Referencing Parameters in Node Notes
You can edit node notes as text to include the following references to other parameters:
Node name, for example, &node_name
Node parameters, for example, &signal_name
Top-level symbol parameters, for example, &ref_des
Any valid drawing parameters included as labels, for example &scale
 
* You can reference only those symbols to which you have assigned values in the symbol parameter set. If you delete a parameter that a note references, "***" appears in the note instead of the missing parameter value.
