Hi Glenn, The command completes without showing any error and also shows a plot but the values are all zeros. Except for the case when it shows up. Do you have related problem before? In simulation, all seems fine, but to check it again, I am going to compile the design with known inputs instead of using x64_adc for the inputs. Thanks.
