Trace Compare in the Vitis Analyzer 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.
  1. Open the two summary files to be compared.
  2. Select the Trace view for either design, right-click and select Compare to > <filename>_summary for the other the design, or click on the Compare link. The compare can start from any trace.

    Note: In Trace Compare mode, features in the Vitis Analyzer apply to both Trace views.
This example uses the same design but one has added printf() statements in the kernel. By looking at this Trace Compare example, you can see that the upper design expended time on the printf() calls that slowed down the overall execution of the design.
