Advanced Design System (ADS) global node?

Hi, I have a question about the Agilent Advanced Design System (ADS) global node?

I am wondering how can I use it? How can I define a "Global Node" at the root design, and use it also in the sub-design for supply voltage, such as "DC15V"?

And how about the "Power Pin" in the symbol definition? What shall I assign the property and value of the Power Pin?

Any information will be welcome. Thanks.

"Power Pin" of Agilent ADS is aiming at same function as "Inherited Connection" of Cadence Composer.
But implementation is fairly imcomplete.
I don't recommend you to use "Power Pin" of Agilent ADS.
