YAML generation
// the problem

Diagnostics are hard. Validating them is harder.

Building a UDS diagnostics stack from scratch on Zephyr or FreeRTOS takes four to eight engineer-weeks. Session state machines, ISO-TP framing, security access, DID dispatch, DTC persistence, ASIL-B safety wrappers, test coverage. Most teams do this once per project, inconsistently, with no reuse.

Testing it is harder. Running UDS campaigns in CI — across CAN, DoIP, and SOME/IP, against real hardware and simulators, with structured reports and regression tracking — has no good lightweight option. Until now.

// how it works

One YAML file. Three tools. Everything generated.

Author your ECU once. Generate firmware, validation, and a browser playground from the same source of truth.

diagnostics_config.yaml 
# diagnostics_config.yaml
ecu:
  name: body_controller
  transport: doip
  doip:
    logical_address: "0xE400"
    port: 13400

    access: [read]
    sessions: [default, extended]

  - id: "0xF187"
    name: PartNumber

  • Multi-ECU workspace — mix CAN, DoIP, SOME/IP, and SOVD ECUs in one campaign
  • CI-ready — VirtualBus runs in-process, no kernel modules, no Docker required
  • Reads your EDS diagnostics_config.yaml automatically
async with UdsTester("vcan0", rx_id=0x7DF, tx_id=0x7E8) as ecu:
    await ecu.session(Session.EXTENDED)
    await ecu.security_access(level=1)
    vin = await ecu.read_did(0xF190)

// frequently asked

Questions, answered.

Eight things engineers ask before they buy.

Yes. The runtime stack (core/, transport/, config/, platform/) is GPL v2. It includes CAN and DoIP transports, Zephyr and FreeRTOS platform layers, and a full CI test suite. The commercial license covers the codegen templates, tooling, and safety documentation.
No. TestLab works standalone against any UDS ECU — copy testlab_config.yaml, fill in your CAN IDs or DoIP address, and run campaigns. EDS integration is automatic when a diagnostics_config.yaml is present, but it's never required.
Linux SocketCAN, PEAK PCAN USB (Windows + Linux), Kvaser (Windows + Linux), DoIP over TCP, SOME/IP (someipy), and SOVD REST. In CI: VirtualBus and VirtualSomeIpBus run in-process — no kernel modules, no CAN hardware, no Docker required.
No. Cloud generates code and runs simulated tests in the browser. EDS compiles and flashes that code to real hardware. TestLab validates the running firmware on the bench and in CI. Cloud is the evaluation path — engineers who use Cloud and want the full local toolchain purchase EDS Developer.
Yes for EDS and TestLab. The key is cached locally on first activation — no internet calls during builds or test runs. Required for air-gapped automotive development environments. Cloud is SaaS and requires a connection.
The Python library and campaign runner work on Windows. SocketCAN requires Linux, but PCAN, Kvaser, DoIP, SOME/IP, and SOVD work on Windows natively. Cloud works in any browser.
14-day grace period after expiry — runs continue with a renewal warning printed to output. After the grace period, the CLI exits with a license error. Renew and re-activate with one command.
Yes. EDS-toolchain includes arxml_parser.py — AUTOSAR 4.x ECU Extract → diagnostics_config.yaml, no external dependencies. Cloud Pro and Team tiers include drag-and-drop ARXML import in the browser.
