Hi Experts,

     

        I have a doubt on IBIS modeling regarding to V-T data using a
Signal Integrity tool.

Suppose if IBIS model contains V-T data generated for different
R_fixtures . how SI engineer is able to make the tool to use required
R_fixture data  from all  V-T tables?



 As an example if I am generating V-T data(2 Risings and 2 Fallings)
against 2 Rloads i.e RLOAD1 and RLOAD2  both are less than 100 Ohms,
then s2ibis3 will put V-T will be in the below following order based on
assumption  RLOAD1 > RLOAD2



Rising  connected VSS  using RLOAD1

Rising  connected VDDS  using RLOAD1

Rising  connected VSS  using RLOAD2

Rising  connected VDSS  using RLOAD2



Falling  connected VSS  using RLOAD1

Falling  connected VDDS  using RLOAD1

Falling  connected VSS  using RLOAD2

Falling  connected VDSS  using RLOAD2



 So how a person using SI tool will chose the required V-T table data
based on RLOAD1 and RLOAD2 ? or will these be taken care automatically
by the tool?



Thanks for providing information on this



Best Regards

Kiran Kumar
