Why can I not connect up the s_axis_video_aresetn and m_axis_video_aresetn signals from the XPS GUI?
This is because the "s_axis_video_aresetn" and "m_axis_video_aresetn" signals are associated with their respective busses and the adjacent cores do not have these signals.
XPS shows these signals as unconnected, but they will be tied high by default if they are not connected.
If you need to connect them, you can do so by modifying the MHS file.
The following 2 lines are an example:
Note: The recommendation is to connect the signals to a reset that is synchronous to each of the respective clock domains.
