FreeLists / si-list / [SI-LIST] Re: Eye diagram measurement

[Vinu Arumugham <vinu@xxxxxxxxx>]

StatEye takes a few minutes to generate an eye diagram from 
S-parameters. It too includes crosstalk effects. StatEye also includes a 
DFE.
It may take hours though for a simulator to generate the S-parameters or 
TDT/pulse response of the channels.

Thanks,
Vinu
