Help using QuartusII

Or just do it directly:

in[31..0] ..... then when you need those bits just use a bus of in[1..0]

If you want each signal separately, then you use in[1] and in[0] (or you can wire these to another alias).

That's the reason for naming signals (called aliasing), so that you can bring signals everywhere without having to directly connect them in your schematic (this is true with all good schematic software).

Use the wire component if you want to rename in[1..0] to something more descriptive if you need that (wire basically associates two net aliases together without causing an error).
