TY - THES A1 - Tchuemkam Tadjuidje, Hermann T1 - Simulation of the temporal behavior of logical execution time in combination with classical tasks in an AUTOSAR Classic multi-core computer system using the tool ChronSim. N2 - Modern automotive systems have transitioned to distributed architectures, necessitating their embedded real-time software to be deterministic to ensure that they operate properly. To achieve this deterministic behavior, the Bounded Execution Time (BET) model, in combination with the Logical Execution Time (LET) paradigm, is applied on some software. This scheduling method is tested for applicability on new software projects at the early-concept phase of their development. This research is done by performing scheduling simulation with the tool chronSIM by INCHRON. However, chronSIM lacks basic model object to represent LET tasks. This thesis addresses this deficiency by presenting a model for LET within an AUTOSAR classic multi-core computer system, all within the chronSIM tool. The research elaborates on creating a model for LET tasks using the basic model objects available in chronSIM. Furthermore, an existing scripted modeling toolchain, used by Vitesco Technologies engineers for software project modeling and simulation, is upgraded to model LET tasks and introduces new configuration options which can be used to setup a couple LET scheduling scenarios. The thesis also includes simulation of several projects, with in-depth analysis of their simulation results. The primary objective of this thesis is to advance the simulation process of automotive software to analyze the applicability of a range of scheduling configurations.
