Port numbering question.

Question asked by MartyM on Jan 30, 2015
Hi,
I've only been using ADS for a short while, but I'm getting these port warnings for ports 8 and 9.

--- WARNING -------------------------------------------------------------------

The distance between the layout pins for port 8 is electrically large 
above 18.2725 GHz, S-parameters may become unphysical.

The distance between the layout pins for port 9 is electrically large 
above 5.6223 GHz, S-parameters may become unphysical.

In my layout I have set up only 7 ports (based on edge pins).  How do I determine which port the warnings are for?  Am I correct that these ports are mapped to the schematic some way? Can I see their respective number scheme?
I have a simple subtrate. One conductive layer and a cover below that with a specified dielectric and spacing. So the ports are referenced to GND.  I will replace the cover with a "ground" conductor once I'm sure the setup is good and the results are reasonable.

Thanks.
