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.
