+Note that both poly and gate are included in the connectivity. Even if gate is subset of poly it needs to be connected to poly. The poly layer will supply to connections to the gate and the gate layer will supply the gate shapes for gate are measurement.

 Diodes can be included to rectify the antenna effect. A diode is characterized by a layer which describes the diode area. Here is a sample for an antenna check with diodes:
