SERVICES

Software Engineering – End-to-End

Focus on automotive, aerospace, defence.

From embedded development through verification to data & simulation. Clearly structured, auditable, and scalable.
Our engineering services cover the full end-to-end cycle of modern E/E development: from AUTOSAR-based ECU software and HIL testing with dSPACE/NI infrastructures to telematics functions, FOTA rollback strategies, ADAS data pipelines, and open-/closed-loop simulations.
We combine ISO 26262-compliant processes, Automotive SPICE-oriented workflows, and DevOps toolchains (Jenkins, GitLab CI, CANalyzer/CANoe) to ensure reproducible results, high test coverage, and transparent traceability down to the test case level.
Our teams work in V-model or Agile/Scrum setups and integrate seamlessly into existing development, quality, and compliance structures—including reporting, KPIs, documentation, and audit-ready deliverables.

PRACTICAL EXAMPLE

Real world example: ECU software & E/E engineering

FROM ARCHITECTURE TO RELEASE – AN INSIDE LOOK AT AN E/E PROJECT

Engineering projects in the E/E domain require clear architectures, consistent processes, and auditable results. Our E/E development combines AUTOSAR configuration, model-based development, and embedded software implementation to realize robust and scalable ECU functions. With transparent release gates, automated toolchains, and full traceability, we ensure reproducible outcomes across the entire development lifecycle.

Through structured architecture definition, model-based functions, deterministic build processes, and automated integration testing, we achieve measurable quality improvements and stable releases for safety-critical applications. Our end-to-end Automotive SPICE workflows provide traceability, reduce defect patterns, and significantly accelerate development cycles for modern ECU and embedded software.

Initial situation

New E/E architecture with multiple control units, bus systems and wiring harness variants. AUTOSAR-based ECU software with diagnostic, communication and safety functions needed to be integrated and validated using HIL/SIL tests. We supported the customer with E/E architecture, wiring harness design, ECU software development and testing.

WORKFLOW ELECTRONIC ELECTRICAL ENGINEERING

Workflow (EE) – Agile/V-Model XT and ASPICE at a glance

Structured steps and clear guidelines for modern E/E development – from concept, architecture and implementation to testing, traceability and reporting.

Development process for embedded software and E/E systems

Agile sprints, V-Model XT, and Automotive SPICE in one end-to-end development process.

Our development process is based on V-Model XT as a modern, adaptable process platform. Requirements, architecture, design, and tests are clearly structured and linked to defined milestones—ideal for complex, safety-critical embedded software and E/E systems. In agile sprints, our teams deliver working increments and iteratively refine the backlog and architecture. Automotive SPICE-oriented workflows ensure that roles, deliverables, and KPIs are clearly defined and consistently traceable—down to the individual test case.

Agile sprints: incremental software development with a clearly prioritized backlog and regular feature deliveries
V-Model XT: traceability from requirements through architecture and design to testing
Automotive SPICE: system and software engineering processes (SYS/SWE), project management (MAN.3), KPIs, and end-to-end traceability

FREQUENTLY ASKED QUESTIONS

FAQ – E/E Engineering

With clear E/E processes, model-based development and automated testing, we increase the reliability, stability and release security of your systems.

How does E/E engineering support the development of modern ECU software?

Our E/E engineering processes combine architecture, implementation and testing throughout the entire lifecycle of ECU software. This includes AUTOSAR Classic/Adaptive, model-based development with Simulink/Stateflow, diagnostics (UDS/J1939) as well as bootloader and flashing processes. Through clear release gates, automated test chains and complete traceability, we ensure that software is stable, auditable and suitable for safety-related systems.
#ECU Software #AUTOSAR & Development Processes

What standards and norms do you take into account in the development process?

Our projects are based on common automotive and avionics standards such as ASPICE, ISO 26262, TISAX and specific network protocols (UDS, DoIP, ARINC 429/664). We integrate these standards directly into the toolchains – from DOORS and Polarion to GitLab CI and Jenkins. This ensures that development and testing phases meet all requirements for security, traceability and maturity.
#ASPICE #ISO 26262 #TISAX & Compliance

How is HIL/SIL used in your workflow?

Hardware-in-the-loop (HIL) and software-in-the-loop (SIL) enable early fault detection, reproducible testing, and automated regression testing. We work with dSPACE SCALEXIO, NI PXI/CompactRIO and CANalyzer/CANoe to transparently increase test coverage, fault reproducibility and KPIs. Simulation, residual bus models and fault injection complement validation and make complex scenarios reproducible in the laboratory.
#HIL #SIL #dSPACE & Test Automation

How do you support companies in setting up a modern toolchain?

We integrate CI/CD processes with Jenkins and GitLab CI, requirements tools such as DOORS, Polarion or Jama, and validation tools such as CANoe, dSPACE and Python/PyTest. This creates a continuous development flow that links architecture, implementation, testing, KPIs and reporting. The result is stable releases, shorter cycles and auditable artefacts.
#CI/CD #Toolchain integration & traceability

How do you ensure quality and measurability in E/E engineering?

We ensure quality through automated test chains, KPI dashboards, a clear definition of done, ASPICE-compliant roles and structured test case derivations. We measure defect rates, test coverage, throughput time, reproducibility and release stability. This allows decisions to be made based on facts and significantly reduces the risk of technical regressions.
#KPI-Driven Development & Quality Assurance

What advantages does your end-to-end workflow offer customers?

The combination of architecture, development, simulation, testing and documentation creates a fully integrated process. Customers benefit from faster iterations, stable releases, better test coverage and reduced risk of errors. At the same time, the approach can be flexibly adapted to agile sprints or classic V-model structures and seamlessly integrated into existing organisations.
