How can I connect multi bits to one bit?

[Tao Chen]

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!

Does Composer support a "synonym" symbol? If so, it'd be the same
functionality as the "alias" symbol you once used...

Just tap those bits from your bus (ie draw a wire and add label a<12:9&gt, 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,

Stéphane
