Development of a Generic Voter under FoCaL

摘要

Safety and security are claimed major concerns by the formal FoCaL development environment. In [7] we introduced a safety development cycle customised to FoCaL. In this paper, we examine how to specify and implement a concrete example following this cycle. We show that indeed it is feasible and we present how FoCaL features fit with software best practises like modularity, reuse, fault confinement and maintenance.
