The vcdanalyze
utility is provided to generate an AI Engine
event trace from the VCD file. This process is integrated into the Vitis tool flow automatically. From the Vitis IDE, after a simulation run has finished
capturing AI Engine events, you can right-click
on the project from the Explorer view and
select Analyze AIE Events. The trace data is
produced under the current project at trdata.aiesim/ and various views are automatically loaded into the
current project.
The raw event trace under the directory trdata.aiesimevents.txt should look like the following:

The following command produces the AI Engine trace data for foo.vcd in text form in the ./trdata.aiesim/events.txt file.
vcdanalyze -vcd foo.vcdvcdanalyze -h to get help for the command. The following command produces a CSV file from the AI Engine trace data from the foo.vcd file.
vcdanalyze -vcd=foo.vcd -csvvcdanalyze -vcd foo.vcd -wdb
