Orcad express question

Guest
I'm a Viewlogic guy just using again Orcad after a long hiatus from Orcad (SDT
was the last OrCad product I used)
I'm creating a part. I have tons of ground pins. The way I've seen it done is to
use zero-length invisible power pins, one for each ground pin, and then you
sprinkle them around the part. Isn't there a way to create a pin with multiple
pin numbers, without having Orcad complain that you have multiple pins with the
same name? I can't really use a bus because the pin numbers don't follow.
Also, I have power pins that need the same treatment. You know, the usual Vdd,
Vd, PVd thing on big ASICs so I can decouple each rail seperately...
I'm sure it's something simple, but the help is less than helpful on these
subjects. The problem is the 'pin with same name' error I'm getting. Will this
prevent netlist generation?

It is not an error but a warning. Go ahead and use the same name. The
netlist generator should not care.

I worked with a guy for many years who was into Volvos. I used to
tease him by calling them Fluffos ;-)

You would not want to do that with your secretary of state now, would
you?
