l'IEC 62566-2:2020 énonce des exigences pour atteindre une haute fiabilité dans les "circuits intégrés programmés en HDL" (HPD) destinés aux systèmes d'I&C des centrales nucléaires de puissance réalisant des fonctions de sûreté de catégorie B ou C telles que définies par l'IEC 61226. La programmation des HPD repose sur des langages de description de matériel (HDL) et des outils logiciels associés. Les HPD sont typiquement basés sur des réseaux de portes programmables sur site (FPGA) vierges ou sur des technologies microélectroniques similaires telles que les réseaux logiques programmables (PLD), les réseaux logiques programmables complexes (CPLD), etc. Les circuits intégrés d'usage général tels que les microprocesseurs ne sont pas des HPD. Le présent document énonce des exigences sur: a) un cycle de vie de HPD dédié concernant chaque phase du développement des HPD, notamment la spécification des exigences, la conception, la réalisation, l'intégration et la validation, ainsi que les activités de vérification associées à chacune des phases; b) la planification et les activités complémentaires telles que la modification et la production; c) le choix des composants prédéveloppés, notamment les technologies microélectroniques et les blocs prédéveloppés (PDB); d) les outils utilisés pour concevoir, réaliser et vérifier les HPD.
