摘要
本文介绍了利用高阶逻辑(HOL)证明系统开发深空网络微波通用控制器(UGC)软件的实验。这些实验探索了UGC软件的Swi-Int(开关联锁)主题的各种形式的需求,这些需求在Peters嵌入在HOL中的类似csp的实时过程代数中正式指定(参见IEEE Wescon/94, Anaheim, CA, September 27-29, 1994)。Swi-Int管理器的行为在知识图中以图形方式指定,并以HOL编写的过程代数公式的形式指定。为了避免管理器行为的动态锁定,在管理器的设计中引入了时间约束。因此,在Peters中,Swi-Int的并行行为被细化,以包含经理行为的细化。
Experiments using higher order logic in developing DSN controller software
This paper presents experiments using the higher order logic (HOL) proof system in developing microwave generic controller (UGC) software for the Deep Space Network. These experiments explore various forms of requirements for the Swi-Int (switch interlock) subject of the UGC software formally specified in a CSP-like real-time process algebra embedded in HOL by Peters (see IEEE Wescon/94, Anaheim, CA, September 27-29, 1994). The behavior of the Swi-Int manager is specified graphically in a knowledge graph and as a process algebra formula written in HOL. In an effort to avoid the possibility of livelock in the behavior of the manager, timing constraints are introduced into the design of the manager. As a result, the parallel behavior of the Swi-Int in Peters is refined to incorporate the refinement of the behavior of the manager.<>
