If you want to use your own stimulus input file, specify it in the Set Parameters dialog box when creating the ADC IP.
Enable the Enable user created expected output file option (in Logic Simulation) and specify the created stimulus input file in the Use created expected output file field for each channel to be used. For each channel used, specify the created stimulus input file in the Use created expected output file field.
