Before revision: Usage of three-state logic is not recommended for on-chip connections but rather for inter-chip connections.경종민, On-Chip Buses/Networks for SoC "On-Chip Buses [have] No use of tri-state signals [because] Tri-state bus is difficult for static timing analysis" Three-state buffers used to enable multiple devices to communicate on a data bus can be functionally replaced by a multiplexer.
