You can collect profile statistics of your design by calling event APIs in your PS host code. These event APIs are available both during simulation and when you run the design in hardware.

The AI Engine has hardware performance counters and can be configured to count hardware events for measuring performance metrics. You can use the run-time event API together with the graph control API to profile certain performance metrics during a controlled period of graph execution. The event API supports only platform I/O ports (PLIO) to measure performance metrics such as platform I/O port bandwidth, graph throughput, and graph latency.

Important: These APIs can be used in AI Engine simulation, hardware emulation, and hardware flows.
