AI Engine emulator output files from the design are located at ${PROJECT}/Emulation-AIE/aiesimulator_output/data. Verify the output files ${PROJECT}/Emulation-AIE/aiesimulation_output/data/dlbf_out[0-7].txt and ${PROJECT}/Emulation-AIE/aiesimulation_output/data/ulbf_out[0-3].txt against golden files ${PROJECT}/data/dlbf_gold[0-7].txt and ${PROJECT}/data/ulbf_gold[0-3].txt to ensure that the design’s I/O functionalities are correct. Vitis™ IDE supports the compare with feature to compare two files, highlight the files to be compared, then right-click one of highlighted files, and select compare with > each other with transformation > Predefined filters > Remove timestamp.
Selecting each other with transformation is required because AI Engine emulation inserts a timestamp for each output data.
