Computer aided design tools (CAD tools) are necessary for current design processes. A user of these tools needs to program execution order of multiple CAD tools and to execute the programmed tools effectively. This paper proposes a macordataflow model that enables both efficient programming among multiple CAD tools and efficient execution of the tools. The proposed model provides a user visual-programming environment to program execution order of multiple CAD tools, or tasks, and executes the tasks effectively by calculating an earliest executable condition of each task automatically. In addition, the model enables selective task re-execution, in which selected tasks are re-executed in efficient manner, and helps a user to design systems through try and error. The authors developed the prototype of programming environment based on the proposed model. A user of the environment is able to draw a visual program that shows dependence among CAD tools, which are implemented as external software, and the environment invokes execution of the tools in effective order. The prototype showed that the proposed model enables proper and efficient programming among CAD tools, and that the programming environment is able to be an effective programming tool for system designers.
