Automotive Diagnostics Testing & Simulation
UDS, OBD-II, and DoIP — import, simulate, test, send, and decode diagnostics in one workbench, from SIL to HIL.
What We Provide for Diagnostics
Alefbits brings the full diagnostic workflow — import, simulate, send, test, and decode — into a single workbench, driven by your existing ODX, CDD, PDX, and DEXT databases.
Diagnostic Simulation & ECU/Tester Roles
Receive reassembled diagnostic messages in Python behaviors and respond as the simulated ECU — positive responses or NRCs, OBD-II PID emulation — or act as the tester for ECU-to-ECU diagnostic chains.
Diagnostic Sender
An engineering tester for ECU bring-up: navigate the UDS catalog and OBD-II PIDs, build requests, monitor DTCs, perform SecurityAccess, over ISO-TP (CAN) or DoIP (Ethernet).
Diagnostic Trace Decoding
Every diagnostic frame named: ISO-TP reassembly, UDS service and NRC names, OBD-II mode/PID decoding with units, and DoIP dissection with full multi-frame correlation.
Database-Driven Catalog
Import ODX, CDD, PDX, and DEXT into one unified catalog that binds to the right ECU automatically, generating typed Python helpers and one-click diagnostic test matrices.
Powered by UCAN Studio
Our diagnostics workflow is built on UCAN Studio — explore the platform and its core capability areas.
UCAN Studio
The automotive software engineering platform behind our diagnostics — the Diagnostic Sender, simulation behaviors, automated tests, and full-stack trace decoding in one workbench.
Our Services
Diagnostic stack configuration, integration, and validation for UDS, OBD-II, and DoIP.
Diagnostic Stack Configuration
Configuration and tailoring of the diagnostic stack — UDS (ISO 14229), ISO-TP, and DoIP — to your ECU’s diagnostic design.
Diagnostic Stack Integration
Integration of the diagnostic stack into your ECU and platform software, aligned to your diagnostic databases and topology.
Diagnostic Validation
Validation of ECU diagnostic features — request/response correctness, NRC handling, DTC management, and OBD-II emissions — using UCAN Studio.
