Description

In order to improve the quality of embedded software, this paper proposes Information Flow Diagram and a requirements analysis method by applying the diagram for finding unexpected obstacles, in the software, which are difficult to be assumed in software specification. Recently, embedded systems have become large in scale and complicated. Therefore, the development cycle of the systems is desirable to be lengthened. However, the cycle is required to be shortened on the contrarey. This trend of industry troubles the quality of embedded software. In order to improve the quality of the software, unexpected obstacles should be carefully analyzed in its specification and design processes. Therefore, we propose the analysis method and describe a case study. Moreover, we outline a description experiment of Information Flow Diagram, by using an actual product, which proved that novice engineers can make Information Flow Diagram under the lead of embedded software expert engineers.
