[SI-LIST] stimulus doubt - address simulation for DDR2.

Dear Experts

I have done the address simulation for DDR2.

When I give a stimulus using 200MHz oscillator waveform with 50% duty
cycle, I get a good waveform.

If I give a stimulus using PRBS pattern, I get a waveform with more
ringing.

Is it because of the topology error or ibis model?

I checked with another ibis model also. But the observations are same.

I am using HyperLynx 8.2.1

Please assist me to correct the waveform.
