 address is either the name of an <i>abstract network</i> or a pair of
 <i>abstract component</i> and <i>port name</i>, e.g. CN2-4 means "port 4
 of component CN2".

+Note: <i>port name</i> means the name the port is listed by in the abstract
+model, which is typically the original terminal name, and not the
+"pin number", or the calculated display/name attribute. For example using
+a polarized symbol, e.g. a diode it is typically A and C (not 1 and 2);
+or using a transistor symbol, the port names are B, E, C (and not 1, 2 and 3).
+Tip: switch to the raw view to reveal the original port names or use the
+abstract model dialog to find them.
