Trace Compare in the Vitis IDE allows the comparison of two different design
executions. The comparison between two design runs helps to see the impact of one or
more variances introduced in a design run. This allows you to inspect performance
difference regardless of what variables are adjusted.
- Open the two summary files to be compared.
- Select the Trace
view for either design and select and from the drop down choose the run summary of the other design
to start comparing the trace. The compare can start from any trace.
Note: When you change any of the IDE Trace options, it applies to
all the Trace views in the Trace Compare mode.
This example uses the same design but one has added printf() statements in the kernel. In this Trace Compare example, the
upper design expended time on the printf() slows
down the overall execution of the design.
