A systematic code verification approach for the properties of real-time software model

Abstract

Following the Model-Driven Development method (MDD), real-time software can be developed by building timed-automata model, verifying the model, and generating a code from the verified model systematically. In order to make safety assured real-time software, it is necessary to guarantee that the properties satisfied in the timed-automata model are preserved in the code. We suggest a systematic code verification approach where the code is assumed to be generated from the verified model systematically. We demonstrate the effectiveness of the proposed approach by conducting a case study of the VVI mode and the DDI mode of the pacemaker. Also, we seeded faults into program to see that the approach can find the faults and analyzed the verification results.
