KiPlot
KiPlot is a program which helps you to plot your KiCad PCBs to output formats easily, repeatable, and most of all, scriptably. This means you can use a Makefile to export your KiCad PCBs just as needed.
For example, it's common that you might want for each board rev:
- Check ERC/DRC one last time (using KiCad Automation Scripts)
- Gerbers, drills and drill maps for a fab in their favourite format
- Fab docs for the assembler
- Pick and place files
- PCB 3D model in STEP format
You want to do this in a one-touch way, and make sure everything you need to do so it securely saved in version control, not on the back of an old datasheet.
KiPlot lets you do this.
As a side effect of providing a scriptable plot driver for KiCad, KiPlot also allows functional testing of KiCad plot functions, which would otherwise be somewhat unwieldy to write.
The configuration file
Kiplot uses a configuration file where you can specify what outputs to generate. By default you'll generate all of them, but you can specify which ones from the command line.
The configuration file should be named .kiplot.yaml. The format used is YAML. This is basically a text file with some structure. This file can be compressed using gzip file format.
The header
All configuration files must start with:
kiplot:
version: 1
This tells to Kiplot that this file is using version 1 of the format.
The preflight section
This section is used to specify tasks that will executed before generating any output. The available tasks are:
run_ercTo run the ERC (Electrical Rules Check). To ensure the schematic is electrically correct.run_drcTo run the DRC (Distance Rules Check). To ensure we have a valid PCB.update_xmlTo update the XML version of the BoM (Bill of Materials). To ensure our generated BoM is up to date.check_zone_fillsZones are filled before doing any operation involving PCB layers.
The run_drc command has the following option:
ignore_unconnectedIgnores the unconnected nets. Useful if you didn't finish the routing.
Here is an example of a preflight section:
preflight:
run_erc: true
update_xml: true
run_drc: true
check_zone_fills: true
ignore_unconnected: false
Filtering DRC/ERC errors
Sometimes KiCad reports DRC or ERC errors that you can't get rid off. This could be just because you are part of a team including lazzy people that doesn't want to take the extra effort to solve some errors that aren't in fact errors, just small violations made on purpose. In this case you could exclude some known errors.
For this you must declare filters entry in the preflight section. Then you can add as many filter entries as you want. Each filter entry has an optional description and defines to which error type is applied (number) and a regular expression that the error must match to be ignored (regex). Like this:
filters:
- filter: 'Optional filter description'
number: Numeric_error_type
regex: 'Expression to match'
Here is an example, suppose you are getting the following errors:
** Found 1 DRC errors **
ErrType(4): Track too close to pad
@(177.185 mm, 78.315 mm): Track 1.000 mm [Net-(C3-Pad1)] on F.Cu, length: 1.591 mm
@(177.185 mm, 80.715 mm): Pad 2 of C3 on F.Cu and others
** Found 1 unconnected pads **
ErrType(2): Unconnected items
@(177.185 mm, 73.965 mm): Pad 2 of C4 on F.Cu and others
@(177.185 mm, 80.715 mm): Pad 2 of C3 on F.Cu and others
And you want to ignore them. You can add the following filters:
filters:
- filter: 'Ignore C3 pad 2 too close to anything'
number: 4
regex: 'Pad 2 of C3'
- filter: 'Ignore unconnected pad 2 of C4'
number: 2
regex: 'Pad 2 of C4'
If you need to match text from two different lines in the error message try using (?s)TEXT(.*)TEXT_IN_OTHER_LINE.
If you have two or more different options for a text to match try using (OPTION1|OPTION2).
A complete Python regular expressions explanation is out the scope of this manual. For a complete reference consult the Python manual.
Important note: this will create a file named kiplot_errors.filter in the output directory.
The outputs section
In this section you put all the things that you want to generate. This section contains one or more outputs. Each output contain the following data:
namea name so you can easily identify it.commenta short description of this output.typeselects which type of output will be generated. Examples are gerbers, drill files and pick & place filesdiris the directory where this output will be stored.optionscontains one or more options to configure this output.layersa list of layers used for this output. Not all outputs needs this subsection.
Important note about the layers: In the original kiplot (from John Beard) the name of the inner layers was Inner.N where N is the number of the layer, i.e. Inner.1 is the first inner layer. This format is supported for compatibility. Note that this generated a lot of confusion because the default KiCad name for the first inner layer is In1.Cu. People filled issues and submitted pull-requests to fix it, thinking that inner layers weren't supported. Currently KiCad allows renaming these layers, so this version of kiplot supports the name used in KiCad. Just use the same name you see in the user interface.

Using KiPlot
If you need a template for the configuration file try:
kiplot --example
This will generate a file named example.kiplot.yaml containing all the available options and comments about them.
You can use it to create your own configuration file.
If you want to use the layers of a particular PCB in the example use:
kiplot -b PCB_FILE --example
And if you want to use the same options selected in the plot dialog use:
kiplot -b PCB_FILE -p --example
If the current directory contains only one PCB file and only one configuration file (named *.kiplot.yaml)
you can just call kiplot. No arguments needed. The tool will figure out which files to use.
If more than one file is found in the current directory kiplot will use the first found and issue a
warning. If you need to use other file just tell it explicitly:
kiplot -b PCB_FILE.kicad_pcb -c CONFIG.kiplot.yaml
A simple target can be added to your makefile, so you can just run
make pcb_files or integrate into your current build process.
pcb_files:
kiplot -b $(PCB) -c $(KIPLOT_CFG)
If you need to supress messages use --quiet or -q and if you need to get more informatio about
what's going on use --verbose or -v.
If you want to generate only some of the outputs use:
kiplot OUTPUT_1 OUTPUT_2
If you want to generate all outputs with some exceptions use:
kiplot --invert-sel OUTPUT_1 OUTPUT_2
If you want to skip the DRC and ERC use:
kiplot --skip-pre run_erc,run_drc
If you want to skip all the preflight tasks use:
kiplot --skip-pre all
All outputs are generated using the current directory as base. If you want to use another directory as base use:
kiplot --out-dir OTHER_PLACE
If you want to list the available outputs defined in the configuration file use:
kiplot --list

- For interactive BoM install InteractiveHtmlBom
Installation on Ubuntu/Debian:
Get the Debian package from the releases section and run:

Installation on other targets
- Install KiCad 5.x
- Install Python 3.5 or newer
- Install the Python Yaml module

Using for CI/CD
When using a GitHub or GitLab repo you can use KiPlot to generate all the needed stuff each time you commit a change to the schematic and/or PCB file.
Examples of how to do it can be found here for GitHub and here for GitLab.
In order to run KiPlot on these environments you need a lot of software installed. The usual mechanism to achieve this is using docker. Docker images containing KiPlot, all the supporting scripts and a corresponding KiCad can be found at Docker Hub as setsoft/kicad_auto:latest. This image is based on setsoft/kicad_debian:latest, containing KiCad on Debian GNU/Linux.
For more information about the docker images visit kicad_debian and kicad_auto.
