Software for vehicle network development and test

Analysis, simulation, diagnostics and test for vehicle buses. Fully usable offline.

Arnodiqa is a development and test tool for CAN, CAN FD, CAN XL, LIN and J1939. It records and decodes bus traffic, simulates rest buses and ECUs, runs diagnostics and flashing, and automates tests. It is used by engineers at OEMs, suppliers and test labs, including in environments without an internet connection.

Request evaluation Product overview

No telemetry, no online activation
Perpetual licence
Desktop application and CLI

Trace window: decoded CAN and CAN FD traffic on three channels, with the Write window below

Trace window with decoded CAN and CAN FD traffic on three channels. Below it, the Write window.

Applications

One engine for the desktop and the command line

All features

Analysis

View bus traffic live or from BLF, ASC and MF4 logs. Decode with DBC or ARXML, then filter, log and export.

Analysis

Rest-bus simulation

Interaction layer from DBC, ARXML or LDF with send types, cycle times, alive counters, E2E and SecOC.

Simulation

Diagnostics and flashing

ISO-TP, UDS, OBD-II, DoIP and J1939, symbolic with ODX/PDX. ECU simulation and flashing via UDS.

Diagnostics

Test and CI

Test modules in CAPL, test units in YAML, reports as HTML, JSON and JUnit. The headless CLI returns an exit code based on the verdict.

Test

Air-gapped operation

Built for isolated labs

Test benches, HIL rooms and security labs are often deliberately disconnected from the internet. Arnodiqa makes no network connections and collects no telemetry. Installation, licensing and documentation work without internet access.

Licence	Signed licence file, checked locally. No activation, no phone-home.
Installation	Offline Windows installer. SBOM and third-party notices with every release.
Hardware key	Not required.

All features

Users

For development and validation teams

OEMs

Network integration, rest-bus simulation of the vehicle and validation of supplier ECUs.

Suppliers

ECU development against the OEM database, diagnostics, flashing and regression tests in CI.

Test labs

Test benches and HIL setups, often on networks without internet access.

Engineering firms
