Hi, I want to do differential TDR simulation in cadence virtuoso. I have a differential channel, made of Tlines and interconnects (passive componenets). How to setup the TDR simulation to get impedance over time? I know, I have to terminate both n and p channel with 50 ohm each at the output. I have to do also in the input. But how to connect the step voltage source or pulse generator at the input and get the recuiredimpedance over time from the channel reflection? Can anyone help me. Note: I am using virtusos version IC6.1.7-64b.500.4, there is no rfli. SO I cannot use Balun ports.![]()
