SpaceFibre IP Cores

STAR-Dundee has developed a range of SpaceFibre IP cores which have already been designed into radiation-hardened FPGAs and ASICs. These IP cores provide the building blocks required for creating the next generation of onboard networks. The available IP cores are:

  • SpaceFibre Single-Lane Interface – Speeds ranging from 1 to 6.25 Gbit/s
  • SpaceFibre Multi-Lane Interface – Supports any number of lanes (up to 8 lanes, aggregate rates of up to 50 Gbit/s)
  • SpaceFibre Router – Number and types of ports is fully configurable (includes the possibility of configuring some ports as SpaceWire ports)
  • SpaceWire to SpaceFibre Bridge – Allows multiplexing a configurable number of SpaceWire links into a single SpaceFibre link

The IP Cores are delivered with reference designs targeting different FPGA technologies. These designs provide a path for fast adoption in the selected FPGA technology, making it easy to become familiar with the use of the IP in a specific FPGA. This in turn helps to reduce the time and effort required to implement SpaceFibre in the final design.

STAR-Dundee SpaceFibre IP cores are supported in the following radiation-hardened/tolerant FPGA families:

  • Microchip RTG4
  • Xilinx Virtex-5QV
  • Xilinx Kintex UltraScale
  • Microchip PolarFire (available soon)
  • NanoXplore BRAVE (available soon)
  • Microchip RTAX (Single-Lane Interface only)

Furthermore, support is also included for relevant commercial FPGAs including (but not limited to):

  • Microchip SmartFusion2
  • Xilinx Virtex-5
  • Xilinx Spartan-6
  • Xilinx Artix-7, Kintex-7 & Virtex-7
  • Xilinx Zynq UltraScale+
  • Altera Cyclone V (available soon)

The SpaceFibre IPs include support for external transceiver devices such as the TLK2711-SP.

If you require support for a technology not listed here or have any questions regarding the use of SpaceFibre IP cores with these technologies, please contact STAR-Dundee.

These cores are fully compliant to the ECSS-E-ST-50-11C SpaceFibre standard.

Product Features

  • Minimum implementation complexity:

    • Simple data interfaces based on standard input and output FIFO interfaces (AXI4-Stream) with independent user-defined data read and write AXI clocks
    • Easy to use with a protocol agnostic interface. No prior knowledge of SpaceFibre standard is required. The SpaceWire packet size, format and content is arbitrary
    • Highly configurable, giving flexibility through generics in the VHDL source code
    • Easily targeted for major FPGAs including radiation-hardened devices such as the Microchip RTG4 and Xilinx Virtex-5QV or Kintex UltraScale
    • Status and error reporting
    • Data and broadcast babbling-node protection
  • Maximum Performance:

    • Guaranteed timing closure in radiation-tolerant FPGAs with EDAC and SET filter enabled and worst-case conditions
    • Supports lane rates up to 3.125 Gbit/s in RTG4 or Virtex-5QV, and 6.25 Gbit/s in Kintex UltraScale
    • When Multi-Lane is used:
      • Automatic graceful degradation
      • Lanes can be configured as unidirectional to save power and mass in asymmetric data flows
      • Hot and cold redundancy supported
    • Possibility to start one end of the link in a low-power mode waiting for the other end to become active
    • Optimised for low latency operation
  • Compliant with the ECSS-E-ST-50-11C SpaceFibre standard

  • Designed by the same team who created the standard

  • Extensively tested
