Highlights:
* Support for Kasli-SoC, a new EEM carrier based on a Zynq SoC, enabling much faster kernel execution.
* New hardware support:
- Kasli-SoC, a new EEM carrier based on a Zynq SoC, enabling much faster kernel execution.
- HVAMP_8CH 8 channel HV amplifier for Fastino / Zotinos
- Almazny mezzanine board for Mirny
* Softcore targets now use the RISC-V architecture (VexRiscv) instead of OR1K (mor1kx).
* WRPLL
* Compiler:
- Supports kernel decorator with paths.
- Faster compilation for large arrays/lists.
* Faster compilation for large arrays/lists.
* Phaser:
- Improved documentation
- Expose the DAC coarse mixer and ``sif_sync``
- Exposes upconverter calibration and enabling/disabling of upconverter LO & RF outputs.
- Add helpers to align Phaser updates to the RTIO timeline (``get_next_frame_mu()``)
* ``get()``, ``get_mu()``, ``get_att()``, and ``get_att_mu()`` functions added for AD9910 and AD9912
* New hardware support:
- HVAMP_8CH 8 channel HV amplifier for Fastino / Zotino
* On Kasli, the number of FIFO lanes in the scalable events dispatcher (SED) can now be configured in
the JSON hardware description file.
* ``artiq_ddb_template`` generates edge-counter keys that start with the key of the corresponding
TTL device (e.g. ``"ttl_0_counter"`` for the edge counter on TTL device``"ttl_0"``)
* ``artiq_master`` now has an ``--experiment-subdir`` option to scan only a subdirectory of the
repository when building the list of experiments.
* The configuration entry ``rtio_clock`` supports multiple clocking settings, deprecating the usage
of compile-time options.
* DRTIO: added support for 100MHz clock.
* Previously detected RTIO async errors are reported to the host after each kernel terminates and a
warning is logged. The warning is additional to the one already printed in the core device log upon
detection of the error.
* HDF5 options can now be passed when creating datasets with ``set_dataset``. This allows
in particular to use transparent compression filters as follows:
``set_dataset(name, value, hdf5_options={"compression": "gzip"})``.
* Removed worker DB warning for writing a dataset that is also in the archive
Breaking changes:
* Due to the new RISC-V CPU, the device database entry for the core device needs to be updated.
The ``target`` parameter needs to be set to ``rv32ima`` for Kasli 1.x and to ``rv32g`` for all
other boards. Freshly generated device database templates already contain this update.
* Updated Phaser-Upconverter default frequency 2.875 GHz. The new default uses the target PFD
frequency of the hardware design.
* ``Phaser.init()`` now disables all Kasli-oscillators. This avoids full power RF output being
@ -38,6 +49,11 @@ Breaking changes:
* Phaser: fixed coarse mixer frequency configuration
* Mirny: Added extra delays in ``ADF5356.sync()``. This avoids the need of an extra delay before
calling `ADF5356.init()`.
* DRTIO: Changed message alignment from 32-bits to 64-bits.
* The deprecated ``set_dataset(..., save=...)`` is no longer supported.
* The internal dataset representation was changed to support tracking HDF5 options like e.g.
a compression method. This requires changes to code reading the dataset persistence file
(``dataset_db.pyon``) and to custom applets.

@ -70,8 +86,11 @@ Highlights:
- Improved performance for kernel RPC involving list and array.
* Coredevice SI to mu conversions now always return valid codes, or raise a ``ValueError``.
* Zotino now exposes ``voltage_to_mu()``
* ``ad9910``: The maximum amplitude scale factor is now ``0x3fff`` (was ``0x3ffe``
before).
* ``ad9910``:
- The maximum amplitude scale factor is now ``0x3fff`` (was ``0x3ffe`` before).
- The default single-tone profile is now 7 (was 0).
- Added option to ``set_mu()`` that affects the ASF, FTW and POW registers
instead of the single-tone profile register.
* Mirny now supports HW revision independent, human readable ``clk_sel`` parameters:
"XO", "SMA", and "MMCX". Passing an integer is backwards compatible.
* Dashboard:
@ -104,9 +123,13 @@ Breaking changes:
* ``quamash`` has been replaced with ``qasync``.
* Protocols are updated to use device endian.
* Analyzer dump format includes a byte for device endianness.
* To support variable numbers of Urukul cards in the future, the
``artiq.coredevice.suservo.SUServo`` constructor now accepts two device name lists,
``cpld_devices`` and ``dds_devices``, rather than four individual arguments.
* Experiment classes with underscore-prefixed names are now ignored when ``artiq_client``
determines which experiment to submit (consistent with ``artiq_run``).

IIR loading starts once the ADC presents its data, the DDSes are updated
once the IIR processing is over. These are the only blocking processes.
IIR shifting happens in parallel to writing to the DDSes and ADC conversions
take place while the IIR filter is processing or the DDSes are being
written to, depending on the cycle duration (given by whichever module
takes the longest).

