Description: Designed for high-density onboard networks, our SpaceWire Router IP Core provides a robust switching matrix compliant with the ECSS-E-ST-50-12C Rev.1 standard. It enables seamless packet routing between four independent SpaceWire ports using an optimized wormhole routing architecture. This "Gateware-only" version is stripped of unnecessary protocol overhead to ensure the lowest possible LUT footprint, making it ideal for integration into resource-constrained FPGAs (ProASIC3, RTG4, Artix-7). Key Features: - Non-Blocking Matrix: Simultaneous switching across all ports with zero-jitter arbitration. - Routing Modes: Support for Path, Logical, and Regional addressing. - Low Latency: Optimized internal data paths for real-time instrument data handling. - Clock Domain Isolation: Each port operates on its own clock, simplifying system integration. - Fault Tolerance: Automatic error detection and link recovery state machines on every port. Technical Specs: - Throughput: Up to 200 Mbps per port (dependant on FPGA target). - Format: Encrypted Bitstream / Netlist for specific FPGA targets. - Option: RMAP Target Configuration module available upon request (increases LUT count) Beyond simple packet switching, the RMAP version integrates a full Target engine dedicated to router management. It allows your flight computer to perform remote diagnostics, monitor link status, and reconfigure routing tables on-the-fly via standard RMAP commands. Remote Management: Access internal status registers (error counts, link state) without extra hardware pins. Dynamic Routing: Update logical addresses and path permissions remotely during the mission. Mission Critical: Designed for satellites requiring high availability and in-flight reconfigurability. 8 Hours of Expert Technical Support (Network topology design, routing table configuration, and hardware validation).
