Abstract
The RT-Middleware is a software platform for RT-System development. In RT-System development based on the RT-Middleware, the system consists of RT-Components that are modularized RT functional elements. The system development life-cycle often can be iterative process across the whole development phase. In such development process, integrated development environment (IDE) can be an effective tool for system developers. In this paper, we propose the basic RT-Systems development life-cycle and the integrated development environment that consists of a lot of helper tools to realize concurrent development process for RT-systems.
