When two tristate drivers are connected through a splitter and one driver is in High-Z state, a pulldown resistor on the output net is incorrectly treated as causing a short/conflict rather than resolving the line to a weak 0.
This is incorrect behavior — in a real circuit, a pulldown resistor on a bus with tristate drivers is a standard and valid design. When all drivers are in High-Z, the pulldown should quietly pull the line low with no conflict.
