IEC 62566-2:20 20提供了实现高可靠性HDL编程设备（HPD）的要求，用于执行IEC 61226定义的安全类别B或C的功能的核电厂的I&C系统。 HPDs的编程依赖于硬件描述语言（HDL）和相关的软件工具。它们通常基于空白现场可编程门阵列(FPGA)或类似的微电子技术，例如可编程逻辑器件(PLD)、复杂可编程逻辑器件(CPLD)等。诸如微处理器的通用集成电路不是HPD。 本文件提供了以下要求: a)专门的HPD生命周期，处理HPD开发的每个阶段，包括需求规范、设计、实施、集成和验证，以及与每个阶段相关的验证活动， b)规划和补充活动，如改装和生产， c)预先开发的组件的选择。这包括微电子技术和预开发模块， d)用于设计、实施和验证HPD的工具。

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.
