Verification & Validation

Critical systems are distinct in that they require a significant amount of Verification and Validation (V&V) activities in order to comply with industry certification requirements.

In fact, V&V can easily account for the biggest chunk of effort in the development of safety-critical systems. In industries with the strictest regulatory requirements, V&V can amount to 70% of the total development effort.


We have an international pedigree providing V&V services for some of the world’s leading institutions in demanding industries like aerospace, space, defence and transport. Our extensive knowledge of embedded systems and the world’s most important safety standards mean we are able to assist organisations across the entire development life cycle. Our V&V experts are supported by our own multi-purpose Software Validation Facilities which add flexibility to our services by supporting automated hardware, model and software-in-the-loop test environments according to the most stringent industry standards, including DO-178B/C Level A. Through our world-class facilities, we are able to re-execute entire test campaigns at any point during development stages, delivering effective non-regression verification whenever the system subject to testing is modified.


The safety standards we support include ARP-4754/4761, DO-178B/C, DO-254, EN 50126/8/9, IEC 61508, ISO 26262, IEC 62304, ECSS Series and many more besides.


Our services span the full stack of embedded systems, software, FPGA/ASIC/CPLD and integrated equipment:

  • Planning of V&V activities to ensure conformity with safety standards and certification regulations
  • Independent V&V of system requirements and design
  • Formal verification of source code, unit and integration testing
  • V&V of custom logic designs (ASIC, FPGA and CPLD)
  • Hardware and software integration testing, as well as testing of integrated embedded systems
  • Recording of V&V evidence required for certification
  • Automated testing with software-in-the-loop (SIL), model-in-the-loop (MIL) and hardware-in-the-loop (HIL)
  • Development and tailoring of automated test facilities for embedded software and hardware systems
  • Test facilities and services for equipment acceptance and homologation testing
