Stream data analysis in the trace
view allows you to cross probe from a specific input/output stream net connection in the
graph view to the appropriate position in the event trace view. You can trace stream
input data as it is being received during the kernel execution. To perform data analysis
on a stream interface, use the following steps.
- The following image shows a kernel port that has been selected in the
Graph view. The
selected port with ID,
pi0, is highlighted both in the Graph view and in the net table at bottom of the window.
- Switch to the Trace to view the events and detailed event
timing.
- Move the time marker to the beginning of the stream data by dragging the vertical line (time marker) in the upper part of the window.
- In the upper part of the window you can examine the data associated with the selected input port.
- In the events table at the bottom of the screen, select Data from the drop-down menu.
- Type
0.000000+0.000000iinto the adjacent (filter) box and click Next. The expected time and data are highlighted in the events table.Note: The input value depends on data type.0.000000+0.000000iin this example is for a complex float type.
Using these steps, you can inspect I/O data for
the required stream connections to ensure the correctness of the I/O data to and from a
kernel.
