@ -7,23 +7,48 @@ 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
* ``get()``, ``get_mu()``, ``get_att()``, and ``get_att_mu()`` functions added for AD9910 and AD9912
* Compiler:
- Supports kernel decorator with paths.
- Faster compilation for large arrays/lists.
* Phaser:
- Improved documentation
- Expose the DAC coarse mixer and sif_sync
- 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
* ``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.

* New hardware support:

ADC and FPGA.
- Zynq SoC core devices, enabling kernels to run on 1 GHz CPU core with a floating-point
- 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
@ -93,6 +118,9 @@ 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``).

"""Apply the staged interpolator configuration on the specified channels.
Each Fastino channel includes a fourth order (cubic) CIC interpolator with
variable rate change and variable output gain compensation (see
:meth:`stage_cic`).
Channels using non-unity interpolation rate should have
continous DAC updates enabled (see :meth:`set_continuous`) unless
their output is supposed to be constant.
This method resets and settles the affected interpolators. There will be
no output updates for the next `order = 3` input samples.
Affected channels will only accept one input sample per input sample
period. This method synchronizes the input sample period to the current
frame on the affected channels.
If application of new interpolator settings results in a change of the
overall gain, there will be a corresponding output step.
