Release notes
|
||
=============
|
||
|
||
ARTIQ-7
|
||
-------
|
||
|
||
Highlights:
|
||
|
||
* Support for Kasli-SoC, a new EEM carrier based on a Zynq SoC, enabling much faster kernel execution.
|
||
* 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.
|
||
* 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
|
||
* On Kasli, the number of FIFO lanes in the scalable events dispatcher (SED) can now be configured in
|
||
the JSON hardware description file.
|
||
* New hardware support:
|
||
- HVAMP_8CH 8 channel HV amplifier for Fastino / Zotino
|
||
* ``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"})``.
|
||
|
||
Breaking changes:
|
||
|
||
* 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
|
||
generated for some configurations.
|
||
* 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.
|
||
|
||
|
||
ARTIQ-6
|
||
-------
|
||
|
||
Highlights:
|
||
|
||
* New hardware support:
|
||
- Phaser, a quad channel 1GS/s RF generator card with dual IQ upconverter and dual 5MS/s
|
||
ADC and FPGA.
|
||
- Zynq SoC core device (ZC706), enabling kernels to run on 1 GHz CPU core with a floating-point
|
||
unit for faster computations. This currently requires an external
|
||
repository (https://git.m-labs.hk/m-labs/artiq-zynq).
|
||
- Mirny 4-channel wide-band PLL/VCO-based microwave frequency synthesiser
|
||
- Fastino 32-channel, 3MS/s per channel, 16-bit DAC EEM
|
||
- Kasli 2.0, an improved core device with 12 built-in EEM slots, faster FPGA, 4 SFPs, and
|
||
high-precision clock recovery circuitry for DRTIO (to be supported in ARTIQ-7).
|
||
* ARTIQ Python (core device kernels):
|
||
- Multidimensional arrays are now available on the core device, using NumPy syntax.
|
||
Elementwise operations (e.g. ``+``, ``/``), matrix multiplication (``@``) and
|
||
multidimensional indexing are supported; slices and views are not yet.
|
||
- Trigonometric and other common math functions from NumPy are now available on the
|
||
core device (e.g. ``numpy.sin``), both for scalar arguments and implicitly
|
||
broadcast across multidimensional arrays.
|
||
- Failed assertions now raise ``AssertionError``\ s instead of aborting kernel
|
||
execution.
|
||
* Performance improvements:
|
||
- SERDES TTL inputs can now detect edges on pulses that are shorter
|
||
than the RTIO period (https://github.com/m-labs/artiq/issues/1432)
|
||
- 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).
|
||
- 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:
|
||
- Applets now restart if they are running and a ccb call changes their spec
|
||
- A "Quick Open" dialog to open experiments by typing part of their name can
|
||
be brought up Ctrl-P (Ctrl+Return to immediately submit the selected entry
|
||
with the default arguments).
|
||
- The Applets dock now has a context menu command to quickly close all open
|
||
applets (shortcut: Ctrl-Alt-W).
|
||
* Experiment results are now always saved to HDF5, even if ``run()`` fails.
|
||
* Core device: ``panic_reset 1`` now correctly resets the kernel CPU as well if
|
||
communication CPU panic occurs.
|
||
* NumberValue accepts a ``type`` parameter specifying the output as ``int`` or ``float``
|
||
* A parameter ``--identifier-str`` has been added to many targets to aid
|
||
with reproducible builds.
|
||
* Python 3.7 support in Conda packages.
|
||
* `kasli_generic` JSON descriptions are now validated against a
|
||
schema. Description defaults have moved from Python to the
|
||
schema. Warns if ARTIQ version is too old.
|
||
|
||
Breaking changes:
|
||
|
||
* ``artiq_netboot`` has been moved to its own repository at
|
||
https://git.m-labs.hk/m-labs/artiq-netboot
|
||
* Core device watchdogs have been removed.
|
||
* The ARTIQ compiler now implements arrays following NumPy semantics, rather than as a
|
||
thin veneer around lists. Most prior use cases of NumPy arrays in kernels should work
|
||
unchanged with the new implementation, but the behavior might differ slightly in some
|
||
cases (for instance, non-rectangular arrays are not currently supported).
|
||
* ``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``).
