BS EN IEC 62566-2:2020

1   Scope This part of IEC 62566 provides requirements for achieving highly reliable HDL -Programmed Devices ( HPDs ), for use in I&C systems of nuclear power plants performing functions of safety category B or C as defined by IEC 61226. The programming of HPDs relies on Hardware Description Languages ( HDL ) and related software tools. They are typically based on blank Field Programmable Gate Arrays ( FPGAs ) or similar micro-electronic technologies such as Programmable Logic Devices ( PLD ), Complex Programmable Logic Devices (CPLDs), etc. General purpose integrated circuits such as microprocessors are not HPDs . Annex B.8 provides descriptions of a number of different types of integrated circuits. This document provides requirements on:

a) a dedicated HPD life-cycle addressing each phase of the development of HPDs , including specification of requirements, design, implementation, integration and validation, as well as verification activities associated with each phase,

b) planning and complementary activities such as modification and production,
