This project covers the hardware development of version 4 of the White Rabbit switch (WRS-v4). More info at the Wiki page

A collection of cores needed in the White Rabbit node and switch. Includes White Rabbit PTP Core (WRPC).

Development of software for the White Rabbit switch, and in particular the embedded Linux system running in the ARM9 processor. More info at the Wiki page

A Precise Time Protocol (PTP, IEEE 1588) software stack whose single source code can be compiled for many architectures (POSIX systems, WR switch, WR node, ...) and which is easily extensible.

The Macbeth (MAChine / BEamline Timing Hardware) system is aimed to synchronize the beamlines experimental devices (pump-probe, laser, …) with the accelerator beam with a high accuracy

Distributed I/O Tier - these are electronics modules installed close to a particle accelerator in radiation-exposed or radiation-free areas controlled by the master in the Front-end tier over the fieldbus. These are usually FPGA-based boards sampling digital and analog inputs, driving outputs and performing various safety critical operations. More info at the Wiki page

White Rabbit PTP Core software for LatticeMico32. It consists of a software wrapper for running a PTP daemon without an operating system and device drivers for WRPC HDL internals.

This project contains all the HDL gateware necessary for the FPGA of the WR switch.

Production and functional tests for FMC TDC 1ns 5cha.

A USB controlled switch box with 1 to 4 switching. Can send out a reference voltage. Multiple configurations possible. Used for the calibration of ADC, TDC and Fine delay mezzanines. More info at the Wiki page

Radiation-tolerant AC/DC power supply unit (PSU). In: 230VAC, 50Hz, Out: +12V, 8.33A (100W) and +5V, 2A (10W). Possibility for redundancy. The design is CompactPCI compatible. Part of DIOT project.

DI/OT Zynq Ultrascale-based System Board with White Rabbit support. More info at the Wiki page

Tool for generating multi-purpose makefiles for FPGA projects.

Main features:

makefile generation for: fetching modules from repositories simulating HDL projects synthesizing HDL projects synthesizing projects remotely (keeping your local resources free) generating multi-vendor project files (no clicking in the IDE!) many other things without involving make and makefiles

Hdlmake supports modularity, scalability, revision control systems. Hdlmake can be run on any Linux or Windows machine with any HDL More info at the Wiki page

A collection of platform-independent cores such as memories, synchronizer circuits and Wishbone cores.

More info at the Wiki page

DIOT 3U crate mechanics and backplane compliant with CompactPCI-Serial standard.

A meta project used to discuss and present information about Open Hardware and related subjects. More info at the Wiki page More info about the CERN Open Hardware licence More info about the OHR.org site support

A fully open electronic watch project featuring an integrated GPS receiver. More info at the Wiki page

BabyWR is a general purpose small pluggable WR node in a M.2 form-factor. More info at the Wiki page

White Rabbit is a fully deterministic Ethernet-based network for general purpose data transfer and synchronization. It can synchronize over 1000 nodes with sub-ns accuracy over fiber lengths of up to 10 km. Commercially available. More info at the Wiki page

A fine delay generator in FMC LPC format with 1 input and 2 outputs. The resolution is 1 ns. Optimized for high frequency pulse repetition rates synchronized to an external clock. More info at the Wiki page
