+   When running spice extraction on the user_analog_project_wrapper layout, it is recommended to use `ext2spice short resistor`. 
+   This is to preserve all the different port names in the extracted netlist. In case you have two ports that are electrically shorted
+   in the layout, the `short resistor` option will tell magic not to merge the two shorted ports instead it adds zero-ohm ideal resistors 
+   between the net names so that they can be kept as separate nets.
