Hi,
I'm looking at trying to model a SerDes with pre-emphasis in IBIS using a
driver schedule approach. My signal has 4 levels: high-high, med-high,
med-low, and low-low.
The output is CML. My question is how do I extract the correct IBIS data
for each level? For example, how do I get the I/V data for just the
high-high state? The pre-emphasis is only
for one bit period. Would I use a long clock so it stays high-high long
enough to get the data? Any examples, articles, info would be appreciated.
Regards,
Tim
