The preferred way of installing ARTIQ is through the use of the conda package manager. The conda package contains pre-built binaries that you can directly flash to your board.
NIST users on Linux need to pay close attention to their
The sledgehammer called
secureconfig leaves you (and root) with umask 027 and files created by root (for example through
sudo make install) inaccessible to you.
The usual umask is 022.
Conda packages are supported for Linux (64-bit) and Windows (64-bit). Users of other operating systems (32-bit Linux or Windows, BSD, OSX ...) should and can install from source.
Installing Anaconda or Miniconda¶
You can either install Anaconda (choose Python 3.5) from https://store.continuum.io/cshop/anaconda/ or install the more minimalistic Miniconda (choose Python 3.5) from http://conda.pydata.org/miniconda.html
After installing either Anaconda or Miniconda, open a new terminal (also known as command line, console, or shell and denoted here as lines starting with
$) and verify the following command works:
conda should print the help of the
conda command .
Installing the ARTIQ packages¶
On a system with a pre-existing conda installation, it is recommended to update conda to the latest version prior to installing ARTIQ.
First add the conda-forge repository containing ARTIQ dependencies to your conda configuration:
$ conda config --prepend channels http://conda.anaconda.org/conda-forge/label/main
Then add the M-Labs
main Anaconda package repository containing stable releases and release candidates:
$ conda config --prepend channels http://conda.anaconda.org/m-labs/label/main
To use the development versions of ARTIQ, also add the
dev label (http://conda.anaconda.org/m-labs/label/dev).
Development versions are built for every change and contain more features, but are not as well-tested and are more likely to contain more bugs or inconsistencies than the releases in the
Then prepare to create a new conda environment with the ARTIQ package and the matching binaries for your hardware:
choose a suitable name for the environment, for example
artiq-main if you intend to track the main label,
artiq-3 for the 3.x release series, or
artiq-2016-04-01 if you consider the environment a snapshot of ARTIQ on 2016-04-01.
Choose the package containing the binaries for your hardware:
artiq-kc705-nist_clockfor the KC705 board with the NIST “clock” FMC backplane and AD9914 DDS chips.
artiq-kc705-nist_qc2for the KC705 board with the NIST QC2 FMC backplane and AD9914 DDS chips.
Conda will create the environment, automatically resolve, download, and install the necessary dependencies and install the packages you select:
$ conda create -n artiq-main artiq-kc705-nist_clock
After the installation, activate the newly created environment by name. On Unix:
$ source activate artiq-main
$ activate artiq-main
This activation has to be performed in every new shell you open to make the ARTIQ tools from that environment available.
Some ARTIQ examples also require matplotlib and numba, and they must be installed manually for running those examples. They are available in conda.
When upgrading ARTIQ or when testing different versions it is recommended that new environments are created instead of upgrading the packages in existing environments. Keep previous environments around until you are certain that they are not needed anymore and a new environment is known to work correctly. You can create a new conda environment specifically to test a certain version of ARTIQ:
$ conda create -n artiq-test-1.0rc2 artiq-kc705-nist_clock=1.0rc2
Switching between conda environments using
$ source deactivate artiq-1.0rc2 and
$ source activate artiq-1.0rc1 is the recommended way to roll back to previous versions of ARTIQ.
You can list the environments you have created using:
$ conda env list
See also the conda documentation for managing environments.
Preparing the core device FPGA board¶
You now need to write three binary images onto the FPGA board:
- The FPGA gateware bitstream
- The BIOS
- The ARTIQ runtime
They are all shipped in the conda packages, along with the required flash proxy gateware bitstreams.
OpenOCD can be used to write the binary images into the core device FPGA board’s flash memory.
artiq-dev conda packages install
openocd automatically but it can also be installed explicitly using conda on both Linux and Windows:
$ conda install openocd
Some additional steps are necessary to ensure that OpenOCD can communicate with the FPGA board.
On Linux, first ensure that the current user belongs to the
plugdev group. If it does not, run
sudo adduser $USER plugdev and relogin. Afterwards:
$ wget https://raw.githubusercontent.com/ntfreak/openocd/406f4d1c68330e3bf8d9db4e402fd8802a5c79e2/contrib/99-openocd.rules $ sudo cp 99-openocd.rules /etc/udev/rules.d $ sudo adduser $USER plugdev $ sudo udevadm trigger
On Windows, a third-party tool, Zadig, is necessary. Use it as follows:
- Make sure the FPGA board’s JTAG USB port is connected to your computer.
- Activate Options → List All Devices.
- Select the “Digilent Adept USB Device (Interface 0)” device from the drop-down list.
- Select WinUSB from the spinner list.
- Click “Install Driver” or “Replace Driver”.
You may need to repeat these steps every time you plug the FPGA board into a port where it has not been plugged into previously on the same system.
Flashing the core device¶
Then, you can flash the board:
For the KC705 board (selecting the appropriate hardware peripheral):
$ artiq_flash -t kc705 -m [nist_clock/nist_qc2]
The SW13 switches also need to be set to 00001.
The next step is to flash the MAC and IP addresses to the board. See those instructions.
Configuring the core device¶
This should be done after either installation method (conda or source).
Set the MAC and IP address in the core device configuration flash storage (see above for the
artiq_flashthat may be required):
$ artiq_mkfs flash_storage.img -s mac xx:xx:xx:xx:xx:xx -s ip xx.xx.xx.xx $ artiq_flash -t [board] -m [adapter] -f flash_storage.img proxy storage start
(optional) Flash the idle kernel
The idle kernel is the kernel (some piece of code running on the core device) which the core device runs whenever it is not connected to a PC via Ethernet. This kernel is therefore stored in the core device configuration flash storage. To flash the idle kernel:
- Compile the idle experiment:
The idle experiment’s
run()method must be a kernel: it must be decorated with the
@kerneldecorator (see next topic for more information about kernels).
Since the core device is not connected to the PC, RPCs (calling Python code running on the PC from the kernel) are forbidden in the idle experiment.$ artiq_compile idle.py
Write it into the core device configuration flash storage:$ artiq_coreconfig write -f idle_kernel idle.elf
You can find more information about how to use the
artiq_coreconfig utility on the Utilities page.
- (optional) Flash the startup kernel
The startup kernel is executed once when the core device powers up. It should initialize DDSes, set up TTL directions, etc. Proceed as with the idle kernel, but using the
startup_kernel key in
- (optional) Select the startup clock
The core device may use either an external clock signal or its internal clock. This clock can be switched dynamically after the PC is connected using the
external_clock parameter of the core device driver; however, one may want to select the clock at power-up so that it is used for the startup and idle kernels. Use one of these commands:
$ artiq_coreconfig write -s startup_clock i # internal clock (default) $ artiq_coreconfig write -s startup_clock e # external clock
