Tests

To run the hardware tests, you need Modelsim (the testbenches proper are in tb/), and Julia to create the test data (in the reference implementation directory ref/).

To run the driver and software tests, you need the docker container as described below:

Build

First, build the docker container containing the build tools. This will take a while, as it downloads Quartus, SoC EDS, and cross compilation tools. You will need more than 15 GiB free space.

cd docker
docker build . -t quartus-cyclonev-soceds

Then, start the build proper. This will take a while, depending on the steps that have completed/are not yet complete:

  • Compile the hardware (~10 minutes)
  • Compile uboot (~5 minutes)
  • Compile the kernel (~10 minutes)
  • Download the Ubuntu rootfs
  • Build the SD card image

This needs to run in a privileged container to use the loopback device to create the SD card image.

Run this from the root of the repository:

docker run -it --privileged --net=host -v $PWD:/src -w /src quartus-cyclonev-soceds ./build.sh

The resulting SD card will be in sw/sdcard.img.`
