Combined hardware and software tracing of real and virtual embedded system parts

Advanced debug support and trace capabilities are getting ever more important for overcoming the challenges of developing complex real-time embedded systems containing complex Systems-on-Chip (SoCs). Gathering and handling of very large software and system traces becomes a major challenge. We present an approach of recording and fusing software and system traces in combined simulated and real system development environment. This provides a complete, time aligned view of the whole system behavior. The development environment is based on the Chip-Hardware-In-The-Loop Simulation (CHILS) approach [1], which embeds a real microcontroller (MC) into different simulation environments.
