Abstract

Diversity and subdiversity-oriented systems applied in safety critical industry systems are analyzed through the use of the classification scheme described in standard NUREG7007. This classification is specified considering diversity of hardware and FPGA designs. In particular, diversity of hard logic and soft processors, interfaces and buses, self-diagnostics means, etc... are described. Impact of hardware/FPGA diversity on safety of Instrumentation and Control systems (I&Cs) are analyzed. The technique for selecting such diversity is presented.
