A software framework for Linux device drivers aimed at supporting controls and data acquisition hardware. ZIO supports sub-nanosecond timestamps, block-oriented input and output and transport of meta-data with the data samples. Users can change the buffer type and trigger type associated with a device at run time, and all of devices, triggers and buffers are easily implemented as add-on modules.

The PF_ZIO implementation, currently in beta status, implements a network interface to the ZIO transport, which allows each I/O channel to generate or receive network frames. Applications see the network of devices and can talk with several of them from the same socket. We support SOCK_STREAM, SOCK_DGRAM and SOCK_RAW.

Collection of WRTD reference designs provided by (and used at) CERN

wbgen2 is a tool for generating VHDL/Verilog cores which implement Wishbone bus slaves with certain registers, memory blocks, FIFOs and interrupts. The input is a C-like syntax file with an abstract description of what do we want to have in the slave. As a result, we get:

- Automatically allocated memory layout

- VHDL/Verilog code for the slave module

- C header files for driver development - Nice HTML documentation

White Rabbit Trigger Distribution project. More info at the Wiki page

This project guides new users to start in the White Rabbit “World” with simple experiments. The starting kit uses two SPEC + FMC-DIO cards. Each node allows basic operations such as input timestamping or programmable output pulse generation. Additionally, specific software and gateware layers allow to use it as a standard network interface card implementing the White Rabbit technology functionalities.

This project covers all efforts geared to standardize White Rabbit, with a view to providing a stable specification which everyone can use to build compliant products.

A White Rabbit compliant Network Interface Card (NIC) based on the SPEC and the DIO FMC. This project hosts the HDL and associated software to configure the SPEC so it behaves as a NIC under the Linux OS.

This project hosts compliance tests dedicated for WR devices and based on the ATTEST framework available from Veryx Technologies. To use the material available in this project, the ATTEST framework needs to be purchased.

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

Configuration and boot software required to start up the SPEC7 board

On the Open Hardware Repository you can find projects which use soft-cpu (e.g. mock-turtle, white-rabbit-core, wr-switch). This project offers a toolchain that you can use to compile your code for the soft-cpu target (only LM32 for the time being). The project provides only the necessary makefiles to build the toolchain, so it will be necessary to compile the toolchain.

Software support for the SVEC board, including kernel and user-space Linux code.

A simple VME64x carrier for two low pin count FPGA Mezzanine Cards (VITA 57). It has memory and clocking resources and supports the White Rabbit timing and control network. Commercially available. More info at the Wiki page

Software support for the SPEC board, including kernel and user-space Linux code. The package also include the fmc-bus driver, which is expected to be used by other carriers as well.

A simple 4-lane PCIe carrier for a low pin count FPGA Mezzanine Card (VITA 57). It supports the White Rabbit timing and control network. Commercially available. Linux and Labview drivers available for some mezzanine cards. More info at the Wiki page

SDB (Self-describing Bus) allows to enumerate the cores that are live in the current FPGA binary, either from the host computer or from the internal soft-core CPU in the FPGA itself. The project provides the software support and the specification. More info at the Wiki page

This is a port of an older Linux ptpd to support White Rabbit extensions and run both in hosted and freestanding environment. In the future we plan to replace it with PPSI, which has a much better design, but ptp-noposix is currently working pretty well despite being difficult to maintain.
