  1. 1. Formal Specification and Verification of Safety-Critical Software

    Författare :Daniel Larsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; fault tolerance; safety-critical; dependability; formal verification; Formal specification;

    Sammanfattning : This thesis is about formal specification and formal verification of software and consists of three different parts. In the first two parts, the formal specification language OCL is treated in two different contexts. The third part describes a technique for analysing the consequences of hardware faults as part of formal software verification. LÄS MER

  2. 2. Formal Verification of Tree Ensembles in Safety-Critical Applications

    Författare :John Törnblom; Simin Nadjm-Tehrani; Ingemar Söderquist; Joao Marques-Silva; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Formal verification; Machine learning; Tree ensembles;

    Sammanfattning : In the presence of data and computational resources, machine learning can be used to synthesize software automatically. For example, machines are now capable of learning complicated pattern recognition tasks and sophisticated decision policies, two key capabilities in autonomous cyber-physical systems. LÄS MER

  3. 3. Towards Formal Verification in a Component-based Reuse Methodology

    Författare :Daniel Karlsson; Petru Eles; Zebo Peng; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Formal verification; Model checking; Petri net; Reuse; Computer science; Datavetenskap;

    Sammanfattning : Embedded systems are becoming increasingly common in our everyday lives. As techonology progresses, these systems become more and more complex. Designers handle this increasing complexity by reusing existing components (Intellectual Property blocks). LÄS MER

  4. 4. Automated Approaches for Formal Verification of Embedded Systems Artifacts

    Författare :Predrag Filipovikj; Cristina Seceleanu; Jim Woodcock; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; Simulink; systems specifications; model-checking; formal verification; Computer Science; datavetenskap;

    Sammanfattning : Modern embedded software is so large and complex that creating the necessary artifacts, including system requirements specifications and design-time models, as well as assuring their correctness have become difficult to manage. One challenge stems from the high number and intricacy of system requirements that combine functional and possibly timing or other types of constraints, which make them hard to analyze. LÄS MER

  5. 5. Automatic Extraction of Program Models for Formal Software Verification

    Författare :Pedro de Carvalho Gomes; Dilian Gurov; Einar Johnsen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Verification; Static Analysis; Program Models; Petri Nets; Compositional Verification; Concurrency; Datalogi; Computer Science;

    Sammanfattning : In this thesis we present a study of the generation of abstract program models from programs in real-world programming languages that are employed in the formal verification of software. The thesis is divided into three parts, which cover distinct types of software systems, programming languages, verification scenarios, program models and properties. LÄS MER
