Tracing cascaded data is similar
to trace stream data. Cascade data analysis in the trace view allows you to cross probe
from a specific input/output cascade connection in the Graph view to the appropriate position in the
event trace view. You can trace cascade input data as it is being received during the
kernel execution. To perform data analysis on a cascade 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,
pi2, is highlighted both in the Graph view and in the ports table at bottom of the window.
- Switch to the Trace
to view the events and detailed event timing.
- View the data associated with the selected input port.
- In the events table at the bottom of the screen, select Data from the column selector drop-down menu.
- Type
25110763into the adjacent (filter) box and click Next. The expected time and data are shown in the events table.Note: The input value depends on data type.-25110763+586082921iin this example is for a complex integer data type.
Using these steps, you can inspect I/O data
for the required cascade connections to ensure the correctness of the I/O data to and
from a kernel.
