Reusing Static Analysis Across Di Erent Domain-Specific Languages
Reusing Static Analysis across Dierent Domain-Specific Languages using Reference Attribute Grammars Johannes Meya, Thomas Kühnb, René Schönea, and Uwe Aßmanna a Technische Universität Dresden, Germany b Karlsruhe Institute of Technology, Germany Abstract Context: Domain-specific languages (DSLs) enable domain experts to specify tasks and problems themselves, while enabling static analysis to elucidate issues in the modelled domain early. Although language work- benches have simplified the design of DSLs and extensions to general purpose languages, static analyses must still be implemented manually. Inquiry: Moreover, static analyses, e.g., complexity metrics, dependency analysis, and declaration-use analy- sis, are usually domain-dependent and cannot be easily reused. Therefore, transferring existing static analyses to another DSL incurs a huge implementation overhead. However, this overhead is not always intrinsically necessary: in many cases, while the concepts of the DSL on which a static analysis is performed are domain- specific, the underlying algorithm employed in the analysis is actually domain-independent and thus can be reused in principle, depending on how it is specified. While current approaches either implement static anal- yses internally or with an external Visitor, the implementation is tied to the language’s grammar and cannot be reused easily. Thus far, a commonly used approach that achieves reusable static analysis relies on the trans- formation into an intermediate representation upon which the analysis is performed. This, however, entails a considerable additional implementation effort. Approach: To remedy this, it has been proposed to map the necessary domain-specific concepts to the algo- rithm’s domain-independent data structures, yet without a practical implementation and the demonstration of reuse.

Automated Annotation of Simulink Generated C Code Based on the Simulink Model
DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2020 Automated Annotation of Simulink Generated C Code Based on the Simulink Model SREEYA BASU ROY KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Automated Annotation of Simulink Generated C Code Based on the Simulink Model SREEYA BASU ROY Master in Embedded Systems Date: September 25, 2020 Supervisor: Predrag Filipovikj Examiner: Matthias Becker School of Electrical Engineering and Computer Science Host company: Scania CV AB Swedish title: Automatisk Kommentar av Simulink Genererad C kod Baserad på Simulink Modellen iii Abstract There has been a wave of transformation in the automotive industry in recent years, with most vehicular functions being controlled electron- ically instead of mechanically. This has led to an exponential increase in the complexity of software functions in vehicles, making it essential for manufactures to guarantee their correctness. Traditional software testing is reaching its limits, consequently pushing the automotive in- dustry to explore other forms of quality assurance. One such technique that has been gaining momentum over the years is a set of verification techniques based on mathematical logic called formal verification tech- niques. Although formal techniques have not yet been adopted on a large scale, these methods offer systematic and possibly more exhaus- tive verification of the software under test, since their fundamentals are based on the principles of mathematics. In order to be able to apply formal verification, the system under test must be transformed into a formal model, and a set of proper- ties over such models, which can then be verified using some of the well-established formal verification techniques, such as model check- ing or deductive verification.

FMI Target for Simulink Coder, It Is Now Possible to Export Models from Simulink to Any Platform That Supports Fmus for Co-Simulation
Supporting your vision Cross-Platform Modeling with FMI Target for Simulink® Coder™ Open technology standards for an integrated product lifecycle Engine Transmission Thermal EV/HV Chassis Compo- Models Models Systems Models nents Models Functional Mock-Up Interface The challenge for manufacturers of complex machinery that heavily rely on components from suppliers is the seamless exchange of data and specifications during the development. The same holds true for large corporates with multiple R&D departments at various locations using several development tools due to different objectives. Those challenges include different programming languages from the various tools, the lack of standardized model interfaces and the concerns for the protection of intellectual property. The development of the Functional Mock-up Interface (FMI) has enabled software-, model- and hardware-in-the-loop simulations with dynamic system models from different software environments. With the FMI Target for Simulink Coder, it is now possible to export models from Simulink to any platform that supports FMUs for Co-Simulation. FMI for Co-Simulation The goal is to couple two or more models with solvers in a co-simulation environment. The data exchange between subsystems is restricted to discrete communication points. The subsystems are processed independently from each other by their individual solvers during the time interval between two communication points. Master algorithms control the synchronization of all slave simulation solvers and the data exchange between the subsystems. The interface allows for both standard and advanced master algorithms, such as variable communication step sizes, signal extrapolation of higher order and error checking. FMI Target for Simulink® Coder™ FMI for Co-Simulation For the exchange of models across different platforms, the FMI Target for Simulink Coder enables the export of models from Simulink as FMUs for Co-Simulation.

