ARTIQ uses FPGA hardware to perform its time-critical tasks.
|
||||
It is designed to be portable to hardware platforms from different vendors and FPGA manufacturers.
|
||||
Currently, one configuration of a `low-cost open hardware FPGA board <http://pipistrello.saanlima.com/>`_ and several different configurations of a `high-end FPGA evaluation kit <http://www.xilinx.com/products/boards-and-kits/ek-k7-kc705-g.html>`_ are used and supported.
|
||||
Any of these FPGA platforms can be combined with any number of additional peripherals, either already accessible from ARTIQ or made accessible with little effort.

Custom hardware components with widely extended capabilities and advanced support for scalable and fully distributed real-time control of experiments `are being designed <https://github.com/m-labs/artiq-hardware>`_.

* ``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 Pipistrello port now has exclusively TTLs.
|

* 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)``.

* Results are still saved when ``analyze`` raises an exception.

* LinearScan and RandomScan have been consolidated into RangeScan.

|

The low-cost Pipistrello FPGA board can be used as a lower-cost but slower alternative. Since the device does not have a native network interface, a PPP session is run over the serial port (which is then run over USB). To establish the PPP session with the core device, giving it the IP address 10.0.0.2, as root execute::
|
||||
|
||||
pppd /dev/ttyUSB1 115200 noauth nodetach local nocrtscts novj 10.0.0.1:10.0.0.2
|
||||
|
||||
.. warning:: Windows is not supported.
|
||||
|
||||
.. warning:: The Pipistrello draws a high current over USB, and that current increases when the FPGA design is active. If you experience problems such as intermittent board freezes or USB errors, try connecting it to a self-powered USB hub.
