摘要： 飞行控制软件主要采用Host-Target的仿真测试模式，并基于插桩技术实现覆盖测试。针对采用传统的程序插桩技术，往往会大量增加程序运行时间，降低程序的实时性甚至导致软件失效的问题，通过分析插桩在程序仿真测试中对程序各阶段执行时间和程序实时性的影响，提出一种优化桩信息传输过程的插桩测试方法。实验结果表明了该方法的有效性。

Abstract: Flight-control software adopts Host-Target simulation test mode and achieves coverage test based on instrumentation. Traditional program instrumentation can increase the executing time greatly and influence the real-time performance then even cause software failure. This paper analyzes the influence of instrumentation in different process of the simulation software test through some experiments. And an optimal method of software test process to the probe information transmission is presented. Experimental results show this method is effective and feasible.

Key words: flight-control software, coverage test, instrumentation
