Abstract

In recent years, the focus on embedded real-time systems has largely intensified. More and more products use embedded microcontrollers in order to enhance their functionality and user-interfaces. Unfortunately, analysis tools for real-time systems have not followed the same rapid development. In addition, analysis of real-time systems, like monitoring, debugging and visualization, is made difficult from the temporal and embedded nature of real-time systems. This paper describes a prototype of a real-time debugging system for the Asterix real-time kernel. The system proposed supports deterministic replay, a way of reproducing executions in order to isolate the bugs that cause errors. The executions are replayed in a debugger using a software simulator of the target hardware, making it possible to track down bugs only using a host PC for debuggging.
