Abstract

Dependability and Safety of instrumentation and control critical systems depend on characteristics of quality of the software, performing critical functions. Latent faults (faults undetected during testing or verification) of the critical software are factors of the risk of system failure. The independent verification of the critical software, which confirms a performance of declared functions and estimates a probability of latent faults existence, is the necessary condition according to the regulative requirements for different areas (IAEA, ESA and so on). From this point of view, the main problems are: the reliability of independent verification; assessment of latent faults probability; completeness of test coverage for the critical software and as result the quantitative assessment of functional safety. Considered is the development and implementation of the advanced methodology of proven independent verification on the base of the software sourcecode static analysis. Methodology is aimed at the assessment of the semantic, intervalprecision, logic and others invariants ((software properties invariable during the life cycle)) of critical software and also generation and presentations of results of assessment conformity to requirements of standards and project specifications.
