You can also target legacy versions of ARTIQ; use Git to checkout older release branches. Note however that older releases of ARTIQ required different processes for developing and building, which you are broadly more likely to figure out by (also) consulting corresponding older versions of the manual.

If you are developing for Zynq, you will have noted that the ARTIQ-Zynq repository consists largely of firmware. The firmware for Zynq (NAR3) is more modern than that used for current mainline ARTIQ, and is intended to eventually replace it; for now it constitutes most of the difference between the two ARTIQ variants. The gateware for Zynq, on the other hand, is largely imported from mainline ARTIQ. If you intend to modify the gateware housed in the original ARTIQ repository, but build and test the results on a Zynq device, clone both repositories and set your ``PYTHONPATH`` after entering the ARTIQ-Zynq development shell: ::

Adding or removing new real-time hardware is a difference in *system configuration,* which must be specified at compilation time of gateware and firmware. For Kasli and Kasli-SoC, this is managed in the form of a JSON usually called the *system description* file. The device database generally provides that information to ARTIQ which can change from instance to instance ARTIQ is run, e.g., device names and aliases, network addresses, clock frequencies, and so on. The system configuration defines that information which is *not* permitted to change, e.g., what device is associated with which EEM port or RTIO channels. Insofar as data is duplicated between the two, the device database is obliged to agree with the system description, not the other way around.
|
||||
|
||||
If you obtain your hardware from M-Labs, you will always be provided with a ``device_db.py`` to match your system configuration, which you can edit as necessary to add remote devices, aliases, and so on. In the relatively unlikely case that you are writing a device database from scratch, the ``artiq_ddb_template`` utility can be used to generate a template device database directly from the JSON system description used to compile your gateware and firmware. This is the easiest way to ensure that details such as the allocation of RTIO channel numbers will be represented in the device database correctly. See also the corresponding entry in :ref:`Utilities <ddb-template-tool>`.

Getting started with the management system
|

==========================================
|

|

In practice, rather than managing experiments by executing ``artiq_run`` over and over, most use cases are better served by using the ARTIQ *management system.* This is the high-level part of ARTIQ, which can be used to schedule experiments, distribute and store the results, and manage devices and parameters. It possesses a detailed GUI and can be used on several machines concurrently, allowing them to coordinate with each other and with the specialized hardware over the network. As a result, multiple users on different machines can schedule experiments or retrieve results on the same ARTIQ system, potentially simultaneously.

A controller manager connects to the master and accesses the device database through it to determine what controllers need to be run. The local network address of the connection is used to filter for only those controllers allocated to the current node. Hostname resolution is supported. Changes to the device database are tracked and controllers will be stopped and started accordingly.
