SpaceWire Verification IP
Spacecraft data links and routers: data-strobe encoding, link start-up, time codes, wormhole routing and remote memory access.
SpaceWire verification IP
SpaceWire is the standard data-handling network on spacecraft, a point-to-point serial link with packet routing.
Lumina VIP for SpaceWire covers ECSS-E-ST-50-12C · RMAP, as published by ECSS. It comes as verification IP and synthesizable transactor, built for Lumina, so the same components run in simulation and report their results in one place.
What the SpaceWire VIP covers.
Protocol
- Data-strobe encoding, characters and control codes
- Link initialisation state machine and flow-control tokens
- Time codes, packets with EOP and EEP
- Disconnect, parity and escape errors injected
Scenarios and options
- Link rates and router topologies
- RMAP remote memory access protocol
What it checks
- Word and frame formats
- Command and response timing
- Redundant buses and failover
- Error injection and monitoring
Verification IP capabilities
- Active and passive agents for every protocol role, set per instance
- Bus widths, timing and optional features set by parameters, and changeable while a test runs
- A sequence library from basic directed traffic to constrained-random stress
- Error injection, static or on the fly, with checks that the expected error was seen
- Protocol checks that run in real time, each tied to a rule of the specification
- Scoreboards that check data end to end
- Throughput, latency and utilisation statistics for each interface
- Callbacks at each stage for your own checks and stimulus
- UVM register model adapters for protocols that carry register access
- Transaction logs and messages linked to the waveform for debug
Transactor capabilities
- Synthesizable RTL for FPGA prototypes and emulators
- A transaction-level interface, so tests move unchanged from simulation
- Protocol checkers and monitors that run at hardware speed
- Streaming and buffered modes for throughput
Why Lumina VIP.
- Fast SpaceWire testbench bring-up: connect the agents, pick a test and run
- Every failure names the rule it broke and the transaction that broke it
- Protocol coverage merges with your design coverage in one database
- Readable SystemVerilog and UVM source your team can extend
- The same scenarios run in simulation, on FPGA and on silicon
- Runs natively in Lumina Sim, with no wrappers and no separate compile
- Results structured for engineers and AI agents alike
Verification components.
Each component works on its own or together with the others in one environment, in active or passive mode.

Frequently asked questions.
What is Lumina VIP for SpaceWire?
Lumina VIP for SpaceWire is a set of verification products for designs that use SpaceWire: verification IP and synthesizable transactor. Spacecraft data links and routers: data-strobe encoding, link start-up, time codes, wormhole routing and remote memory access.
Which SpaceWire versions does it support?
ECSS-E-ST-50-12C · RMAP, as published by ECSS. If you need another version or option, tell us which one.
Which verification components are included?
Node, Router-side agent and Passive monitor. Each one can be used on its own or together with the others in one environment.
What language and methodology does it use?
The verification IP and models are written in SystemVerilog with UVM, as readable source your team can extend. The transactors are synthesizable RTL for FPGA prototyping and hardware-assisted verification.
How does it work with Lumina?
It runs in Lumina Sim beside your RTL. Protocol coverage merges into the same database as your own coverage, and every violation names the rule it broke and the transaction that broke it.
Which tests come with it?
Directed tests for each feature of the specification. Constrained-random tests across configurations and traffic mixes. Error-injection tests that check how the design recovers. A functional coverage model mapped to the specification. Regression lists ready to run in Lumina. For this protocol family the tests focus on: every message and word format, redundant channels and switchover, timing and gap limits and word, parity and coding errors.
What is delivered?
Readable source of every component. The test suite and its coverage model. An example environment connected to a sample design. User guide, integration guide and release notes. Scripts to run the examples in Lumina.