|
||
|
||
|
||
ARTIQ-5
|
||
-------
|
||
|
||
Highlights:
|
||
|
||
* Performance improvements:
|
||
- Faster RTIO event submission (1.5x improvement in pulse rate test)
|
||
See: https://github.com/m-labs/artiq/issues/636
|
||
- Faster compilation times (3 seconds saved on kernel compilation time on a typical
|
||
medium-size experiment)
|
||
See: https://github.com/m-labs/artiq/commit/611bcc4db4ed604a32d9678623617cd50e968cbf
|
||
* Improved packaging and build system:
|
||
- new continuous integration/delivery infrastructure based on Nix and Hydra,
|
||
providing reproducibility, speed and independence.
|
||
- rolling release process (https://github.com/m-labs/artiq/issues/1326).
|
||
- firmware, gateware and device database templates are automatically built for all
|
||
supported Kasli variants.
|
||
- new JSON description format for generic Kasli systems.
|
||
- Nix packages are now supported.
|
||
- many Conda problems worked around.
|
||
- controllers are now out-of-tree.
|
||
- split packages that enable lightweight applications that communicate with ARTIQ,
|
||
e.g. controllers running on non-x86 single-board computers.
|
||
* Improved Urukul support:
|
||
- AD9910 RAM mode.
|
||
- Configurable refclk divider and PLL bypass.
|
||
- More reliable phase synchronization at high sample rates.
|
||
- Synchronization calibration data can be read from EEPROM.
|
||
* A gateware-level input edge counter has been added, which offers higher
|
||
throughput and increased flexibility over the usual TTL input PHYs where
|
||
edge timestamps are not required. See ``artiq.coredevice.edge_counter`` for
|
||
the core device driver and ``artiq.gateware.rtio.phy.edge_counter``/
|
||
``artiq.gateware.eem.DIO.add_std`` for the gateware components.
|
||
* With DRTIO, Siphaser uses a better calibration mechanism.
|
||
See: https://github.com/m-labs/artiq/commit/cc58318500ecfa537abf24127f2c22e8fe66e0f8
|
||
* Schedule updates can be sent to influxdb (artiq_influxdb_schedule).
|
||
* Experiments can now programatically set their default pipeline, priority, and flush flag.
|
||
* List datasets can now be efficiently appended to from experiments using
|
||
``artiq.language.environment.HasEnvironment.append_to_dataset``.
|
||
* The core device now supports IPv6.
|
||
* To make development easier, the bootloader can receive firmware and secondary FPGA
|
||
gateware from the network.
|
||
* Python 3.7 compatibility (Nix and source builds only, no Conda).
|
||
* Various other bugs from 4.0 fixed.
|
||
* Preliminary Sayma v2 and Metlino hardware support.
|
||
|
||
Breaking changes:
|
||
|
||
* The ``artiq.coredevice.ad9910.AD9910`` and
|
||
``artiq.coredevice.ad9914.AD9914`` phase reference timestamp parameters
|
||
have been renamed to ``ref_time_mu`` for consistency, as they are in machine
|
||
units.
|
||
* The controller manager now ignores device database entries without the
|
||
``command`` key set to facilitate sharing of devices between multiple
|
||
masters.
|
||
* The meaning of the ``-d/--dir`` and ``--srcbuild`` options of ``artiq_flash``
|
||
has changed.
|
||
* Controllers for third-party devices are now out-of-tree.
|
||
* ``aqctl_corelog`` now filters log messages below the ``WARNING`` level by default.
|
||
This behavior can be changed using the ``-v`` and ``-q`` options like the other
|
||
programs.
|
||
* On Kasli the firmware now starts with a unique default MAC address
|
||
from EEPROM if `mac` is absent from the flash config.
|
||
* The ``-e/--experiment`` switch of ``artiq_run`` and ``artiq_compile``
|
||
has been renamed ``-c/--class-name``.
|
||
* ``artiq_devtool`` has been removed.
|
||
* Much of ``artiq.protocols`` has been moved to a separate package ``sipyco``.
|
||
``artiq_rpctool`` has been renamed to ``sipyco_rpctool``.
