CAN XL Verification IP
The third CAN generation: data fields up to 2048 bytes, higher data rates, SDU types and the PWM transceiver mode.
CAN XL verification IP
CAN XL extends CAN to payloads of up to 2048 bytes and data rates around 10 Mb/s, bridging CAN and Ethernet in zonal architectures.
Lumina VIP for CAN XL covers CiA 610 · ISO 11898-1:2024, as published by CAN in Automation. It comes as verification IP, built for Lumina, so the same components run in simulation and report their results in one place.
What the CAN XL VIP covers.
Protocol
- XL frames with SDU type, virtual CAN network ID and acceptance field
- Arbitration and data phase bit rates with PWM coding
- Mixed networks with CAN FD and classical CAN nodes
Checks and error injection
- Bit, stuff, CRC, form and acknowledge errors injected
- Error counters, error-passive and bus-off recovery
- Transceiver mode switching
- Glitches and bit-timing deviations at the tolerance limits
What it checks
- Bit timing and frame formats
- Arbitration and bus errors
- Sleep, wake-up and network management
- Fault injection for safety analysis
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
Why Lumina VIP.
- Fast CAN XL 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
- 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.
- 01Node (transmit and receive)
- 02Passive monitor and bus checker

Frequently asked questions.
What is Lumina VIP for CAN XL?
Lumina VIP for CAN XL is a set of verification products for designs that use CAN XL: verification IP. The third CAN generation: data fields up to 2048 bytes, higher data rates, SDU types and the PWM transceiver mode.
Which CAN XL versions does it support?
CiA 610 · ISO 11898-1:2024, as published by CAN in Automation. If you need another version or option, tell us which one.
Which verification components are included?
Node (transmit and receive) and Passive monitor and bus checker. 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.
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: bus traffic with many nodes and arbitration, timing at the edges of tolerance, every error type and fault confinement and sleep and wake-up.
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.
