摘要:
由于强实时性、参与闭环控制、软硬件耦合及可靠性要求高等特点,飞行控制系统嵌入式软件在软件研制、测试及验收阶段往往缺少动态测试环境。本文在仿真测试技术基础上,针对飞行控制系统嵌入式软件的特点与测试需求,进行了基于故障注入技术的仿真测试技术研究,设计了一种实时嵌入式软件仿真测试平台方案。

Abstract:
Because of the characteristics of highly real-time , closed loop controlling ,coupling of software with hardware, and the requirements of reliability ,the embedded software of flight-control computer always runs short of dynamic testing system ,especially in the phases of software developing, software testing ,and acceptance testing . In this paper, a method of simulation testing based on fault injection is put forward, after analyzing the testing characteristics and demand, a blue print is designed as well.
Key words:  Real-time embedded software  Software test  Fault injection  Simulation test
