Further configuration options include:

1. Change IC model to Fast/Slow

2. Use package or not.

3. Change the Model selector to a different pin or voltage level. When you increase the model logic level here, increase the Pullup value to the same.

4. Change V_IN. For the RX_D pins, use a PRBS source, found in the Sources-Time Domain palette.

To replace the transmission line with custom S-Parameter models, search for the SnP component in the search bar and connect it in place of the ideal transmission line.
