[sci.electronics] ViewLogic WorkView Bus Problem

watt@eleazar.dartmouth.edu (Gill Watt) (05/01/91)

howdy,

Perhaps you folks can help me on this problem we've been having 
with WorkView.  

The problem has to do with buses and the "Net has two names"
error.  

A simple example of this problem is when we try to connect
a single net on a bus to ground.  The ground symbol is simply
defined with a net name of "GND" so when we try to label the
net the name required to connect it to the bus, we get the 
error message: "Net has two names."  

At the moment we get around the problem through the use of a 
buffer (/lib/builtin/buf.1).  This works o.k. for simulation
but it sure doesn't netlist correctly.

Is there some other way around this problem?

What do you want the net to be named?  GND?  Or the name of the label?
You can't have both.  (Without getting a Warning.)

If you want it to be GND, you could just use TEXT instead of LABELs for
the net names.

If you want it to be the name of the label, and not GND, you could create
your own GND symbol that isn't really a GND.  (Scary, but possible.)
