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.

Walter,

 

Could you please explain what "(Connection xxx)" does on slides 9-12?

 

Thanks,