|
||
|
||
|
||
ARTIQ-4
|
||
-------
|
||
|
||
4.0
|
||
***
|
||
|
||
* The ``artiq.coredevice.ttl`` drivers no longer track the timestamps of
|
||
submitted events in software, requiring the user to explicitly specify the
|
||
timeout for ``count()``/``timestamp_mu()``. Support for ``sync()`` has been dropped.
|
||
|
||
Now that RTIO has gained DMA support, there is no longer a reliable way for
|
||
the kernel CPU to track the individual events submitted on any one channel.
|
||
Requiring the timeouts to be specified explicitly ensures consistent API
|
||
behavior. To make this more convenient, the ``TTLInOut.gate_*()`` functions
|
||
now return the cursor position at the end of the gate, e.g.::
|
||
|
||
ttl_input.count(ttl_input.gate_rising(100 * us))
|
||
|
||
In most situations – that is, unless the timeline cursor is rewound after the
|
||
respective ``gate_*()`` call – simply passing ``now_mu()`` is also a valid
|
||
upgrade path::
|
||
|
||
ttl_input.count(now_mu())
|
||
|
||
The latter might use up more timeline slack than necessary, though.
|
||
|
||
In place of ``TTL(In)Out.sync``, the new ``Core.wait_until_mu()`` method can
|
||
be used, which blocks execution until the hardware RTIO cursor reaches the
|
||
given timestamp::
|
||
|
||
ttl_output.pulse(10 * us)
|
||
self.core.wait_until_mu(now_mu())
|
||
* RTIO outputs use a new architecture called Scalable Event Dispatcher (SED),
|
||
which allows building systems with large number of RTIO channels more
|
||
efficiently.
|
||
From the user perspective, collision errors become asynchronous, and non-
|
||
monotonic timestamps on any combination of channels are generally allowed
|
||
(instead of producing sequence errors).
|
||
RTIO inputs are not affected.
|
||
* The DDS channel number for the NIST CLOCK target has changed.
|
||
* The dashboard configuration files are now stored one-per-master, keyed by the
|
||
server address argument and the notify port.
|
||
* The master now has a ``--name`` argument. If given, the dashboard is labelled
|
||
with this name rather than the server address.
|
||
* ``artiq_flash`` targets Kasli by default. Use ``-t kc705`` to flash a KC705
|
||
instead.
|
||
* ``artiq_flash -m/--adapter`` has been changed to ``artiq_flash -V/--variant``.
|
||
* The ``proxy`` action of ``artiq_flash`` is determined automatically and should
|
||
not be specified manually anymore.
|
||
* ``kc705_dds`` has been renamed ``kc705``.
|
||
* The ``-H/--hw-adapter`` option of ``kc705`` has been renamed ``-V/--variant``.
|
||
* SPI masters have been switched from misoc-spi to misoc-spi2. This affects
|
||
all out-of-tree RTIO core device drivers using those buses. See the various
|
||
commits on e.g. the ``ad53xx`` driver for an example how to port from the old
|
||
to the new bus.
|
||
* The ``ad5360`` coredevice driver has been renamed to ``ad53xx`` and the API
|
||
has changed to better support Zotino.
|
||
* ``artiq.coredevice.dds`` has been renamed to ``artiq.coredevice.ad9914`` and
|
||
simplified. DDS batch mode is no longer supported. The ``core_dds`` device
|
||
is no longer necessary.
|
||
* The configuration entry ``startup_clock`` is renamed ``rtio_clock``. Switching
|
||
clocks dynamically (i.e. without device restart) is no longer supported.
|
||
* ``set_dataset(..., save=True)`` has been renamed
|
||
``set_dataset(..., archive=True)``.
|
||
* On the AD9914 DDS, when switching to ``PHASE_MODE_CONTINUOUS`` from another mode,
|
||
use the returned value of the last ``set_mu`` call as the phase offset for
|
||
``PHASE_MODE_CONTINUOUS`` to avoid a phase discontinuity. This is no longer done
|
||
automatically. If one phase glitch when entering ``PHASE_MODE_CONTINUOUS`` is not
|
||
an issue, this recommendation can be ignored.

||

* To accommodate larger runtimes, the flash layout as changed. As a result, the
|

contents of the flash storage will be lost when upgrading. Set the values back
|
||
(IP, MAC address, startup kernel, etc.) after the upgrade.

