About EMPHYSIS
The ITEA3 research project EMPHYSIS (Embedded systems with physical models in the production code software) has been running from September 2017 until February 2021. It has been successfully reviewed and won the ITEA Award of Excellence 2021, honored with a Special Vice-chairman award title for being one of the highest scored ITEA projects to date (15 September 2021).
The major goal of the project was to develop a new standard -- eFMI®: Functional Mock-up Interface for embedded systems -- to exchange physics-based models between modeling and simulation environments with software development environments for electronic control units (ECU), micro controllers or other embedded systems and develop prototype implementations for the whole toolchain from physics-based modeling environments to production code on electronic control units. Enabling advanced control and diagnosis functions based on physics models allows the production code in automotive vehicles to be enhanced and the cost and time for the software development of embedded systems to be reduced.
Research achievements
EMPHYSIS won the ITEA Award of Excellence 2021, honored with a Special Vice-chairman award title for being one of the highest scored ITEA projects to date (15 September 2021).
The major research results of the EMPHYSIS project are:
- eFMI® Standard 1.0.0 Alpha 4 specification.
- 11 industrial use cases and 22 Modelica® example use-cases provided as open source library with ~40 real time simulation configurations.
- 13 tool prototypes supporting eFMI®, including support in established physics modeling and embedded code generation and analysis tools like (third party marks and brands are the property of their respective holders): Simcenter Amesim (Siemens Digital Industries Software), Dymola (Dassault Systèmes), OPTIMICA Compiler Toolkit (Modelon AB), SimulationX (ESI Group), SCODE-CONGRA (ETAS GmbH), AUTOSAR Builder (Dassault Systèmes), TargetLink (dSPACE GmbH), Astrée (AbsInt GmbH), TPT (PikeTec GmbH) and CATIA ESP (Dassult Systèmes).
- Performance assessment with 6 benchmarks on a Bosch MDG1 Electronic Control Unit (ECU): On average, the best performing eFMI® C codes are 25% faster than state of the art hand-written C code.
- 42 journal and conference publications related to eFMI®.
- One major overview paper providing an introduction of the eFMI® technology and summarizing the research results of EMPHYSIS and the eFMI® Standard.
- Public industrial demonstrator report, summarizing the used tooling and tool interactions, the performance assessement conducted to compare eFMI® with state of the art embedded software development, the testsuite and unit tests to validate eFMI® tooling compatibility (crosschecks) and the varying actual industrial demonstrators and their challenges and eFMI®-based solution.
- Public excerpt form the presentations given at the final ITEA3 EMPHYSIS review. The slide set is comprehensive, going into the details of EMPHYSIS research results and the eFMI® Standard, including motivation, developed tooling and performance assessement.
Continuation as Modelica Association Project
The results of the EMPHYSIS project have been transferred to the in 2021 founded Modelica Association Project Functional Mock-up Interface for embedded systems (MAP eFMI®) under the umbrella of the non-profit Modelica Association, to prepare them for open access standardization and publication and the organization of a volunteer community promoting and developing eFMI®. Eleven of the original EMPHYSIS project partners immediately joined MAP eFMI®, demonstrating their strong believe and commitment in the eFMI® technology.
Besides the eFMI® Standard itself, MAP eFMI® releases accompanying promotion material and support tooling like an eFMI Compliance Checker and eFMI Container Manager, all developed as open source projects and distributed on the MAP eFMI® website for free.
