RE: [IBIS] About Some IBIS Specifications

Yasser,
 
While the model behavior should not be affected by the parameters you
list below, I would not conclude that "no action is assumed to be taken
from the simulation tool" towards these parameters.
 
Some simulation tools use many of parameters to adjust results from a
system simulation, to produce a spreadsheet or other summary of system
timing margins.  The first bullet you show, in particular, lists items
commonly used for this purpose.
 
So, while tools may not change how they simulate the IBIS *buffer*
tables due to these parameters, changing these parameters may produce
different *system* analysis results.

Subject: [IBIS] About Some IBIS Specifications


Dear all,

I want to make sure from some IBIS specifications if you don't mind

I understand that the blow listed subparamters or keywords don't affect
the simulation results (or simulation procedure carried out by the
simulation tool). I want to make sure that no action is assumed to be
taken from the simulation tool towards the below listed
keywords/subparamters : 




*	Vmeas, Vref, Cref. Rref, Cref_rising, Cref_falling, Rref_rising,
Rref_falling, Vref_rising, Vref_falling, Vmeas_rising, Vmeas_falling,
,Rref_diff, Cref_diff under [Model Spec] 
*	[Temperature Range] 
*	[Test Data] 
*	[Test Load] 

Your feedback is highly appreciated

Thanks & BR,
Yasser Sabry