|
||
|
||
No further notes.
|
||
|
||
|
||
3.0
|
||
***
|
||
|
||
* The ``--embed`` option of applets is replaced with the environment variable
|
||
``ARTIQ_APPLET_EMBED``. The GUI sets this enviroment variable itself and the
|
||
user simply needs to remove the ``--embed`` argument.
|
||
* ``EnvExperiment``'s ``prepare`` calls ``prepare`` for all its children.
|
||
* Dynamic ``__getattr__``'s returning RPC target methods are not supported anymore.
|
||
Controller driver classes must define all their methods intended for RPC as
|
||
members.
|
||
* Datasets requested by experiments are by default archived into their HDF5
|
||
output. If this behavior is undesirable, turn it off by passing
|
||
``archive=False`` to ``get_dataset``.
|
||
* ``seconds_to_mu`` and ``mu_to_seconds`` have become methods of the core
|
||
device driver (use e.g. ``self.core.seconds_to_mu()``).
|
||
* AD9858 DDSes and NIST QC1 hardware are no longer supported.
|
||
* The DDS class names and setup options have changed, this requires an update of
|
||
the device database.
|
||
* ``int(a, width=b)`` has been removed. Use ``int32(a)`` and ``int64(a)``.
|
||
* The KC705 gateware target has been renamed ``kc705_dds``.
|
||
* ``artiq.coredevice.comm_tcp`` has been renamed ``artiq.coredevice.comm_kernel``,
|
||
and ``Comm`` has been renamed ``CommKernel``.
|
||
* The "collision" and "busy" RTIO errors are reported through the log instead of
|
||
raising exceptions.
|
||
* Results are still saved when ``analyze`` raises an exception.
|
||
* ``LinearScan`` and ``RandomScan`` have been consolidated into RangeScan.
|
||
* The Pipistrello is no longer supported. For a low-cost ARTIQ setup, use either
|
||
ARTIQ 2.x with Pipistrello, or the future ARTIQ 4.x with Kasli. Note that the
|
||
Pipistrello board has also been discontinued by the manufacturer but its design
|
||
files are freely available.
|
||
* The device database is now generated by an executable Python script. To migrate
|
||
an existing database, add ``device_db = `` at the beginning, and replace any PYON
|
||
identifiers (``true``, ``null``, ...) with their Python equivalents
|
||
(``True``, ``None`` ...).
|
||
* Controllers are now named ``aqctl_XXX`` instead of ``XXX_controller``.
|
||
* In the device database, the ``comm`` device has been folded into the ``core`` device.
|
||
Move the "host" argument into the ``core`` device, and remove the ``comm`` device.
|
||
* The core device log now contains important information about events such as
|
||
RTIO collisions. A new controller ``aqctl_corelog`` must be running to forward
|
||
those logs to the master. See the example device databases to see how to
|
||
instantiate this controller. Using ``artiq_session`` ensures that a controller
|
||
manager is running simultaneously with the master.
|
||
* Experiments scheduled with the "flush pipeline" option now proceed when there
|
||
are lower-priority experiments in the pipeline. Only experiments at the current
|
||
(or higher) priority level are flushed.
|
||
* The PDQ(2/3) driver has been removed and is now being maintained out-of tree
|
||
at https://github.com/m-labs/pdq. All SPI/USB driver layers, Mediator,
|
||
CompoundPDQ and examples/documentation has been moved.
|
||
* The master now rotates log files at midnight, rather than based on log size.
|
||
* The results keys ``start_time`` and ``run_time`` are now stored as doubles of UNIX time,
|
||
rather than ints. The file names are still based on local time.
|
||
* Packages are no longer available for 32-bit Windows.

