Corelib - Project to share generic HDL cores.

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

A VHDL core for a VME64x slave. The other side behaves like a Wishbone master.

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 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

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

PHASE (Portable Hardware Analyzer with Sharing Explorer) aims at unifying hardware debugging in a single tool. From the host machine, a user may graphically interconnect components to describe the connection between his computer and the target device to debug. For example, a USB JTAG cable might be the root node, connected to an Arria2 development board with a CPLD and an FPGA, containing a LM32 processor.

Wherever possible, PHASE fetches design descriptions from the internet based on the detected JTAG IDCODEs, USB vendor IDs, or PnP BUS information. In the preceding example, each step of the chain would be automatically detected. The USB cable from the vendor+product codes, the FPGA from the JTAG IDCODE and the LM32 from the Arria2's sld hub. The user would now be presented with read/write access to the data and instruction buses for visual inspection or firmware loading. Furthermore, the user could launch gdb to halt and single-step the embedded LM32 CPU.

If a device is not yet described, the user may assemble a driver out of the reusable software components. For example, an Altera USB-Blaster driver is just a FTDI device chained with a byte packeter and a JTAG bit banger. Once the design has been graphically assembled, it is automatically scanned for attached JTAG devices and the USB cable design is shared online with any future users of the same cable.

This project defines data structures, to be embedded in the FPGA memory address space, to enumerate the devices that have been synthetized in the current design. The same structure is also used as a simple flash file system. AKA Self-Describing Bus (SDB) Specification for Logic Cores. The layout is simple enough to be parsed both by the host and by the internal soft-core, if any.

The documentation is public, and related code is GNU GPL licensed.

FmcDIO5chTTLa is a 5-bit port digital IO card in FMC form-factor. Each single-bit port can be configured individually as input or output. The I/Os on LEMO 00 connectors are TTL compatible. Commercially available. More info at the Wiki page

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 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.

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.

A cute-wr is a compact WR-node implementation with minimum components required. The initial design is derived from SPEC, but would work in an opposite manner as a FMC wr-nic, providing 2 DIO channels, external CLK input, EEPROM, JTAG, RS232, and expandable IOs through FMC connector. The gateware and software of cute-wr would also keep maximum compatibility with SPEC. Project is obsolete. See cute-wr-dp for a similar board.

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.

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.

Host-side software support for the fine delay FMC on the SPEC and SVEC FMC carriers.

Software to support the fmc-adc-100m14b4cha mezzanine, including Linux device driver, library and test program.

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.
