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.
-------------------------------------------------------------------------------
--- WARNING -------------------------------------------------------------------
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.
