Hi SI Guru:
We are trying to do some Hspice simulations on SCSI bus to
investigate signal quality. One problem that we encountered is the
convergence
problem of Hspice. We are still not sucessful in bringing the spice
simulation to converge after we have tried different convergence aids as
suggested in
the Hspice manual. We plan to replace most of the receiver models with
passive lumped models ( i.e. one resistor and one capacitor for CMOS input
buffer ) and see whether this will help. Can anyone suggest what an
equivalent model will be for a LVDS input receiver will be? Any suggestion
will be appreciated.
