| 摘 要： | 航天嵌入式软件是航天型号任务成败的关键之一.航天嵌入式软件是一种周期性、多模式的软件.软件的每个模式表示系统处于一定的状态,并进行相应的复杂计算.因此,提出了一种名为SPARDL的形式化建模方法.为了满足型号应用的需求,对这一方法进行了若干改进.为了表达航天器的时序性质,提出了一种基于区间逻辑的性质规范语言.为了支持工业应用,还设计了代码生成方法.这一建模方法已在航天工业领域得到了应用.

| Abstract: | The success of aerospace depends on the correctness of aerospace embedded software. Such embedded software are usually period-driven and can be decomposed into different modes with each mode representing a system state observed from outside. Such software may also involve intensive computing in their modes. Currently, there is lack of domain-specific formal modeling languages for such software in the relevant industry. To address this problem, this article proposes a formal visual modeling approach called SPARDL as a concise and precise way to specify such software. To capture the temporal properties of aerospace embedded software, a property specification language is provided based on interval logic. To support application in industry, code generation methodology is also discussed. This modeling approach is applied in some real-life cases in aerospace industry. |
