emmtrix Performance Estimator

emmtrix Performance Estimator provides Simulink developers with early, reliable, and fully reproducible insight into the runtime behavior of their generated code on embedded hardware. By evaluating the C code that Simulink models produce and combining it with an abstract hardware description, the tool predicts execution times at block, module, and model levels without requiring target hardware, runtime measurements, or manual preparation. Results are deterministic, making performance analyses repeatable and comparable throughout the project lifecycle.

The tool supports workflows by running on a standard development PC or as part of a continuous integration (CI) pipeline, enabling continuous monitoring of performance characteristics across all code changes. The tool's automated analysis framework ensures that timing evaluations are consistent and integrated into existing development processes.

To support informed engineering decisions, the estimator can provide minimum, maximum, and average execution times, offering a clear view of expected runtime ranges. Further refinement of these estimates is possible with user-provided data, such as measured runtimes, known constraints, or bounds on loop iterations. The approach introduces no measurement overhead, even for small code fragments, and can incorporate compiler optimizations to better reflect real-world execution behavior.

emmtrix Performance Estimator is beneficial for anyone using Simulink who needs dependable runtime information for embedded targets to validate timing budgets, identify bottlenecks, guide architectural choices, and ensure that performance constraints are met early in the development process.
