- MiSoC and ARTIQ work well. A failure to meet timing closure on some paths in and around the mor1kx CPU is being investigated.
- 1000BASE-X Ethernet works with various SFP modules (DAC/twinax, GBIC/RJ45, 1000BASE-BX10, 10GBASE-PR) and different switches.
- The I2C tree works well and can be accessed through the USB port as well as through the FPGA. It allows configuration, identification, and debugging of EEMs, SFP modules, and the on-board CDR/PLL.
- Kasli works well when powered using power-over-ethernet (PoE). Standard 12V splitters can supply Kasli and a few of the lower power EEMs with up to 13 W (PoE, 802.3af) or 25W (PoE+, 802.3at). Higher power PoE standards should work as well. PoE also enables remote power monitoring and power cycling and reduces cabling and possible ground loops.
- The on-board Si5324 CDR/PLL and the ADCLK948 fan-out have been tested and characterized. They are used in stand-alone mode with external clock reference, as well as for DRTIO. The fan-out can also be used to supply Urukul boards with a high-quality reference without the need for external cabling. A 450 kHz phase modulation spur from the SMPS will be suppressed in future revision.
Revision v1.1 of Kasli is complete and we expect around 15 more Kasli boards to be in use soon.
The kHz phase modulation spur was traced back to the on-board oscillator leaking through the clock mux. Disabling the oscillator when using the external clock input eliminates the spurs.
The ARTIQ drivers cover most of the Urukul functionality and are currently being documented and unittests are being written.
Revision v1.1 of both Urukul variants is complete and the boards are being manufactured. We expect more than 30 Urukul boards to be in use in various laboratories soon.
The low-jitter reference frequency distribution board Clocker has been tested with excellent results.
Revision v1.1 of the 32-channel DAC has been completed with revised thermal design.
The 8-channel ADC successor of Novogorny has been been completed with revised analog input stage, changed ADC chip choice, and improved digital interface.
The 8-channel digital I/O boards have been revised and v1.2 is in production.
A distributed Thermistor/TEC controller with Ethernet and PoE connectivity is being designed.
Various 3U crates in different styles and from different vendors for housing EEMs, Kasli, and the VHDCI Carrier as well as different power supplies and cooling options have been tested. There is a wide range of compatible cases and powering options for different user preference and applications.
As part of opticlock we have completed the ARTIQ network drivers for the PTB Synthesizer.
An ARTIQ network driver for the Princeton Instruments EMCCD cameras is in the works.
