I'm having difficulty creating the power rails/rows in a floorplan with a macro. I'm basically using the storage macro from caravel and using the pdn.tcl: https://github.com/efabless/caravel/blob/master/openlane/storage/pdn.tcl However, it gives an error like:
Copy code
[WARNING PSM-0019] Voltage on net vccd1 is not explicitly set.
[ERROR PSM-0020] Cannot find net vccd1 in the design. Please provide a valid VDD/VSS net.
Error: or_pdn.tcl, 36 PSM-0020
