WARNING: [Vivado 12-1609] Net (net name) is marked DONT_TOUCH by the tool (not by the user), and it cannot be unset.
Resolution: If the net is set as MARK_DEBUG, then MARK_DEBUG must be unset to remove the DONT_TOUCH
WARNING: [Vivado 12-1609] Net ‘u_demo/sdi_R[1]’ is marked DONT_TOUCH by the tool (not by the user), and it cannot be unset.
Resolution: If the net is set as MARK_DEBUG, then MARK_DEBUG must be unset to remove the DONT_TOUCH
The issue originates from Vivado setting some nets as ‘don’t touch’ and not allowing for subsequent changes.
Re-synthesizing the projet and re-starting the process of inserting the debug core usually solves the problem.
