Automotive Testing Services: HIL, ADAS, Diagnostics and Cybersecurity

Stalwart Innovations delivers automotive testing services from Bengaluru, India: MIL, SIL and HIL testing of ECU software, scenario-based ADAS testing with ASAM OpenSCENARIO, CAN FD, Automotive Ethernet and UDS diagnostic tests, ISO 26262 verification evidence, and UNECE R155 and R156 cybersecurity and OTA update testing, run as projects, managed teams or engineers in your lab.

What we deliver

Test strategy and plans

Test level per requirement across MIL, SIL, HIL and vehicle, coverage targets by ASIL, and ASPICE SWE.4 to SWE.6 and SYS.4 to SYS.5 work products.

MIL, SIL and HIL test suites

Back-to-back MIL/SIL tests, virtual ECU regression in CI and HIL suites with restbus and fault injection. More on HIL/SIL testing.

ADAS scenario catalogues

Logical and concrete scenarios in ASAM OpenSCENARIO with OpenDRIVE road networks, parameter sweeps and Euro NCAP 2026 test cases for SIL and HIL execution.

Network and diagnostic tests

CAN FD, LIN and Automotive Ethernet (SOME/IP, DoIP) communication tests, UDS (ISO 14229) services, DTC handling, network management and gateway routing.

Safety verification evidence

Requirements-based tests, fault-injection results and structural coverage that feed the ISO 26262 safety case and SOTIF validation.

Cybersecurity and OTA tests

Security function tests, fuzzing and penetration tests for R155, and update tests for R156: interrupted downloads, rollback, version checks and RXSWIN records.

How we work

01

Review requirements

Check testability, allocate each requirement to MIL, SIL, HIL or vehicle, and agree pass criteria with your system and safety leads.

02

Set up environments

Configure models, virtual ECUs, restbus and scenario tooling, or adapt your existing HIL rigs and CI runners.

03

Specify and automate

Write test specifications, implement them in ecu.test, vTESTstudio, CANoe or Python, and peer-review them before execution.

04

Execute and triage

Run campaigns per software release, analyse failures with developers and track defects to closure in your ALM.

05

Report for audit

Publish traced results and coverage in the form your ASPICE assessor, safety assessor or type-approval authority expects.

Where this fits

This page covers automotive testing as a whole. HIL test bench setup covers specifying and commissioning rigs, cybersecurity testing covers R155 fuzzing and penetration testing in depth, and test automation covers frameworks and CI. ECUs under test often come from our AUTOSAR, ADAS and sensor fusion and EV and BMS work, and the wider picture is on the testing & validation hub.

Frequently asked questions

What testing does UNECE R155 type approval require?

R155 requires the manufacturer to show, per vehicle type, that risks identified in the risk assessment are mitigated and that the measures have been tested for effectiveness. In practice this means a cybersecurity test specification, functional tests of security controls, fuzzing and penetration testing of exposed interfaces, and findings tracked to closure. Suppliers provide component evidence under ISO/SAE 21434 that the OEM uses in its type-approval file.

How do Euro NCAP 2026 changes affect ADAS validation?

Euro NCAP's 2026 protocols are its biggest overhaul since 2009, adding ADAS robustness, HMI and driver-monitoring assessments. Test-equipment vendor AB Dynamics reports more than 1,200 ADAS test variations, roughly double the previous cycle. That volume pushes most variants into SIL and HIL scenario testing, with track tests kept for confirmation, so scenario catalogues and simulation capacity need planning early.

Which standards define scenario-based ADAS testing?

ISO 34502:2022 sets out a scenario-based safety evaluation framework for automated driving systems on limited-access highways. ASAM OpenSCENARIO describes the dynamic content of scenarios and ASAM OpenDRIVE the road network, so the same scenario can run in different simulators. ISO 21448 (SOTIF) drives the search for triggering conditions, and UNECE R171 sets requirements for driver control assistance systems.

What structural coverage does ISO 26262 expect at unit level?

ISO 26262-6 highly recommends statement coverage for ASIL A and B, branch coverage for ASIL B to D and MC/DC for ASIL D. Coverage is measured on requirements-based tests, and gaps are analysed: missing tests are added and unreachable or defensive code is justified. VectorCAST, Tessy or LDRA typically produce the reports.

How is OTA update testing done for UNECE R156?

Tests cover the update chain end to end: package signing and verification, preconditions such as battery and vehicle state, interrupted downloads and installs, rollback to the previous version, user notification and correct update of RXSWIN records. Tests run first on HIL or bench setups with the backend simulated, then on vehicles for campaign-level confirmation.

Do you work on our HIL rigs or provide your own?

Usually on yours, because a HIL configuration is specific to the ECU, I/O and vehicle network. Engineers configure, extend and automate dSPACE, NI and Vector benches, on site or remotely where your IT policy allows. If you need a new rig, HIL test bench setup covers specification, integration and commissioning.

Can we hire automotive test engineers instead?

Yes. We recruit HIL, ADAS validation, diagnostics and test automation engineers on contract, contract-to-hire or permanent terms. See automotive engineers and hire test engineers for how candidates are screened on hands-on tool and standards experience.
