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?
Thanks for your help Andrew! I think I can use this. The only slight limitation is that I need to specify X,Y coordinates (ideally, I would just like the layer to be labeled regardless of its location), but I think we can probably make an assumption that the origin will probably be contained within the extent of the design (since substrate is defined everywhere). If you know how to do this (label a layer without specifying coordinates) off the top of your head, please let me know. Otherwise, no worries - I think this will work.
Thanks again for all your help!
