Abstract
针对嵌入式实时软件需求规约及其检测问题,提出了基于层次并发有穷状态机的可合成的图形化建模语言RTRSM*(real-time requirements specification model*),利用转换有效期和事件预定机制来描述时间限制,能够较好地支持系统交互性和实时性的建模.为弥补RTRSM*作为操作性规约语言不便于性质描述的问题,提出了命题时序逻辑RITL(real-time interval temporal logic).该语言以时间状态序列为语义模型,具有基于区间和时间点的量化时间属性描述功能,能自然、全面地描述RTRSM*模型性质.介绍并讨论了基于两种语言的规约检测方法和技术,主要包括系统状态空间有穷的RTRSM*模型状态可达图的相关问题和规约的模拟执行
