Window data analysis in the trace
view allows you to cross probe from a specific input/output window net connections in
the graph view to the appropriate position in the event trace view. You can trace window
input data as it is being buffered prior to the kernel starting execution. To perform
data analysis on a window interface, use the following steps.
- The following image shows a net connection that has been selected in the
Graph view. The
selected net (
net80
) is highlighted both in net 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 withnet80
is displayed on the right.
- In the upper net view, select the file source that connects to
net80
, as shown, circled in the previous image. The input data is displayed at the right hand side of the window. - Switch to the Trace view to view the events and detailed event
timing.
- In the events table at the bottom of the screen, select Net from the column selector.
- Type
net80
in the adjacent (filter) box. - Net events that match
net80
are highlighted in the events table. Browse through the events using the Previous/Next toolbar buttons to show the matched events. - 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.
Using these steps, you can inspect I/O data for
the required window connections to ensure the correctness of the I/O data to and from a
kernel.
