system makes the usage of Environment Variables standard throughout KiCad. "3D Path Aliases" will be automigrated to an Environment variable on launch. However, the alias may get renamed if the alias had characters beyond uppercase A-Z,0-9 and underscores due to the limitations of Environment Variables across platforms.

End of Year Wrap Recap

The KiCad developers held a recap livestream on December 17th, 2022. It covers a few more features and discussions on the future of KiCad.

Development Highlight: April Update

It has been two full months since the February development highlight went over the changes in January.

Here’s a fresh update on new features and changes that have happened to 6.99 nightlies. This isn’t a complete list as many changes come in smaller incremental changes that are hard to talk about.

Development Highlight: February Update

It’s only been a month since the 6.0 release and work is well under way for the future 7.0 release with many features and improvements to come over the course of the year.

As a friendly reminder, nightlies are currently unstable, you can use them for testing and experimenting but we make no guarantees on the stability right now. Use them at your own risk, keep backups, especially if you are upgrading nightly versions.
