RE: [IBIS-Users] SERDES in IBIS

"Caveat" may have been a better word than "drawback".  I'm not
personally aware of any drawbacks.

Hello Sivaram,

IMHO, I believe [driver_schedule] can be made to work with only minor
drawbacks (maybe Arpad can elaborate on those).  But multi-lingual will
definitely work for this generation SERDES, as well as most any
challenge future technologies may bring (dfe, slew dependant timing,
ssn, automated measurements, etc, etc).  And, with AMS support
anticipated on over half the board-level SI market before the end of the
year, your investment in multi-lingual should pay attractive dividends
now and well into the future.  

Gary

Hello Experts,

Can we model SERDES(working at 4Gbps) with IBIS using [Driver_schedule]
feature (or) we should depend only on multi-lingual extensions of IBIS?

The SERDES i'm talking about has control signals to change the
pre-emphasis percentage, control signals to change amplitude etc.

Thanks in advance,
Sivaram
