Abstract
The rapid design of the embedded system is crucial for improving the product’s competitiveness. Existing statechart tools used for designing the embedded system rely on the copy and paste of the statechart for reuse. However, such method has a major drawback of wasting both time and cost of the system developer. This paper implements the component supporting tool. A tool that makes efficient reuse of a statechart by adding a component function to the existing functions is implemented in this paper. Also, to add a component function, this paper restructured the contract as protocol of the inter-component. The implemented tool helps not only reduce the life cycle of a product, but also enhance a product’s competitiveness by supporting the product’s time-to-market.
