Software Tracing

Event tracing automatically instruments the stub function to capture software control events associated with the implementation of a hardware function call. The event types include the following.

• Accelerator set up and initiation
• Data transfer setup
• Hardware/software synchronization barriers (“wait for event”)

Each of these events is independently traced, and results in a single AXI-Lite write into the programmable logic, where it receives a timestamp from the same global timer as hardware events.
