transient analysis can;t get desired waveform

[st127]

Im trying to do simulations on crosstalk  and voltage reflection.My assignment requires me to do a study and obtain the waveforms.However when I perform transient analysis on my simple circuit design I Cant get the desired waveform to show crosstalk and reflections.I need help badly...Ive attached the pictures of my circuit design and the desired waveform for reflections.Thank you

Unfortunely, your pictures did not post. Maybe you could try posting them again and we will see if we can help you out.
