Tool Overview and Functionality
📌 The speaker introduces a plug-in tool built on top of Eclipse for easily developing state charts (available at www.hs).
🔧 The tool supports model editing, creation, validation (checking syntactic correctness), and execution/simulation of the models.
⚙️ A key feature is the code generation capability, supporting languages like Java, C, and C++.

Creating a Simple Clock State Chart
🖥️ A new Eclipse project is created, and the user switches to the Kindle modeling perspective for a visual interface.
⚙️ The initial state chart is created, starting with a default, unnamed initial state.
➡️ Two states are defined: "display hour" and "display seconds," with an initial transition error flagged because the second state was unreachable.
🔗 A transition is added between the two states, triggered by an event named "mode," creating a cyclic behavior between the states.

Simulating the State Chart Model
🖱️ The model simulation is initiated by clicking the Run button, requiring the model file to be saved first.
👁️ The simulation view on the right displays the available events in the default interface, including the mode event.
🔄 Clicking the "mode" event manually triggers the transition from "display hour" to "display seconds," and clicking it again fires the reverse transition, demonstrating the cyclic loop.

Key Points & Insights
➡️ The tool significantly simplifies the creation and manipulation of state charts through a dedicated visual environment.
➡️ Syntactic validation occurs in real-time, indicated by error signs (like a red cross) when states are unreachable or transitions are incomplete.
➡️ The ability to manually trigger defined events during simulation allows for immediate verification of state machine logic flow.
