How can I connect multi bits to one bit?

    There is an output pin, a<12:0>, in one of my symbol. I want to
    connect some of the wires, say a<12:9>, to a single pin of another
    symbol. How can I do this without getting an error ? In the very old
    "compass" system, I can easily do this by giving the same net a
    different name (alias) with the "alias" symbol. I was wondering if I
    can do the same thing in Cadence's composer. Any suggestions? Thanks!

    Just tap those bits from your bus (ie draw a wire and add label a<12:9>), then connect to the pin.

    It will complain that outputs are shorted together - this is just a warning, change port type to
    inputOutput in order to avoid it.

    Read the composer user's manual for more info, there's a whole section about this.

    cheers,
