NET diff_net
  NODE U1 1
  NEXT 1.0 Z: 55. S: 2.0
  FORK 0.0
    SERIES R1 I1 TYPE R100
    NODE DUMMY 1 TYPE NOP NO_DISPLAY
    NEXT 1.0 Z: 55. S: 2.0
    NODE U1 2
  ENDFORK
  NEXT 0.2 Z: 55. S: 2.0
  SERIES U2 1 TYPE LVDS_DIFF_IN 2 POS
  NEXT 0.2 Z: 55. S: 2.0
  CONNECT_NODE DUMMY 1
ENDNET

The CONNECT_NODE makes a connection back to another node in the topology.
