How do I debug multi-driven nets which are reported by Vivado Synthesis as follows:
You can try to debug using the HDL code mentioned by the message and try to find the conflicting drivers on that signal.
However, when the drivers are at different hierarchical levels in a complex and large design, it is much easier to use the elaborated netlist.
For a design in project-mode, the elaborated netlist can be opened from the GUI by selecting "RTL Analysis -> Open Elaborated Design".
In non-project mode, use the synth_design -rtl option.
Once the RTL netlist is loaded, create a schematic with the pins mentioned in the message and track down all drivers of the connected net.
