Scalable Diversity-Oriented Decisions and Technologies for Dependable SoPC-Based Safety-Critical Computer Systems and Infrastructures

An approach to development and implementation of multi-version technologies (MVT) for creating dependable system-on-programmable chip (SoPC)-based systems and infrastructures is described. It is based on a set of scalable diversity-oriented decisions selected by use of proposed MVT-graph. This technique is applied for development of nuclear power plants (NPP) instrumentation and control (I&C) platform. The diverse I&C platform RADIY designed, produced and supplied by company Radiy (Ukraine) is described and analyzed. Results of implementation of the suggested decisions and technologies in safety- critical dependable systems and infrastructures of Ukrainian NPPs are analyzed.
