To generate a VCD file from the Vitis IDE, right-click on your AI Engine graph project from the Explorer view and select as described in Creating the AI Engine Graph Project and Top-Level System Project. This opens up the Run Configurations dialog box for the current project.
Select the AI Engine Emulator option and double click to open a new configuration. Select the Generate Trace check box to enable trace capture, and select the VCD Trace button. By default, this produces a VCD dump in a file called foo.vcd in the current directory. You can rename the file if you like.
The VCD file can also be generated by invoking the AI Engine simulator with the
<filename> option on the command line. The VCD file is generated
in the same directory as the simulation is run. Assuming that the program is
compiled using the AI Engine compiler, the
simulator can be invoked in a shell with the VCD option.
$ aiesimulator –-pkg-dir=./Work --dump-vcd=foo
This command produces the VCD file (foo.vcd) which is written to the current directory.
