Arpad, If there is a (1:1) correspondence between Pins and Die pads, and we are qualifying the Terminal with Pin_Name and Pad_Name, then (Connection #) is not necessary. However if there is no (1:1) correspondence of Pins and Pads, we cannot rely on the Pin_Name == Pad_Name to identify that the Pin and Pad are connected. I use (Connection #) , (Aggressor #) or (Victim #) to identify Terminal that are connected when using Model_Name in Terminal records. Two Terminals are "Connected" if there is a relatively low impedance connection between the two Terminals at Nyquist. Normal this would be a <~1 Ohm DC resistance between the two terminals, but this is not the case when there is a blocking cap in the circuit.
