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.
  1. Open the two summary files to be compared.
  2. Select the Trace view for either design and select Compare > Select To Compare 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. 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.
