In-Band Cross-Trigger Event Transmission for Transaction-Based Debug

Cross-trigger, the mechanism to trigger activities in one debug entity from debug events happened in another debug entity, is a very useful technique for debugging applications involving multiple embedded cores. Existing solutions rely on dedicated interconnects (i.e., different from functional interconnects) to transfer debug events and cannot guarantee the arrival time of the debug events coincides with the arrival time of the data messages between multiple cores. This results in mismatches between the observed system internal operations and the ones that designers expect to watch.
