Schematic connection

Ah that's what you meant, if you just one individual wires off a bus you can just use a subscript of [x] to pick it off. I used to do this all the time when I wanted to invert certain lines of a bus, I would just pick off the ones I wanted, invert them, then alias them back to some new bus alias. So in your case you can just use wires and pick off the bus lines using "DATA[0]", "DATA[1]", .... "DATA[7]". Those don't need to be bus lines using the 0..0 or 7..7 type of convention, if you index a single line of a bus you can wire it up to a regular schematic wire.
