MultiSSE: Full Static Emulation of a Multicore System at the example of AUTOSAR RTOS

The System-State Enumeration (SSE) is an analysis technique for real-time systems that builds a graph of all possible system states. Currently, this analysis is bound to a single execution unit (i.e. processor core). Goal of this thesis is to extend the technique to also support multiple execution units. As a first target, the current specification of AUTOSAR should be used, that allows a partitioned multicore architecture.

ARA is a program to statically analyze an application to get different degrees of information, how the application interacts with the operating system to enable further specialization of the operating system. The extended SSE should be implemented in ARA to proof its working.

The tasks that should be done in this thesis are:

Topics covered by this thesis:
static analysis, synchonization, AUTOSAR, Python, C++, C
