NX Routing Electrical supports grouping of multiple terminals (pins) in a singe multiport.

When Electrical Routing is enabled, the interface will check the CNS_CON_GR connection point attribute and group Ports sharing the same value of this attribute.

Caveat: Sometimes this attribute is used to group ports logically by role (in,out), resulting in every input port (e.g.) converted to a single multiport. A partial mitigation for this is the possibility to configure the grouping attribute with the "TerminalGroupMarker" ifugnx.cfg key, so that the interface will use the correct one for every catalog where it is specified.
