Requirements for a Trace Property Language for Medical Devices

Abstract

The verification of software intensive medical devices can largely benefit from the analysis of their execution traces. Trace points can easily be added to the software, and traces can be used at several stages of the development and maintenance process. In this paper we focus on the TKA system and identify 15 representative properties that should be fulfilled by its traces. We also identify several stages in the product lifecycle where these properties should be evaluated. These properties put requirements on what should be expressible in a trace property language for medical devices.
