1.3 On-Chip Debug Support (OCDS)

The Infineon AURIX™ TC3XX devices contain powerful resources for debugging and performance optimization. They provide high visibility and controllability of software, hardware and system, especially under hard real-time constraints. The resources are either embedded in specific modules (e.g. breakpoint logic of CPUs) or part of the central Cerberus module.

Trace functionality is available for TC3XX with miniMCDS, MCDSlight or MCDS. Please refer to the table “Platform Feature Overview” for more details.

When acting as a bus master, Cerberus shares the master interfaces of the DMA (using a different master tag) to access memories and SFRs attached to the SPB or SRI via the shortest possible path.
