RE: [IBIS-Users] LVDS buffer IBIS generation

Tom, what capability are you referring to?

As described on pg. 36-38 in the Cookbook, the data can be modeled
with the [Series MOSFET], [Series Current], [R Series] keywords which
have been available in the IBIS specification for years.  It is a 
different story that not all simulators may be supporting them yet.

If you read the IBIS spec you will find that capability has not been
added
yet.  And if it was there is likely no simulator that would take the
data
anyway. You can best add that level of detail by adding an external
SPICE
model to the file.  Use IBIS Version 4.2.

Subject: [IBIS-Users] LVDS buffer IBIS gereration

Dear experts,

I read from one paper " Details on True Differential
Buffer Characterization Revisited" by Aprad Muranyi of
Intel Corp, And I used this method to generate the
differential and common mode I-V curves and the V-t
curve for one differential LVDS buffer.But I don't
know how to convert these data to the formal IBIS
format, and using which version to verify the IBIS
file. 
Can some IBIS experts give me more detailed
information about it, or Could share some examples of
LVDS IBIS file to study the format, it is still look
like the single ended ibis file? how many data we need
to pick?

I'm really appreciated for your kindly help!

Thanks

bi
