New ContributorSignalTap cannot capture the output of ALTDDIO.
No, it's because Signal Tap can't connect directly to I/O outputs because there's no signal wire back into the core to connect to Signal Tap. You have to tap whatever is feeding into the output, like data_h and data_l as you mention.
In the Node Finder, when adding signals to Signal Tap, you should be using one of the Signal Tap filters. This makes sure you tap only signals that are "tappable" to Signal Tap. Outputs would not show up in this filter.

New ContributorAlright, what I understand is that I cannot directly capture the output of DDIO, but can have an appropriate external processing for this signal and then capture it indirectly. Thank you for your response.