Making Simulink Models Robust with Respect to Change Making Simulink Models Robust with Respect to Change By Monika Jaskolka, B.Co.Sc., M.A.Sc. a thesis submitted to the Department of Computing and Software and the School of Graduate Studies of McMaster University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Doctor of Philosophy (December 2020) McMaster University (Software Engineering) Hamilton, ON, Canada Title: Making Simulink Models Robust with Respect to Change Author: Monika Jaskolka B.Co.Sc. (Laurentian University) M.A.Sc. (McMaster University) Supervisors: Dr. Mark Lawford, Dr. Alan Wassyng Number of Pages: xi, 206 ii For my husband, Jason iii Abstract Model-Based Development (MBD) is an approach that uses software models to describe the behaviour of embedded software and cyber-physical systems. MBD has become an increasingly prevalent paradigm, with Simulink by MathWorks being the most widely used MBD platform for control software. Unlike textual programming languages, visual languages for MBD such as Simulink use block diagrams as their syntax. Thus, some software engineering principles created for textual languages are not easily adapted to this graphical notation or have not yet been supported. A software engineering principle that is not readily supported in Simulink is the modularization of systems using information hiding. As with all software artifacts, Simulink models must be constantly maintained and are subject to evolution over their lifetime. This principle hides likely changes, thus enabling the design to be robust with respect to future changes. In this thesis, we perform repository mining on an industry change management system of Simulink models to understand how they are likely to change.

TPT Tutorial
Time Partition Testing Systematic automated testing of embedded systems PikeTec GmbH, http://www.piketec.com There are only a few tools for testing embedded systems in the automotive domain. Their function usually lies in the test-management or automation of tests by means of test scripts. Time Partition Testing (TPT) noticeably exceeds this. It combines a systematic and very graphic modelling technique for test cases with a fully automatic test execution in different environments and automatic test evaluation in a unique way. In doing so, TPT even supports testing of control systems. Time Partition Testing (TPT) was developed to graphically and compactly model tests of embedded systems – especially those with continuous behaviour –, to automate those tests and to offer a systematic that supports the tester in selecting an ideal amount of test cases. The intuitive graphic modelling technique for test cases, the mechanisms for the structuring of complex test problems, the simple integration in any test- bench and a number of additional interesting features makes TPT a unique test solution. All this has contributed to TPT becoming the central testing tool in a large number of development projects at car manufacturers and suppliers and has become an integral part of the process chain. Embedded systems TPT is specialized on testing embedded systems whose inputs and outputs can be represented as signals. Most control systems belong to this system class. The implementation language of the embedded system (e.g. ‘C’ code, C++, MATLAB/Simulink/Stateflow, Statemate or a combination of multiple languages) is irrelevant for TPT. TPT does not require a particular implementation language.

Modelica: Equation-Based, Object-Oriented Modelling of Physical Systems
Chapter 3 Modelica: Equation-Based, Object-Oriented Modelling of Physical Systems Peter Fritzson Abstract The field of equation-based object-oriented modelling languages and tools continues its success and expanding usage all over the world primarily in engineering and natural sciences but also in some cases social science and economics. The main properties of such languages, of which Modelica is a prime example, are: acausal modelling with equations, multi-domain modelling capability covering several application domains, object-orientation supporting reuse of components and evolution of models, and architectural features facilitating modelling of system architectures including creation and connection of components. This enables ease of use, visual design of models with combination of lego-like predefined model building blocks, ability to define model libraries with reusable components enables. This chapter gives an introduction and overview of Modelica as the prime example of an equation-based object-oriented language. Learning Objectives After reading this chapter, we expect you to be able to: • Create Modelica models that represent the dynamic behaviour of physical components at a lumped parameter abstraction level • Employ Object-Oriented constructs (such as class specialisation, nesting and packaging) known from software languages for the reuse and management of complexity • Assemble complex physical models employing the component and connector abstractions • Understand how models are translated into differential algebraic equations for execution 3.1 Introduction Modelica is primarily a modelling language that allows specification of mathematical models of complex natural or man-made systems, e.g., for the purpose of computer simulation of dynamic systems where behaviour evolves as a function of time.
