In Proceedings of the ASWEC 2015 24th Australasian Software Engineering Conference (Vol. II, pp. 106–110). New York, USA: ACM. http://doi.org/10.1145/2811681.2811702978-1-4503-3796-0https://hdl.handle.net/10289/9795We talk in this paper about using state machines and refinement to characterise the visualisation of a computation. We use Z specifications to give examples of systems in the usual way, and then use Z schemas to also represent states and transitions in state machines, which we consider to be a particular kind of visualisation of a specified system. We have investigated the principle of substitutivity and the idea of downward simulation to check whether or not a refinement relation exists between the specification and the state machine. We are looking at this because we believe that the soundness of the visualisation can be captured by such a refinement relationship.application/pdfen© 2015 Copyright held by the owner/author(s).
