I am using a termination technique that is not one of the two automatically recognized techniques in CES to create electrical nets and differential pairs. I have a differential par going to a 100 ohm terminating resistor, but then each side is AC-coupled into the receiver pin with a series capacitor. CES looks at this termination and groups all four physical nets into a single electrical net! It is actually an electrical net made up of two differential pairs. I can separate the four nets out by designating some of them as "analog", but then I'm unable to use them in a differential pair since they're "analog".
Any ideas on defining electrical nets and differential pairs when the termination topology is not automatically recognized?
