RE: Using Ibis models in hspice

I tend to agree with Steve. I realize that the some vendors consider how use
IBIS IP. It would be real nice if some one could present issues concerning
implementations so the user community at large could make tradeoffs between
simulator companies.
Recently I've worked on doing an IBIS implementation and as neophyte to this
have uncovered a whole bunch of issues that I know simulator companies may
have solved in different ways. Each method will have it's limitations,
assumptions, and applicability. I think the IBIS summit meetings would be a
good place to air this.

                    I disagree completely. I have been looking forward
                    to someone responding to this question all day.

                    I think that this reflector needs to go beyond what
                    the latest BIRDS are, or whats going on with a trade
                    show. No invective intended toward BIRDS or trade
                    shows.

                    This group is supposedly a group of IBIS experts, which
                    likely have expertise as it relates to the question
                    below.
                    
                    I don't understand how the question posed violates the
                    reflector's purpose.
