“…The approach to assessment of diversity level and MVS safety is based on the four basic procedures of analysis and evaluation. The first procedure implements D-1,2-analysis, procedures form the second to the forth implement D-3-analysis [11] . a. analysis of I&C specification and requirements to system, definition of system safety class; requirements to diversity (necessary for diversity application); b. analysis of I&C design and development process, that involves activities: (b1) identification of MVS types: which of the subsystems are FPGA-based and which are software and microprocessorbased; (b2) identification of product diversity; for FPGA-based MVSs: manufacturer of chips; FPGA technology; FPGA families; FPGA chips, languages; tools, etc); (b3) identification of process diversity kinds.…”
