From architecture to tests, IT Link supports you in the design of robust and secure embedded systems.
We transform your requirements into embedded systems ready for operation. Right from the start, we align business objectives and technical constraints (safety, security, security, latency, energy consumption, costs and applicable standards) in order to define a clear and measurable perimeter.
We then define the target architecture: choice of microcontroller, SoC or FPGA, buses, choice of OS (RT OS, embedded Linux...), partitioning of functions and associated validation plan.
At the end of this phase, you receive a substantiated architecture file, a traceable requirements matrix, latency and consumption budgets, as well as a test plan and a security plan. Management is based on concrete indicators: worst-case latency (WCRT), CPU, RAM and Flash margins, estimated battery life and requirements coverage rate.
We design and produce embedded software under the constraints of real time and reliability. This covers drivers, BSPs, bootloaders, middleware, and applications, with a particular focus on code readability, testability, and maintainability within your embedded systems.
Communication stacks are integrated and validated in your context: CAN, LIN, Ethernet, Ethernet, IP, MQTT, BLE, Wi-Fi, 4G, 5G, 5G, LoRa, and LPWAN. Code quality is based on MISRA and CERT rules, systematic reviews, automated tests, and continuous end-to-end integration.
You receive versioned and repeatable code, operational CI/CD pipelines, static analysis reports, test sets, and design documentation. Performance is monitored throughout the project with objective indicators: test coverage, faults by KLOC, startup time, CPU and memory usage.
We support you in the design of electronics for embedded systems: diagrams and PCBs, integration of sensors and actuators, energy and autonomy management. Our teams validate the cards in terms of signal integrity and electromagnetic compatibility in a representative environment, with robustness campaigns adapted to the context.
You receive a complete file including drawings, routing, bill of materials, manufacturing files and validation procedures. Acceptance criteria include autonomy under target conditions, power efficiency and the success rate in SI and EMC tests.
We set up and configure real-time systems on FreeRTOS, Zephyr, ThreadX, QNX or Linux. Scheduling, latency profiles and input-output optimization are driven by traces and micro-benchmarks.
When relevant, we design hybrid architectures combining RTOS and Linux or AUTOSAR Classic and Adaptive in order to reconcile determinism and services.
Performance is documented in an actionable manner with latency profiles, execution traces, and detailed real-time configuration. The indicators monitored include jitter, compliance with deadlines, interruption times and input-output throughput.
Security is integrated right from the architecture. We deploy secure boot, secure element secret storage or TPM, signed OTA updates, hardening, end-to-end encryption, key management, and threat modeling.
You have the SBOM, key policies, a CVE remediation plan, and penetration test reports. The security posture is measured by observable facts: vulnerabilities fixed by version, success rate of signed OTA deployments and pentest results.
We guarantee a complete and reliable validation of your systems. Each stage is covered: unit testing, integration, non-regression, real time, and robustness. Our advanced methods, including HIL (Hardware-in-the-Loop) and SIL (Software-in-the-Loop), are reinforced by fault injection and coverage measurement to secure your developments.
We prepare for you all the compliance files required in your sector, whether it is automotive, rail, medical, aeronautical, space or even industry.
You benefit from a clear validation strategy, structured test plans, and actionable reports designed to speed up your certification cycles and reduce your risks.
Monitoring is based on shared and transparent indicators: test success rate, traceability of requirements and validation cycle time, for effective and unsurprising project management.
We deploy multi-platform CI/CD chains guaranteeing repeatable builds and versioned artifacts. During the operation and maintenance phase in operational conditions (MCO), we ensure proactive supervision, the application of security patches, backports, obsolescence management as well as secure and signed OTA updates.
You have industrialized CI/CD pipelines, a comprehensive SBOM, adapted version policies, operational runbooks, and an MCO dashboard enriched with vulnerability and compliance reports.
The reliability of your systems is measured through key indicators: MTBF, MTTR, success rate of OTA updates, CVE remediation time, regression rate and patch coverage across the entire fleet.
We strengthen the expertise of your teams through targeted workshops in real-time computing, software engineering and cybersecurity, peer programming sessions and practical operating and maintenance guides.
Skills transfer includes:
Efficiency is measured by the autonomy gained by your teams, the smooth adoption of methods and the satisfaction of stakeholders.
Each embedded system is custom designed and developed to meet your technical, regulatory and operational context. The examples above illustrate typical perimeters and do not exhaust our field of intervention.
Worst-case budgets by layer (ISR, drivers, drivers, middleware, application), HIL/SIL benches, reproducible validation protocols. The objectives are integrated into the acceptance criteria.
Yes. Partitioning (hard functions under RTOS, services under Linux/Autosar Adaptive), secure IPC, memory isolation and graceful reboot to maintain reliability.
Traceability of requirements→design→tests, formal proofreading, adapted coverage (up to MC/DC depending on field), configuration management and audit-ready files.
Secure boot, secrets in SE/TPM, signed OTA, OTA, SBOM, CVE management, hardening, intrusion tests; threat modeling from the architecture of your embedded systems.
Static analysis reports (MISRA/CERT), coverage, unit/integration test results, real-time logs, scripts, and test data with CI/CD.
Contract clauses, private repositories, access control, artifact encryption, logging, retention policies. The IP (code, models, diagrams) is delivered according to the contract.
Yes: LTS, security backports, CVE monitoring, component obsolescence monitoring, reliability indicators.
