ibis-spice conversion in win98

Dear All
        I have some questions about SDRAM IBIS model creation.
1. Can I use Hspice (DOS ver) and s2ibis2 (win95 ver) in win98 to make
ibis file?
2. Where can i find examples which close to SDRAM's *.s2i file, Because
i don't know how to write a *.s2i file correctly?
3. What's the relationship between *.sp, *.spi and *.s2i in the step of
making ibis?
4. If i want to extract the ramp rate data of SDRAM (LVTTL), what kind
of input waveform must be applied to
    the input node (perfect step function from 0-3.3v (3.3v-0) or
1ns/1ns rise/fall time waveform) ?
5. How to define the v_fixture of LVTTL system and it will be added to
simulation the rising/falling waveform
     or not?

I need your help
thanks
Best Regards
Chris Hu
