A system-level view of program execution can be helpful in identifying problems during program execution including correctness and performance issues. Problems such as missing or mismatching locks, buffer overruns, and incorrect programming of DMA buffers are examples that are difficult to debug by using explicit print statements or by using traditional interactive debuggers. A systematic way of collecting system level traces for the program execution is needed. The AI Engine architecture has direct support for generation, collection, and streaming of events as trace data during simulation, hardware emulation, or hardware execution.
Note: The event trace feature for hardware execution is an early access feature.
