    • Asynchronous vs. Synchronous Interfacing to Time-Triggered Communication Systems 

      Puschner, Peter; Kirner, Raimund (2020-02-01)
      Time-triggered communication facilitates the construction of multi-component real-time systems whose components are in control of their temporal behaviour. However, the interface of a time-triggered communication system ...

    • Automated formal verification and testing of C programs for embedded systems 

      Kandl, Susanne; Kirner, Raimund; Puschner, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2007)
      In this paper, we introduce an approach for automated verification and testing of ANSI C programs for embedded systems. We automatically extract an automaton model from the C code of the SUT (system under test). This ...

    • Cross-platform verification framework for embedded systems 

      Wenzel, Ingomar; Kirner, Raimund; Rieder, Bernhard; Puschner, Peter (Springer Nature, 2007-09)
      Many innovations in the automotive sector involve complex electronics and embedded software systems. Testing techniques are one of the key methodologies for detecting faults in such embedded systems.In this paper, a novel ...

    • Error Detection Rate of MC/DC for a Case Study from the Automotive Domain 

      Kandl, Susanne; Kirner, Raimund (Springer Nature, 2010)
      Chilenski and Miller [1] claim that the error detection probability of a test set with full modified condition/decision coverage (MC/DC) on the system under test converges to 100% for an increasing number of test cases, ...

    • From time-triggered to time-deterministic real-time systems 

      Puschner, Peter; Kirner, Raimund (Springer Nature, 2006)
      With the increased use of powerful, performance-optimized hardware components in embedded systems, timing prediction is getting more and more complex. Thus while the execution speed of software is generally increasing, it ...

    • Interfacing to Time-Triggered Communication Systems 

      Puschner, Peter; Kirner, Raimund (2019-07-11)
      Time-triggered communication facilitates the construction of multi-component real-time systems whose components are in control of their temporal behavior. However, the interface of a time-triggered communication system has ...

    • Measurement-Based Timing Analysis 

      Wenzel, Ingomar; Kirner, Raimund; Rieder, Bernhard; Puschner, Peter (Springer Nature, 2009)
      In this paper we present a measurement-based worst-case execution time (WCET) analysis method. Exhaustive end-to-end execution-time measurements are computationally intractable in most cases. Therefore, we propose to measure ...

    • Model-driven design and organic computing - combinable strategies? 

      Puschner, Peter; Kirner, Raimund (IEEE COMPUTER SOC, 2009)
      This position paper discusses the possibility to combine organic computing and model-driven design.

    • Obstacles in worst-case execution time analysis 

      Kirner, Raimund; Puschner, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2008)
      The analysis of the worst-case execution time (WCET) requires detailed knowledge of the program behavior. In practice it is still not possible to obtain all needed information automatically. In this paper we present the ...

    • Portable data exchange for remote-testing frameworks 

      Kirner, Raimund; Puschner, Peter; Wenzel, Ingomar; Rieder, Bernhard (IEEE COMPUTER SOC, 2006)
      To communicate between heterogeneous computer systems, mechanisms for data conversion are necessary. In this paper we present a portable, asymmetric data conversion method that is suitable for remote testing frameworks in ...

    • Precise worst-case execution time analysis for processors with timing anomalies 

      Kirner, Raimund; Kadlec, Albrecht; Puschner, Peter (Institute of Electrical and Electronics Engineers (IEEE), 2009)
      This paper explores timing anomalies in WCET analysis.Timing anomalies add to the complexity of WCET analysis and make it hard to apply divide-and-conquer strategies to simplify the WCET assessment. So far, timing anomalies ...

    • A qualitative cybersecurity analysis of time-triggered communication networks in automotive systems 

      Kirner, Raimund; Puschner, Peter (2023-02-08)
      Security is gaining increasing importance in automotive systems, driven by technical innovations. For example, automotive vehicles become more open systems, allowing the communication with other traffic participants and ...

    • A Quantitative Analysis of Interfaces to Time-Triggered Communication Buses 

      Kirner, Raimund; Puschner, Peter (2021-04-28)
      Nodes connected to a time-triggered (TT) network can access the network interface in two different ways, synchronously or asynchronously, which greatly impacts communication timing and message lifespans (i.e., the time ...

    • A Single-Path Chip-Multiprocessor System 

      Schoeberl, Martin; Puschner, Peter; Kirner, Raimund (Springer Nature, 2009)
