TINA/Spice: How to use two or more GROUND connections in TINA?

Tool/software: TINA-TI or Spice Models

My application is build around a transmission line, having a transmitter and receiver at either ends. Both of them are isolated from Tranmission line using transformer. I have overall model ready but the problem is the system practically does not share the same ground. How do I simulate with two different grounds? Or is there any to isolate the grounds? Please share your opinions, thanks.!

    Hello,

    I'm thinking that maybe you can tie all the Receive side common connections together and drive that common / single node with a voltage source of your choice. This voltage source could then be a DC, AC, or noise source depending on what you think the major difference between the Send / Receive grounds  is or what you like to simulate.