|
||
* The format of the influxdb pattern file is simplified. The procedure to
|
||
edit patterns is also changed to modifying the pattern file and calling:
|
||
``artiq_rpctool.py ::1 3248 call scan_patterns`` (or restarting the bridge)
|
||
The patterns can be converted to the new format using this code snippet::
|
||
|
||
from artiq.protocols import pyon
|
||
patterns = pyon.load_file("influxdb_patterns.pyon")
|
||
for p in patterns:
|
||
print(p)
|
||
|
||
* The "GUI" has been renamed the "dashboard".
|
||
* When flashing NIST boards, use "-m nist_qcX" or "-m nist_clock" instead of
|
||
just "-m qcX" or "-m clock" (#290).
|
||
* Applet command lines now use templates (e.g. $python) instead of formats
|
||
(e.g. {python}).
|
||
* On Windows, GUI applications no longer open a console. For debugging
|
||
purposes, the console messages can still be displayed by running the GUI
|
||
applications this way::
|
||
|
||
python3.5 -m artiq.frontend.artiq_browser
|
||
python3.5 -m artiq.frontend.artiq_dashboard
|
||
|
||
(you may need to replace python3.5 with python)
|
||
Please always include the console output when reporting a GUI crash.
|
||
* The result folders are formatted "%Y-%m-%d/%H instead of "%Y-%m-%d/%H-%M".
|
||
(i.e. grouping by day and then by hour, instead of by day and then by minute)
|
||
* The ``parent`` keyword argument of ``HasEnvironment`` (and ``EnvExperiment``)
|
||
has been replaced. Pass the parent as first argument instead.
|
||
* During experiment examination (and a fortiori repository scan), the values of
|
||
all arguments are set to ``None`` regardless of any default values supplied.
|
||
* In the dashboard's experiment windows, partial or full argument recomputation
|
||
takes into account the repository revision field.
|
||
* By default, ``NumberValue`` and ``Scannable`` infer the scale from the unit
|
||
for common units.
|
||
* By default, artiq_client keeps the current persist flag on the master.
|
||
* GUI state files for the browser and the dashboard are stores in "standard"
|
||
locations for each operating system. Those are
|
||
``~/.config/artiq/2/artiq_*.pyon`` on Linux and
|
||
``C:\Users\<username>\AppData\Local\m-labs\artiq\2\artiq_*.pyon`` on
|
||
Windows 7.
|
||
* The position of the time cursor is kept across experiments and RTIO resets
|
||
are manual and explicit (inter-experiment seamless handover).
|
||
* All integers manipulated by kernels are numpy integers (numpy.int32,
|
||
numpy.int64). If you pass an integer as a RPC argument, the target function
|
||
receives a numpy type.

1.0rc4
|

******
|
||
|
||
* setattr_argument and setattr_device add their key to kernel_invariants.
|

|
||
|
||
1.0rc3
|
||
******
|
||
|
||
* The HDF5 format has changed.
|
||
|
||
* The datasets are located in the HDF5 subgroup ``datasets``.
|
||
* Datasets are now stored without additional type conversions and annotations
|
||
from ARTIQ, trusting that h5py maps and converts types between HDF5 and
|
||
python/numpy "as expected".
|
||
|
||
* NumberValue now returns an integer if ``ndecimals`` = 0, ``scale`` = 1 and
|
||
``step`` is integer.
|
||
|
||
|
||
1.0rc2
|
||
******
|
||
|
||
* The CPU speed in the pipistrello gateware has been reduced from 83 1/3 MHz to
|
||
75 MHz. This will reduce the achievable sustained pulse rate and latency
|
||
accordingly. ISE was intermittently failing to meet timing (#341).
|
||
* set_dataset in broadcast mode no longer returns a Notifier. Mutating datasets
|
||
should be done with mutate_dataset instead (#345).
|
||
|
||
|
||
1.0rc1
|
||
******
|
||
|
||
* Experiments (your code) should use ``from artiq.experiment import *``
|
||
(and not ``from artiq import *`` as previously)
|
||
* Core device flash storage has moved due to increased runtime size.
|
||
This requires reflashing the runtime and the flash storage filesystem image
|
||
or erase and rewrite its entries.
|
||
* ``RTIOCollisionError`` has been renamed to ``RTIOCollision``
|
||
* the new API for DDS batches is::
|
||
|
||
with self.core_dds.batch:
|
||
...
|
||
|
||
with ``core_dds`` a device of type ``artiq.coredevice.dds.CoreDDS``.
|
||
The dds_bus device should not be used anymore.
|
||
* LinearScan now supports scanning from high to low. Accordingly,
|
||
its arguments ``min/max`` have been renamed to ``start/stop`` respectively.
|
||
Same for RandomScan (even though there direction matters little).