@ -5,24 +5,19 @@ Developing ARTIQ
This section is only for software or FPGA developers who want to modify ARTIQ. The steps described here are not required if you simply want to run experiments with ARTIQ. If you purchased a system from M-Labs or QUARTIQ, we normally provide board binaries for you.
The easiest way to obtain an ARTIQ development environment is via the Nix package manager on Linux. The Nix system is used on the `M-Labs Hydra server <https://nixbld.m-labs.hk/>`_ to build ARTIQ and its dependencies continuously; it ensures that all build instructions are up-to-date and allows binary packages to be used on developers' machines, in particular for large tools such as the Rust compiler.
ARTIQ itself does not depend on Nix, and it is also possible to compile everything from source (look into the ``.nix`` files from the ``nix-scripts`` repository and run the commands manually) - but Nix makes the process a lot easier.

* Download Vivado from Xilinx and install it (by running the official installer in a FHS chroot environment if using NixOS). If you do not want to write to ``/opt``, you can install it in a folder of your home directory. The "appropriate" Vivado version to use for building the bitstream can vary. Some versions contain bugs that lead to hidden or visible failures, others work fine. Refer to `Hydra <https://nixbld.m-labs.hk/>`_ and/or the ``vivado.nix`` file from the ``nix-scripts`` repository in order to determine which version is used at M-Labs. If the Vivado GUI installer crashes, you may be able to work around the problem by running it in unattended mode with a command such as ``./xsetup -a XilinxEULA,3rdPartyEULA,WebTalkTerms -b Install -e 'Vitis Unified Software Platform' -l /opt/Xilinx/``.
* Download Vivado from Xilinx and install it (by running the official installer in a FHS chroot environment if using NixOS; the ARTIQ flake provides such an environment).

* During the Vivado installation, uncheck ``Install cable drivers`` (they are not required as we use better and open source alternatives).
* Install the `Nix package manager <http://nixos.org/nix/>`_ and Git (e.g. ``$ nix-shell -p git``).
* Set up the M-Labs binary substituter (:ref:`same procedure as the user section <installing-nix-users>`) to allow binaries to be downloaded. Otherwise, tools such as LLVM and the Rust compiler will be compiled on your machine, which uses a lot of CPU time, memory, and disk space.
* Clone the repositories https://github.com/m-labs/artiq and https://git.m-labs.hk/m-labs/nix-scripts.
* If you did not install Vivado in its default location ``/opt``, edit ``vivado.nix`` accordingly.
* Run ``$ nix-shell -I artiqSrc=path_to_artiq_sources shell-dev.nix`` to obtain an environment containing all the required development tools (e.g. Migen, MiSoC, Clang, Rust, OpenOCD...) in addition to the ARTIQ user environment. ``artiqSrc`` should point to the root of the cloned ``artiq`` repository, and ``shell-dev.nix`` can be found in the ``artiq-fast`` folder of the ``nix-scripts`` repository.
* Install the `Nix package manager <http://nixos.org/nix/>`_, version 2.4 or later. Prefer a single-user installation for simplicity.
* If you did not install Vivado in its default location ``/opt``, clone the ARTIQ Git repository and edit ``flake.nix`` accordingly.
* Enable flakes in Nix by e.g. adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (for example ``~/.config/nix/nix.conf``).
* Enter the development shell by running ``nix develop git+https://github.com/m-labs/artiq.git``, or alternatively by cloning the ARTIQ Git repository and running ``nix develop`` at the root (where ``flake.nix`` is).
* You can then build the firmware and gateware with a command such as ``$ python -m artiq.gateware.targets.kasli``. If you are using a JSON system description file, use ``$ python -m artiq.gateware.targets.kasli_generic file.json``.
* Flash the binaries into the FPGA board with a command such as ``$ artiq_flash --srcbuild -d artiq_kasli -V <your_variant>``. You need to configure OpenOCD as explained :ref:`in the user section <configuring-openocd>`. OpenOCD is already part of the shell started by ``shell-dev.nix``.
* Check that the board boots and examine the UART messages by running a serial terminal program, e.g. ``$ flterm /dev/ttyUSB1`` (``flterm`` is part of MiSoC and installed by ``shell-dev.nix``). Leave the terminal running while you are flashing the board, so that you see the startup messages when the board boots immediately after flashing. You can also restart the board (without reflashing it) with ``$ artiq_flash start``.

You can also restart the board (without reflashing it) with ``$ artiq_flash start``.
* The communication parameters are 115200 8-N-1. Ensure that your user has access to the serial device (e.g. by adding the user account to the ``dialout`` group).
.. note::
If you do not plan to modify ``nix-scripts``, with the ARTIQ channel configured you can simply enter the development Nix shell with ``nix-shell "<artiq-full/fast/shell-dev.nix>"``. No repositories need to be cloned. This is especially useful if you simply want to build firmware using an unmodified version of ARTIQ.
.. warning::
Nix will make a read-only copy of the ARTIQ source to use in the shell environment. Therefore, any modifications that you make to the source after the shell is started will not be taken into account. A solution applicable to ARTIQ (and several other Python packages such as Migen and MiSoC) is to prepend the ARTIQ source directory to the ``PYTHONPATH`` environment variable after entering the shell. If you want this to be done by default, edit ``profile`` in ``shell-dev.nix``.
