SAGE: Simulation via Agent-based Generative Engine

SAGE is a multi-agent pipeline that generates Simulink simulation code from input diagrams.
It leverages large language models, multimodal perception, and modular agentic workflows.

🧠 Concept

Given a Simulink-style simulation diagram as input (image format), SAGE produces the corresponding MATLAB Simulink code and runs the simulation automatically.

System Overview

The system includes the following components:

• Multimodal Investigator: Detects blocks and connections from a simulation diagram.
• Unit Test Reviewer: Validates logical correctness of the extracted connections.
• Block Builder: Builds the simulation using matlab.engine in Python.
• Debug Locator: Identifies whether errors come from code logic or overlooked connection issues.
