Simulink Legacy Tool

This tool analyzes legacy Simulink models to determine compatibility with newer MATLAB release targets and hardware platforms, enabling migration planning without running simulations. It ingests model files (.slx/.mdl) or project references, extracts block usage, data paths, and dependencies, and applies a rule-based matrix to flag deprecated blocks, incompatible configurations, and moved or renamed APIs. Outputs include remediation suggestions and sequencing guidance. The analysis generates a structured report with a compatibility score, risk factors, estimated effort, and a staged migration plan. Core checks are always performed; advanced capabilities support domain-specific extensions, custom rule sets, and batch analyses to scale across portfolios. Use cases span automotive control systems migrating to current toolchains, avionics models requiring updated safety features, and industrial automation projects seeking longer lifecycle support. The tool provides a planning framework, cost estimates, and measurable milestones that align engineering work with management timelines. Unique value includes explicit legacy-to-modern assessment, both block- and path-level analyses, and exportable migration plans compatible with downstream workflows, version control, and CI pipelines. It emphasizes early risk visibility, target-version readiness, and traceable decisions. Limitations include not executing or validating simulations, not generating production code, and relying on accessible model artifacts. Results are planning guidance intended to inform validation strategies and resource allocation. Users should supplement the tool outputs with formal testing to ensure functional equivalence post-migration.
