    Is there a way to draw a bus in virtuoso? What I mean is that I have
    to draw a 15 bit bus and would rather draw all 15 lines at once. Right
    now I have to draw each one individually. Is there a way to draw all
    at once?

    You just label it using the bus notation, such as A<15:0>.
    You can also draw a thick wire if you want some visual clue that the
    wire is a bus (but it's purely visual).
    Check the User manual for the various interactions between buses, single
    nets, instance terminals etc..

    cheers,

  3. I think jbrand wants to know, how to draw a bus in layout,
    not in schematic composer

    Aaaah.. are you sure ? Well anyway, in that case then this facility is
    available in virtuoso XL with the wire editing enabled (i.e the
    create->wire command). In this mode you can select multiple pins at once
    and draw the wires in one shot as a bus.

    cheers again,

  5. You can try a bit with
    a multipart path.

    In Virtuoso: Create -> Multipart Path + (F3 key)
    the click to Subpart in the options form and figure out what fits for you.
