ESI Group: EMPHYSIS – The Missing Link Between Digital Simulation and Embedded Software

Share

Regulatory News:

ESI Group (Paris:ESI):

The research project EMPHYSIS led by Bosch has delivered the new “eFMI standard” for model exchange to accelerate the model-based development of embedded software. On the 15th of September, this international collaborative project gathering 25 industrial and academic partners from different fields (like automotive and information technologies) situated in Belgium, Canada, France, Germany, and Sweden received the ITEA Award of Excellence for this unique achievement.

Better code with less effort through “eFMI” - the new model-exchange standard for embedded devices

When developing a new function, many engineers learn the hard way that their outstanding knowledge about the physics of their products is not enough by far to develop a function for an embedded target, due to the demanding requirements of safety-critical software, weak CPU magnitude and less memory than expected. While this might result in a never-to-be-realised excellent initial idea of operating and controlling their product in a much smarter way, at the same time it reveals the need for a link between digital simulation of physical processes and embedded software.

The aim of the EMPHYSIS project (Embedded Systems with Physical Models in the Production Code Software), led by Bosch, was to jointly come up with a new open standard that lays the foundation to develop new innovative tools. This that allows model-based functions to be realized directly in embedded software with better code and less effort. For this purpose, the project carried forward the idea of the very successful Functional Mock-up Interface (FMI) model exchange standard for simulation to develop FMI for embedded systems - the new “eFMI standard”. This enables a wide variety of advanced model-based approaches for control and diagnosis, such as solving a set of differential equations to compute a signal instead of measuring it via a sensor. By allowing a hardware sensor to be replaced with a piece of software, we significantly reduce the total cost.

« The EMPHYSIS project has achieved several outstanding results such as the automatic generation of efficient code for embedded devices. It shows the power of collaborative research projects to drive the adoption of a new standard and to generate significant productivity gains for the industry. »

– Jean-François Lavignon, ITEA Vice-chairman

The technical deep dive and benefits

Technically speaking, eFMI is innovative in that it provides a target-independent intermediate format defined by an entirely new language, the Guarded Algorithmic Language for Embedded Control: GALEC. This new programming language is able to guarantee that an algorithm described in this language can be translated into code that has:

  • static worst-case execution time;
  • static a-priori known memory demand; and
  • a statically proven absence of illegal memory access.

In other words: code that satisfies the hard requirements of automotive safety-critical embedded software, which also makes it applicable to many more, less restricted domains like robotics, industrial applications and consumer goods.

With eFMI and GALEC it is now possible to capture the computational essence of a model in a target-independent form that is a solid foundation for any code generator to produce highly optimised code for arbitrary runtime environments and software architectures. All this is cast into a traceable, extendable and verifiable container architecture that goes far beyond a simple exchange format.

The eFMI workflow allows developers to model a system on a higher level of abstraction, starting with a reusable, high-level, component-oriented and physically structured model. The tooling kit then automatically transforms this into a solution which can be better integrated into software.

The main benefits of this solution and the associated eFMI workflow are:

  • accelerating development time;
  • better use of domain experts by separating the concerns of physical modelling and embedded implementation;
  • overcoming vendor lock-in through eFMI being published as an open standard on GitHub; and
  • enabling new ways of OEM supplier collaborations.

Continuous success

An OEM Advisory Board has been established to gather additional requirements, input and use-cases and further disseminate the project’s results, helping to secure uptake and future innovations in new domains.

On 22 March 2021, right after the project’s end, the non-profit Modelica Association officially approved a new project under its umbrella to further develop, standardize and promote eFMI. With Robert Bosch GmbH, Dassault Systèmes, DLR Institute of System Dynamics and Control, dSPACE, ESI Group, ETAS GmbH and Modelon AB as initial members of the steering committee and Mercedes-Benz AG having joined recently, the first official release of eFMI 1.0 is targeted within 2021. Having developed 14 tools within EMPHYSIS, eFMI already has a broad foundation even before its official release.

« What makes us proud as a team is the fact that this success has been recognized not only by our business partners and the OEM Advisory Board representing the voice of the customer, but also by the ITEA organization.»

– Oliver Lenord, Research Engineer at the Model-based Systems Engineering department at Robert Bosch

For society as a whole, EMPHYSIS’ better software translates into safer and more efficient vehicles which are able to keep pace with customer demands and help tackle climate issues in the longer term. For the time being, however, the project’s message is clear: by taking full advantage of an equation-based, component-oriented modelling language with a good library, 90% gains can be made in productivity of model-based function development.

Disruptive.Asia: Huawei's Ryan Ding and Peng Song Discuss How Operators Can Leverage Connectivity to Unlock New Growth22.10.2021 13:30:00 EEST | Press release

Disruptive.Asia reported that Ryan Ding and Peng Song stressed the growing importance of connectivity in driving industry growth and generating value amid a rapidly evolving landscape at the 7th Ultra-Broadband Forum (UBBF 2021) in Dubai, which is jointly hosted by the UN Broadband Commission and Huawei. Ding, Executive Director of the Board and President of the Carrier Business Group, Huawei, said that connectivity has made it possible to innovate, especially in a digital age where increasing efficiency has become paramount. The pandemic has also ushered a paradigm shift in connectivity, as homes turned into multi-functional centers for education, work, and business. It became increasingly clear that connectivity not only drives digital economies forward but also maintains the functioning of society. Peng, President of the Global Carrier Marketing & Solution Sales Department, Huawei, said that looking at connectivity through Huawei's C.A.F (Coverage, Architecture and Fusion) model can

Suzano Brings Its Target for Capturing 40 Million Tons of Carbon From the Atmosphere Forward To 202522.10.2021 13:19:00 EEST | Press release

Suzano, the world's leading eucalyptus pulp producer and a global benchmark in the manufacture of bioproducts developed from eucalyptus, announces today that it has revised one of its 14 long-term goals – collectively known as Suzano’s “Commitments to Renewing Life”*. Suzano’s goal to remove 40 million tons of carbon from the air by 2030 has been brought forward by five years to 2025. With this revision, Suzano reinforces its capacity to make an even more positive contribution to the planet's climate by achieving net carbon removals from the atmosphere at a faster pace than previously expected. The new five-year target will be supported by the expansion of Suzano’s forest covering which will involve both an uplift in commercial planting operations and setting aside new designated conservation areas that were previously anthropized. Alongside these improvements, Suzano will maintain its focus on reducing carbon emissions across its own operations and supply chain and will continue to im
