Abstract

OSEK/VDX has proposed a standard for operating systems used in automotive systems. This standard is described in the form of informal specification. The informal specification is not suitable for applying formal methods to the whole of the software development because the ambiguity of the specification causes many problems in the development. Hence, we are formalizing the specification of OSEK/VDX using a formal specification language. Because this specification has been standardized, we do not change it but faithfully formalize it. This paper shows our approach to faithfully formalize this specification. On the one hand, it aims at bi-directional traceability between the informal specification and the formal specification. On the other hand, it aims at feasibility of checking the meaning of the formal definition with the meaning of the informal description. Therefore, this approach supports validating the formal specification against the informal specification. Consequently, it improves the confidence of the equivalence between the informal specification and the formal specification.

忠实地形式化OSEK/VDX操作系统规范

OSEK/VDX提出了用于汽车系统的操作系统标准。本标准以非正式规范的形式进行描述。非正式规范不适合将正式方法应用于整个软件开发，因为规范的模糊性会导致开发中的许多问题。因此，我们正在使用一种形式化规范语言形式化OSEK/VDX规范。因为这个规范已经标准化了，所以我们不会改变它，而是忠实地将它形式化。本文展示了我们忠实地形式化该规范的方法。一方面，它旨在实现非正式规范和正式规范之间的双向可追溯性。另一方面，探讨用非正式描述的意义来检验正式定义意义的可行性。因此，这种方法支持根据非正式规范验证正式规范。因此，它提高了非正式规范和正式规范之间等价的置信度。
