You can cross-probe from a specific input or output window net connection in the graph view to its equivalent position in the Event Trace view. You can trace window input data as it buffers prior to the kernel starting execution. Use the following steps to perform data analysis on a window interface.
  1. The following figure shows a net connection selected in the Graph view. Selecting a net (for example, net0 ) highlights it in both graph view and in the nets table at the bottom of the window. In addition the Graph view also associates the simulation input and output files with the appropriate nets. The simulation input file associated with net0 is displayed on the right.

  2. In the graph view, select the file source that connects to net0, as shown in the previous image. The input data displays on the right hand side of the window.
  3. Select the kernel in Graph view, and switch to the Trace view to view the events and detailed event timing.

  4. In the events table at the bottom of the screen, select Buffer from the column selector.
  5. Type buf0 in the adjacent (filter) box.
  6. Core events that match buf0 are highlighted in the events table. Browse through the events if there are multiple events using the Previous/Next toolbar buttons to show the matched events.
  7. The highlighted data matches the data from the input file, shown in the right-hand pane.
    Note: The AI Engine kernel does not start until all the data is available at the window interface.
Use these steps to inspect I/O data for the required window connections. You can use this to ensure the correctness of the I/O data to and from a kernel.
