Test for Continuous Integration using KiCad.
This repo contains two examples, one is the simplest situation and the other complicates things a little bit.
This is an example of how to test and generate documentation for a KiCad project automatically every time you commit a change to the schematic and/or PCB.
In this example we use a docker image containing KiCad, KiPlot and all the supporting tools.
The kicad_ci_test.kiplot.yaml configures KiPlot and says what's available.
The .github/workflows/test1.yml configures what GitHub makes.
In this file we:
- Instruct GitHub to run the tasks every time a change in the pertinent files is detected:
on:
push:
branches: [ master ]
paths:
- 'kicad_ci_test.sch'
- 'kicad_ci_test.kicad_pcb'
pull_request:
branches: [ master ]
paths:
- 'kicad_ci_test.sch'
- 'kicad_ci_test.kicad_pcb'
- Define actions for ERC, DRC, schematic documentation generation and PCB documentation generation.
- Each action takes the repo content as input using:
- uses: actions/checkout@v2
-
The actions are executed by KiPlot and stored in the Fabrication directory
-
The resulting files are stored as artifacts using:
- name: Recuperar resultados
uses: actions/upload-artifact@v1
with:
name: ERC_Output
path: Fabrication
For more information about the GitHub configuration read the Workflow syntax for GitHub Actions page.
This example is a little bit more complicated. First we have our project located in a sub directory called test_subdir and second we use an external library found in the kicad_ci_test_lib project.
The test_subdir/test_subdir.kiplot.yaml configures KiPlot and says what's available.
Note that this project has a four layers PCB so we generate gerbers for all of them. In the example file we refer to the ground plane as GND.Cu this is the name used in our PCB. Another option is to use the legacy KiPlot format: Inner.1, and this is what we do for the power plane (Inner.2 in this case).
The .github/workflows/test_subdir.yml configures what GitHub makes.
In this example we are putting all the real commands inside a Makefile and then invoking it like this:
- name: Run ERC
run: |
make -C test_subdir/ erc
This changes the workind directory to test_subdir/ and then makes the erc target, defined in the Makefile like this:
erc:
kiplot -d Fabrication -s run_drc,update_xml -i
Using a Makefile is just another way of doing things, you could put the commands in the GitHub worflow, but don't forget to change the working directory to test_subdir.
Another detail is how to checkout the submodules. One option is to use the submodules option of the checkout action. But for this we need the git command, which isn't part of the default kicad_auto docker image.
To solve this we use an auxiliar job called get_submodules, this job runs on the host operating system, which includes git, and does a checkout using:
- uses: actions/checkout@v2
with:
submodules: 'true'
So no we have the submodules. Note that if you need to get submodules inside submodules you'll need to use recursive instead of true.
Then this job creates an artifcat containig the submodule using:
- name: Store submodule
uses: actions/upload-artifact@v1
with:
name: Submodule
path: test_subdir/lib
So then other jobs can get the needed files using:
- name: Get submodule
uses: actions/download-artifact@v2
with:
name: Submodule
path: test_subdir/lib
In this way we get the submodules and we don't need to add git to kicad_auto.
