IEC 62566-2:2020 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. 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, c) selection of pre-developed components. This includes micro-electronic technologies and Pre-Developed Blocks (PDBs), d) tools used to design, implement and verify HPDs. lIEC 62566-2:2020 enonce des exigences pour atteindre une haute fiabilite dans les "circuits integres programmes en HDL" (HPD) destines aux systemes dI&C des centrales nucleaires de puissance realisant des fonctions de surete de categorie B ou C telles que definies par lIEC 61226. La programmation des HPD repose sur des langages de description de materiel (HDL) et des outils logiciels associes. Les HPD sont typiquement bases sur des reseaux de portes programmables sur site (FPGA) vierges ou sur des technologies microelectroniques similaires telles que les reseaux logiques programmables (PLD), les reseaux logiques programmables complexes (CPLD), etc. Les circuits integres dusage general tels que les microprocesseurs ne sont pas des HPD. Le present document enonce des exigences sur: a) un cycle de vie de HPD dedie concernant chaque phase du developpement des HPD, notamment la specification des exigences, la conception, la realisation, lintegration et la validation, ainsi que les activites de verification associees a chacune des phases; b) la planification et les activites complementaires telles que la modification et la production; c) le choix des composants predeveloppes, notamment les technologies microelectroniques et les blocs predeveloppes (PDB); d) les outils utilises pour concevoir, realiser et verifier les HPD.
