Example of appropriate translation Related work The work presented here is complemented by ongoing work at McMaster University by Lawford et al. [6]. Using a similar case study, their work concentrates on veri cation of the re nement of the requirements in the SRS into design elements, also expressed in SCR, in the software design description (SDD) They use an extension of the 4 variable model of Parnas [7] into a relational setting, and ....

....In the following two subsections we describe the variation of the formal setting of [6] considered in the paper and review the PVS clocks theory of [2] 2. 1 Systematic Design Verification This section provides an overview of the (functional) Systematic Design Verification (SDV) procedure used in [12, 6] that is the basis of the real time software verification problem posed in Section 5. The method makes use of a form of Parnas tabular representations of mathematical functions [4, 5] to specify the software s behaviour. Tables provide a mathematically precise notation in a visual format that is ....
.... at times t = 0, K, 2K, The verification of real time properties requires us to consider REQ and SOF as mapping from input dataflows to output dataflows since there is typically no longer a direct relationship between the one step transition functions of the SRS and SDD as was the case in [12, 6]. We will use the fact that it is generally easier to verify two implementations are equivalent by comparing their one step transition functions rather than comparing trajectories generated by an implementation to those specified by more abstract requirements. Thus if a new design SOF opt is ....
