sunjimmy said:It depends on your design.
If the bus is shared within a small block, perhaps mux isn't a bad idea. But if the bus is shared by some blocks which may be placed seperately in layout, tri-state style is more suitable for area/routing consideration. And some small bus keeper may be needed.
Hope it helps : )
