Critical Software has expertise in testing, verifying and validating safety-critical and mission-critical embedded systems, from RAMS analysis to certification. Runtime verification (RV) is a more lightweight method aimed at verifying that a spe- cific execution of a system satisfies or violates a given critical property [5]. Runtime ver- ification can provide a formal analysis while avoiding many of the pitfalls that traditional model-based methods have such as state space explosion and model abstractions. Second, to prevent attacks against the control logic used in controllers, we provide a runtime verification solution by leveraging the physical and control invariants of the system. Control logic is a part of a software program that controls the operations of the program. The number of states that a system can be is represented by state variables.15 oct. 2008 ...

The nature of safety-critical systems and software; Safety management: hazards, risks, risk assessment, and reduction, software reliability; Finite-state machine models and predicates; Software engineering lifecycles, processes and activities, the role of verification and validation. Specifying control systemsA prototype run-time monitoring approach for flight-critical systems has been developed and demonstrated in batch and real-time simulations for a UAV system and it is shown that without a runtime V&V system, the vehicle either fails to accomplish the mission, or worse, is lost due to ensuing instability. In this paper, we address the issues of safety-critical software verification and testing that are key requirements for achieving DO-178C and DO-331 regulatory compliance for airborne systems. Formal verification and testing are considered two different activities within airborne standards and they belongThe main objective of the GPR tests was to verify the absence of possible cavities beneath the ground surface that could undermine the strength of the surface under heavy loadings. To that effect, a multi-frequency ground-coupled GPR system was used. This radar system can simultaneously collect data at both the frequencies of 600 MHz and 1600 MHz. convert video to rtsp stream The competency of tradespersons working on safety critical systems should be assessed and verified to ensure work is carried out correctly and does not pose a risk to the operation of the vehicle. 4. Following work on safety critical systems, the system should be inspected and tested to verify that it is safe to operate, before re-entering service.Even traditionally non-critical systems are becoming safety- or mission-critical due to the addition of connectivity, complex au-tonomy and software reliant control (e.g., X-by-wire [2].

Verification by an ICP is required for new and existing facilities, to ensure SCEs remain effective and reliable throughout their service life. In order to verify that SCEs are suitable and will remain effective and reliable, an ICP must carry out an independent review which may include examination, testing, and review of evidence (as appropriate).Phoronix: Linux 6.0 Adding Run-Time Verification For Running On Safety Critical Systems Another big ticket feature has made it for the Linux 6.0 kernel: the Runtime Verification infrastructure for running Linux on safety-critical systems...Based on standards for writing “good” C code, this paper proposes strong memory safety as the least restrictive formal definition of memory safety amenable for runtime verification.

Advancing aerospace and automotive technologies require complex designs of hardware and RTOS. So, verification of platform software per safety-critical standards (i.e. DO 178B/C [2]) is significant, involving more resources in terms of cost and time. Verification of platform software components needs a mixture of different approaches [1]. High-availability systems today strive to be up and running 99.999% of the time (the so-called "five nines availability"), equivalent to a total of about five minutes down time per year. On the other hand, safety-critical systems don't always strive to maximize uptime. civil rights activists in spanish Formal mathematical methods of software development have been used for safety critical systems. Cost of verification and validation are usually very high for such systems. More than 50% of the total system goes to development cost.
