ID:21199 LVDSOUT port of LVDS DPA atom "<name>" must be fed by output pin that does not feed any other logic

CAUSE: The LVDSOUT port of the specified LVDS DPA atom is driven by something other than an output pin that does not feed any other logic. However, an output pin that does not feed any other logic must feed the LVDSOUT port of the LVDS DPA atom.

ACTION: Modify the design so an output pin that does not feed any other logic drives the LVDSOUT port of the LVDS DPA atom.
