SPI Boards Package is a set of electronic boards developed at Soleil Synchrotron (France). These boards can be connected together in a daisy chain and they communicate with an embedded controller via an SPI Bus. They provide the following features:

- Platform allowing us to build specific solutions with simple and open tools.

- Modular architecture.

- Provide solutions for applications which require synchronization.

- Low level process implementation to achieve better performance. - Easy Control network connection

The main CPU board contains a microprocessor. It manages a task for communication with the supervision, an embedded process and SPI communication with the peripheral boards. We have a modular approach that means we can make various Peripheral board combinations between 16-bit DAC, 16-bit ADC, and a calculator board for motor encoder.

A Trigger/Timing Logic Unit designed for use with High Energy Physics beam-tests. Provides a simple and flexible interface for fast timing and triggering signals at the AIDA pixel sensor beam-telescope. Connects to a FPGA carrier card via a FMC connector.

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.

IPBus is a FPGA Core that controls a Wishbone bus via Ethernet. Currently the transport protocol is UDP/IP, although there are plans for an ATA over Ethernet (AoE) implementation. There are reference designs for the SP601 and SP605 Xilinx FPGA boards.

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

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

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.
