DisplayPort Automotive Extensions Verification IP
Functional safety and security additions to DisplayPort for in-vehicle displays: frame integrity checks and protected channels.
DisplayPort Automotive Extensions verification IP
DisplayPort Automotive Extensions add functional-safety and security features to DisplayPort for vehicle displays.
Lumina VIP for DisplayPort Automotive Extensions covers DP AE 1.0, as published by VESA. It comes as verification IP, built for Lumina, so the same components run in simulation and report their results in one place.
What the DisplayPort Automotive Extensions VIP covers.
Features
- Frame CRC and image integrity checks
- Region-of-interest protection and safety messaging
Checks and error injection
- Safety messages carried in secondary data packets
- Frame counters and freeze-frame detection
- Corrupted frames and lost messages injected
Scenarios and options
- Region-of-interest CRC checks per frame
What it checks
- Video timing and pixel formats
- Link training and auxiliary channels
- Audio and metadata packets
- Content protection and compression where defined
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 DisplayPort Automotive Extensions 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.

Frequently asked questions.
What is Lumina VIP for DisplayPort Automotive Extensions?
Lumina VIP for DisplayPort Automotive Extensions is a set of verification products for designs that use DisplayPort Automotive Extensions: verification IP. Functional safety and security additions to DisplayPort for in-vehicle displays: frame integrity checks and protected channels.
Which DisplayPort Automotive Extensions versions does it support?
DP AE 1.0, as published by VESA. If you need another version or option, tell us which one.
Which verification components are included?
Source, Sink 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.
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: video timings and formats across resolutions, link training and hot-plug, audio and metadata packets and link 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.
