Network-on-Chip (NoC) is generally regarded as the most promising solution for the future on-chip communication scheme in giga-scale integrated circuits. As traditional debug architecture for bus-based systems is not readily applicable to identify bugs in NoC-based systems, in this paper, the authors present a novel debug platform that supports concurrent debug access to the Cores Under Debug (CUDs) and the NoC in a unified architecture. By introducing core-level debug probes in between the CUDs and their network interfaces and a system-level debug agent controlled by an off-chip multi-core debug controller, the proposed debug platform provides in-depth analysis features for NoC-based systems, such as NoC transaction analysis, multi-core cross-triggering and global synchronized time-stamping.
