摘要: 介绍执行机构驱动单元软件(ADU)的功能设计和时序设计.从总线消息时序冲突、临界资源访问冲突等方面分析软件外部接口时序设计约束、内部接口时序设计约束的满足性,对时序设计有效性进行验证.软件可靠性设计方面,采用软件失效模式及影响分析(SFMEA)方法识别软件中的关键变量/器件,对其采取单粒子效应防护措施,并验证了措施的有效性.

关键词: 执行机构驱动单元, 时序, 1553B, 中断, 单粒子

Abstract: The design procedure of ADU(actuator drive unit)software is introduced. The outer and inner time sequence restriction, such as 1553B message order and critical resource accessing order, are analyzed. The valid confirmation is presented. On software reliability, the key variables or system parts are recognized by SFMEA(software failure modes and effects analysis). Protection of singleevent upset of them is given. The validation of protection measure is validated.

Key words: actuator drive unit, time sequence, 1553B, interrupt, SEU
