dual curve issue for input pad

Dear IBISers,

    I resend this mail because the previous one seem to have some
problems.

    I am currently involved in the design of a I/O pad and building IBIS
for it, but I am facing some troubles, my I/O
pad has dual I/V curves while in input mode, that is, the I/V curves for
rising input and falling input are
different. IBIS seems to not supporting this kind of design, and s2ibis2
will not generate correct model for this. Is
there any workaround? Any comment is welcome.

Best Regards
