In this paper we discuss a novel approach to building a model-checker for Z, which involves implementing a translation from Z into SAL, the input language for the Symbolic Analysis Laboratory, a toolset which includes a number of model-checkers and a simulator. The Z2SAL translation deals with a number of important issues, including: mapping unbounded, abstract specifications into bounded, finite models amenable to a BDD-based symbolic checker; converting a non-constructive and piecemeal style of functional specification into a deterministic, automaton-based style of specification; and supporting the rich set-based vocabulary of the Z mathematical toolkit. This paper discusses progress made towards implementing as complete and faithful a translation as possible, while highlighting certain assumptions, respecting certain limitations and making use of available optimisations. The translation is illustrated throughout with examples; and a complete working example is presented, together with performance data.<\/jats:p>","DOI":"10.1007\/s00165-009-0126-7","type":"journal-article","created":{"date-parts":[[2009,10,1]],"date-time":"2009-10-01T16:02:05Z","timestamp":1254412925000},"page":"43-71","source":"Crossref","is-referenced-by-count":11,"title":["Z2SAL: a translation-based model checker for Z"],"prefix":"10.1145","volume":"23","author":[{"given":"John","family":"Derrick","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Sheffield, Regent Court, 211 Portobello, S1 4DP, Sheffield, UK"}]},{"given":"Siobh\u00e1n","family":"North","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Sheffield, Regent Court, 211 Portobello, S1 4DP, Sheffield, UK"}]},{"given":"Anthony J.
