摘要:: 航空机载电子设备复杂度的不断提高，对于机载电子设备的基础——航空集成电路功能及性能的要求也不断提高，高集成度、高复杂度、高性能、低功耗、小型化已经成为了航空集成电路发展的必然趋势，而传统的设计和管理手段已经不能满足航空集成电路高安全性应用需求。探索并建立一个机载领域集成电路设计过程正确性保障体系，已成为迫切需要。DO-254标准代表了工业界、适航当局、机载领域硬件设计人员在内的大多数专家的一致意见，是机载电子硬件开发保证过程最好的实践经验的集合。文中将从集成电路硬件角度出发，研究并借鉴DO一254标准的需求管理和过程保证方法，将好的管理策略运用到集成电路系统设计和前端设计过程中，以提高航空集成电路硬件设计的安全等级，降低航空集成电路开发风险

Abstract:: High complexity of integrated, high performance, low power dissipation and miniaturization have been considered as the inevitable tendency in aviation-IC while the requirement of function and performance had to be enhanced higher with increasingly complexity of aviation electronic devices. However, traditional design and management method could not satisfy developing demand of safety in aviation -integrated-circuit design field. It is definitely necessary to build a correctly and stably ＂procedure support system＂ for IC design in airborne implementation field. It is obviously that DO-254 standard could not doubt represent opinion of huge amount of experts in industry ,airworthy department and IC designers of airborne field which DO-254 standard could be considered as the best and reliable standard in hardware design procedure of airborne implementation field. It focuses on research on requirement management and support process method of ＂DO-254 standard＂ standing on the view of hardware design, and then implement best manage strategy into system and front-end design in IC field in order to enhance safety level and decrease developing risk as possible as it could
