+**NOTE**
+
+ 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.
