HIL/SIL Testing & Validation
For Automotive, Avionics & UAS Systems

We build end-to-end test pipelines—from restbus, HIL, and SIL simulation through diagnostics and automated reporting to integration into CI/CD environments such as Jenkins or GitLab CI—with clearly measurable KPIs to support data-driven release decisions.

HIL and SIL testing with restbus simulation for ECUs and complex electronic systems
Automated diagnostics, logging, and reporting for reproducible, objectively evaluable test results
CI/CD integration (Jenkins, GitLab CI) and scalable test pipelines for faster, safer release cycles

Our teams combine testing and validation expertise with restbus simulation, diagnostics, automated reporting pipelines, and model-based validation. This makes issues visible early, releases measurable, development cycles shorter, and systems more reliable.

SERVICES

Our Testing & Validation Service

From test case definition to reporting – clearly structured, scalable and auditable.

Our testing services cover the entire validation process for modern ECU and embedded software. We combine model-based analysis, restbus simulation, fault reproduction, and automated reporting pipelines to significantly increase test coverage and reliability. We work with dSPACE, CANoe/CANalyzer, NI PXI, Jenkins/GitLab CI, and Automotive SPICE-compliant processes. For our customers, this means transparent results, reproducible defect patterns, and stable releases—across the full development and validation lifecycle.

Test Strategy & Architecture

Robust test strategies, clear traceability, risk analyses, model-based derivations and complete test architectures for ECU and embedded software. This enables us to improve coverage, stability and auditability.

Automation & Reporting

Automated CI pipelines, KPI dashboards, regression tests, reporting automation, and reproducible artefact exports. For stable releases, shorter cycles, and measurable quality assurance.

HIL/SIL & Rest bus Simulation

Reproducible HIL/SIL tests, rest bus simulation, diagnostic automation, and stable test benches on dSPACE and NI platforms. Ideal for communication, safety functions, and complex integration scenarios.

PRACTICAL EXAMPLE

Real world example: HIL validation IPC

From test case definition to reporting—an excerpt from a real project.

Engineering projects in the E/E domain require transparent processes, reproducible tests, and a robust architecture. Our HIL validation combines model-based development, real-time simulation, and automated test strategies to detect issues early and measurably stabilize releases. Through structured test case definition, clear milestones, and full Automotive SPICE traceability, we deliver verifiable results across the entire V-model lifecycle. Reproducible defect patterns, KPI monitoring, and data-driven analyses accelerate development cycles and increase the reliability of modern ECU and embedded software.

WORKFLOW TESTING & VALIDATION

Testing Pipeline – Continuous Integration & Hardware-in-the-Loop

Automated, reproducible, and release-ready.

Our testing pipeline integrates SIL and HIL environments, restbus simulation, diagnostics, and CI automation into a seamless end-to-end test flow. Issues can be reproduced reliably, artifacts are versioned, and results are delivered transparently to stakeholders. This enables objective release-gate decisions, early risk detection, and significantly shorter test cycles.

Validation Process & Release Flow

From commit through build artifacts, SIL simulation, and restbus to automated reports, we ensure every change is tested reproducibly. KPIs, defect flows, and decision templates support your release approvals on a clear, data-driven basis.

FREQUENTLY ASKED QUESTIONS

FAQ – Testing & Validation

With structured test procedures, reliable KPIs and automated pipelines, we ensure reproducible results and accelerate your releases in the long term.

How do automated regression tests increase release security?

They test every code change reproducibly in HIL/SIL environments and identify errors before they occur in complex integration scenarios. This reduces regression errors and shortens test cycles.
#HIL/SIL #Regression #ReleaseGates

Which tools do you use for test automation?

We combine dSPACE SCALEXIO, NI PXI, CANoe/CANalyzer, Python, LabVIEW, and CI environments such as Jenkins/GitLab CI. This allows test chains to be scaled flexibly and fully automated.
#Tools #dSPACE #Jenkins

How do you ensure reproducibility?

Through versioned residual bus models, deterministic test procedures, stable test benches and complete traceability from requirements to test cases.
#Traceability #Repro #ASPICE

What does a comprehensive testing strategy encompass?

Test design, negative cases, risk assessment, test data management, artefact versioning and clear release criteria.
#Testdesign #Risiken #KPIs

Which KPIs do you use to evaluate releases?

Test coverage, defect reproduction rate, defect flow, stability across test runs, time to go-live, and quality of defect patterns.
#KPIs #Qualität #Reporting

How does testing support ASPICE compliance?

Through defined processes, traceable artefacts and documented test procedures that can be directly integrated into existing ASPICE assessments.
