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. This thesis focuses on formal verification of automatically generated C code based on Simulink models using deductive verification techniques. More specifically, the aim is to ex- plore whether the generated code can be automatically annotated using the underlying Simulink model as an executable specification, thereby making it suitable for verification using state-of-the-art tools. Our in- vestigation of Simulink generated C code shows that the same can be annotated using the corresponding Simulink model as an executable specification. Consequently, we propose an algorithm that automates the annotation generation and their injection into C code for a specific class of Simulink models and code generated under specific conditions. Successful verification would mean that the code satisfies all functional properties of the model irrespective of the code generator used. We validate our approach on a prototype implementation of a Brake-by-Wire (BBW) functionality of heavy load vehicles. Most of the functional properties of the generated code were satisfied. iv Sammanfattning Det har skett en våg av omvandling inom fordonsindustrin i de senas- te åren, där de flesta fordonsfunktioner nu styrs elektroniskt istället för mekaniskt. Detta har lett till en exponentiell ökning i komplexite- ten av programvarufunktioner i fordon, vilket gör det väsentligt för tillverkare att kunna garantera deras korrekthet. Traditionell testning av programvara är nära sina gränser och driver därför bilindustrin att utforska andra former av kvalitetssäkring. En teknik som har fått fart genom åren är en uppsättning verifieringstekniker baserade på matematisk logik som kallas formella verifikationstekniker. Även om formella tekniker ännu inte har införts på en stor skala erbjuder dessa metoder systematisk och möjligen mer genomgripande verifiering av programvaran som testas, eftersom dess grund är baserad på mate- matikens principer. För att kunna tillämpa formell verifiering behöver systemet som testas omvandlas till en formell modell och en upp- sättning egenskaper över sådana modeller, som sedan kan verifieras med hjälp av några väletablerade formella verifieringstekniker, såsom modellkontroll eller deduktiv verifiering. Denna avhandling fokuse- rar på formell verifiering av automatiskt genererad C-kod baserad på Simulink-modeller med hjälp av deduktiva verifieringstekniker. Mer specifikt är syftet att undersöka om den genererade koden automa- tiskt kan antecknas med den underliggande Simulink-modellen som en körbar specifikation, vilket då skulle göra den lämplig för verifiering med toppmoderna verktyg. Vår undersökning av Simulink-genererad C-kod visar att samma sak kan kommenteras när den motsvarande Simulink-modellen används som en körbar specifikation. Följaktligen föreslår vi en algoritm som automatiserar anteckningsgenereringen och dess injektion i C-kod för en specifik klass av Simulink-modeller och kod genererad under specifika förhållanden. Lyckad verifiering skulle betyda att koden uppfyller alla funktionella egenskaper av mo- dellen oavsett vilken kodgenerator som används. Vi validerar vår strategi med en prototypimplementering av en Brake-by-Wire (BBW) -funktionalitet för tunga lastbilar. De mesta funk- tionella egenskaperna för den genererade koden var uppfyllda. v Acknowledgements This thesis is the culmination of seven months of relentless effort and several sleepless nights.

This has resulted in leading vehicle manufacturers spending a significant portion of time in developing real-time safety critical code as well as assuring its cor- rectness. For complex and safety-critical functions, it becomes ever challenging to guarantee their correctness at all times using traditional verification techniques such as software testing and peer-reviews. Con- sequently, this has helped propel formal techniques to the forefront. Formal methods use the underlying principles of mathematics to prove properties of the system under test, thus making it a more reliable and accurate mode of verification. Being a manufacturer of trucks and buses recognized on a global scale, Scania is actively involved in verifying the functional correctness of their developed code and also ensuring that it adheres to safety stan- dards such as the ISO 26262 [1], which recommends formal verification of all safety critical code. Recent years have seen the rise of model based forms of software de- velopment [2], where code is generated automatically with the help of advanced tools (such as Embedded Coder [3]) as compared to develop- 1 2 CHAPTER 1. INTRODUCTION ers writing code from scratch. These tools or autocoders are assumed to generate code that functionally satisfies all properties of the model. Being at the threshold of transformative changes in the automotive industry, it has never been more important for vehicle manufacturers to be able to guarantee safety on roads. This serves as the key motivation for this thesis which focuses on ensuring the functional correctness of the code with respect to its input modelling language. Our research is centred around verifying that the generated code implements and only implements properties of the input Simulink model. In order to do so, certain changes or annotations (section 2.5) need to be introduced into the generated code. Our initial assumption is that the input-output mapping function of each block from the stan- dard Simulink library can be represented by a unique contract spec- ification (section 2.4.2). The contracts are written as annotations and injected into appropriate control points in the generated code. The annotated code can then be verified using state-of-the-art formal verifi- cation tools. Successful verification means that the contracts extracted from the model are fulfilled by the generated code as well.

  • 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.

(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.
