From architecture to testing, IT Link supports you in designing robust and secure embedded systems.
Our support
We transform your requirements into embedded systems ready for operation. From the scoping phase, we align business objectives with technical constraints (safety, security, latency, power consumption, costs, and applicable standards) to define a clear and measurable scope.
We then define the target architecture: selection of the microcontroller, SoC, or FPGA, bus systems, choice of OS (RTOS, embedded Linux, etc.), function partitioning, and the associated validation plan.
At the end of this phase, you receive a detailed architecture document, a traceable requirements matrix, latency and power consumption budgets, as well as a test plan and a security plan. Project management is driven by concrete indicators: worst-case response time (WCRT), CPU/RAM/Flash margins, estimated battery life, and requirement coverage rates.
We design and build embedded software under real-time and reliability constraints. This covers drivers, BSPs, bootloaders, middleware, and applications, with a focus on code readability, testability, and maintainability within your embedded systems.
Communication stacks are integrated and validated in your specific context: CAN, LIN, Ethernet, IP, MQTT, BLE, Wi-Fi, 4G, 5G, LoRa, and LPWAN. Code quality is based on MISRA and CERT standards, systematic reviews, automated testing, and end-to-end continuous integration.
You receive versioned and reproducible code, operational CI/CD pipelines, static analysis reports, test suites, and design documentation. Performance is tracked throughout the project using objective metrics: test coverage, defects per KLOC, boot time, and CPU/memory usage.
We support you in designing electronics for embedded systems: schematics and PCBs, sensor and actuator integration, and power and battery management. Our teams validate boards for signal integrity and electromagnetic compatibility in a representative environment, using robustness campaigns tailored to the context.
You receive a complete package including schematics, routing, bill of materials, manufacturing files, and validation procedures. Acceptance criteria focus on battery life in target conditions, power efficiency, and success rates in SI and EMC testing.
We set up and configure real-time systems on FreeRTOS, Zephyr, ThreadX, QNX, or Linux. Scheduling, latency profiles, and I/O optimization are driven by traces and micro-benchmarks.
When appropriate, we design hybrid architectures combining RTOS and Linux or AUTOSAR Classic and Adaptive to reconcile determinism with advanced services.
Performance is documented in an actionable format with latency profiles, execution traces, and detailed real-time configuration. Tracked indicators include jitter, deadline compliance, interrupt latency, and I/O throughput.
Security is integrated from the architectural level. We deploy secure boot, secret storage using secure elements or TPM, signed OTA updates, system hardening, end-to-end encryption, key management, and threat modeling.
You receive the SBOM, key policies, a CVE remediation plan, and penetration testing reports. Your security posture is measured by observable facts: vulnerabilities fixed per version, success rates of signed OTA deployments, and pentest results.
We guarantee complete and reliable validation of your systems. Every stage is covered: unit testing, integration, non-regression, real-time performance, and robustness. Our advanced methods, including Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL), are reinforced by fault injection and coverage analysis to secure your development process.
We prepare all the compliance documentation required for your sector, whether in automotive, rail, medical, aeronautics, space, or general industry.
You benefit from a clear validation strategy, structured test plans, and actionable reports designed to accelerate your certification cycles and reduce risk.
Monitoring is based on shared, transparent metrics: test success rates, requirement traceability, and validation cycle times, ensuring efficient project management without surprises.
We deploy multi-platform CI/CD pipelines that guarantee reproducible builds and versioned artifacts. During the operation and maintenance phase (MCO), we provide proactive monitoring, security patching, backports, obsolescence management, and secure, signed OTA updates.
You gain access to industrialized CI/CD pipelines, a comprehensive SBOM, tailored versioning policies, operational runbooks, and an MCO dashboard enriched with vulnerability and compliance reports.
System reliability is measured through key performance indicators: MTBF, MTTR, OTA update success rates, CVE remediation time, regression rates, and patch coverage across your entire fleet.
We strengthen your team's expertise through targeted workshops on real-time computing, software engineering, and cybersecurity, as well as pair-programming sessions and practical operation and maintenance guides. Knowledge transfer includes:
- structured training materials,
- a clear handover plan,
- a best-practices repository to ensure continuity.
Efficiency is measured by the autonomy gained by your teams, the seamless adoption of methods, and stakeholder satisfaction.

Industries Served
Each embedded system is custom-designed and developed to meet your specific technical, regulatory, and operational requirements. The examples above illustrate typical project scopes and do not represent the full extent of our capabilities.
Aerospace and Defense
Avionics and space programs require robust, traceable embedded systems. Our scope covers onboard computers, payloads, and TM/TC chains, hardened software development, latency measurement, and deterministic processing, as well as integration with ground stations. Development and testing evidence is tailored to the specific context and standards, including DO-178C, DO-254, and ECSS, while accounting for environmental and power constraints.
Automotive
In the automotive sector, embedded systems range from driver assistance control units to connected vehicles. Depending on the requirements, this may include sensor fusion for ADAS, battery management and power electronics, CAN, LIN, and Ethernet communication gateways with secure software updates, as well as onboard diagnostics and telemetry. Architectures and software are tailored on a case-by-case basis for real-time determinism, cybersecurity, and functional safety, in compliance with standards such as ISO 26262 and AUTOSAR.
Energy
For smart grids and distributed asset integration, embedded systems address metering, local control, and edge computing. Typical examples include network sensors and secure RTUs for SCADA, low-power connected meters and devices using LPWAN, and edge gateways that aggregate data, apply local rules, and ensure signed updates. The architecture prioritizes energy autonomy, robustness, monitoring, and operational security, in line with industry standards such as IEC 62443.
Rail
Onboard rolling stock and infrastructure, embedded systems support traction, signaling, event recording, telemetry, and onboard IP architectures. HIL and SIL test chains, requirements-to-test traceability, and documentation preparation are structured to facilitate qualification according to EN 50126, EN 50128, and EN 50129, with a constant focus on reliability and availability.
