— This paper briefly describes the ELDATool, a Statecharts-based visual tool for the rapid prototyping of MultiAgent Systems based on the Event-driven Lightweight Distilled Statecharts-based Agents (ELDA) model. In particular, the ELDATool, which is implemented in Java as an Eclipse plug-in, supports an iterative process involving the following phases: detailed design, automatic code generation and simulation. The high-level design, which is the input to this iterative process, can be obtained through currently available agent-oriented methodologies such as PASSI and GAIA. In order to show the main characteristics of the ELDATool, a simple case study is presented.
