Verification of today's Systems-on-Chip (SoC) occur at low abstraction-levels, typically at register-transfer level (RTL). As the complexity of SoC designs grows, it is increasingly important to move verification to higher abstraction-levels. Hardware/software co-simulation is a step in this direction, but is not sufficient due to inaccurate processor models, and slow hardware simulation speeds. System-level monitoring, commonly used for event-based software debugging, provides information about task scheduling events, inter-task communication and synchronisation, semaphores/resources, I/O interrupts, etc. We present MAMon, a monitoring system that can both monitor the logic-level and the system-level in single/multiprocessor SoCs. A small hardware probe-unit is integrated in the SoC design and connects via a parallel-port link to a host-based monitoring tool environment. The probe-unit collects all events in the target system in run-time, and timestamps them with a resolution of 1 µs. The events are then stored in a database on the host for further processing. The paper will describe MAMon and how it works for software and hardware monitoring. The paper also describe how system-level monitoring can be achieved non-instrusively by using a hardware-based Real-Time Kernel.
