Driver Models<br />
� Need to accurately model Signals<br />
<strong>and</strong> dPPower<br />
� Obtain transistor level models if at<br />
all possible<br />
� IBIS tends to be pessimistic<br />
because current scales linearly<br />
with ihiincreased ddi drivers<br />
� Verify waveforms for single<br />
driver AND during SSO<br />
