Diagnostic SpaceWire Interface (DSI)

The 4Links Diagnostic SpaceWire Interface (DSI) is a high-performance Ethernet to SpaceWire bridge, connecting up to eight simultaneously active SpaceWire ports.

The Diagnostic SpaceWire Interface (DSI) enables you to test up to eight ports concurrently, with diagnostics that have detected and resolved many problems that were previously either undetected or long unsolved. The link speed can be set at up to 400 Mb/s in steps of 1 Mbit/s or less.

Diagnostics include time-tagging and waveform capture (with better than 2 nanosecond resolution), extensive and repeatable error injection, and packet transmissions synchronized to start or end at the same time, typically to within less than 10 nanosecond of each other, or with fixed offsets. All SpaceWire interrupt codes and time codes (including multiple codes) can be transferred in both directions between SpaceWire and the user. All data transfers, in both directions on all ports, can be recorded for subsequent analysis or playback.

DSI units can be synchronized with other DSI units so that time-tags and synchronized outputs are consistent over a system with many SpaceWire links. DSI units can also be synchronized with other units such as the Multi-link SpaceWire Recorder (MSR) and the SpaceWire RMAP Responder (SRR). Additionally, all of these units may be synchronised to clock-time using the Absolute Time Interface (ATI).
