Assigning a Net Name to a Layer for LVS/RCX

LanceT

Does anyone know of a way to assign a specific net name to a layer for use in LVS/RCX?  We are using a process where the bottom layer of the design will be electrically connected to a signal "GND_SUB" and I want to be able to assign that label without having to create a physical connection to it.  I can create bogus connectivity for that layer just so that it is a "connected" layer that doesn't really connect to anything in the layout but is there a way to assign a specific net name to that layer?

    For RCX, being able to specify the substrate as the Ref Node is certainly part of it and I do have it set up to do that.  What I am looking for is a way to define a label for that node without creating a physical label in the layout.  That is what we are currently doing - we have to add a goofy bogus connection in order to assign the net "GND_SUB" to the substrate.  We would like to be able to have Assura LVS understand that the substrate layer will always be connected to net "GND_SUB" without having to create any sort of physical connection or even a label to it in the layout.
