IEC 62566的本部分规定了实现高可靠性HDL编程的要求 执行安全功能的核电厂仪控系统用装置（HPD） IEC 61226定义的B类或C类。 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，如可编程逻辑器件（PLD），复杂 可编程逻辑器件（CPLD）等。 通用集成电路，如 微处理器不是HPD。附录B.8提供了许多不同类型的说明 集成电路。购买本文件时可获得的所有当前修订均包含在购买本文件中。

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.All current amendments available at time of purchase are included with the purchase of this document.
