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

If Electrical Routing is activated, the interface checks the CNS_CON_GR connection point attribute and groups ports that share the same attribute value.

Limitation: This attribute is sometimes used to logically group ports by their role (in,out), resulting in all input ports (e.g.) being converted to a single multiport. A partial mitigation of the limitation is the ability to configure the grouping attribute with the "TerminalGroupMarker" key in ifugnx.cfg so that the interface will take the correct attribute for each catalog where it is specified.
