Tool-based analytic techniques such as formal verification may be used to justify the quality, correctness and dependability of software involved in digital control systems. This paper reports on the development and application of a tool-based methodology, the purpose of which is the formal verification of freedom from intrinsic software faults related to dynamic memory management. The paper introduces the operational and research context in the power generation industry, in which this work takes place. The theoretical framework and the tool at the cornerstone of the methodology are then presented. The paper also presents the practical aspects of the research: software under analysis, experimental results and lessons learned. The results are seen promising, as the methodology scales accurately in identified conditions of analysis, and has a number of perspectives which are currently under study in ongoing work.
