RE: min and max rising/falling waveforms in s2ibis2

Betty,
 
There's one more reason not to use s2ibis2. Someone needs to come up with a
good tool to do this. The few I know of are internal to the companies that
create them, except for the one commercial IBIS creator tool from Applied
Simulation Technology. Are there any others?
 
Good luck,
Weston

Subject: min and max rising/falling waveforms in s2ibis2

Hi,
 
I am using s2ibis2 to generate my IBIS model. I have set the [Voltage
Range] to be 3.3 3.0 3.6 (typ, min, max). The IBIS cookbook suggests that a
50 ohm resistive load Vdd be used for the rising and falling waveform VT
data. In the s2ibis2-generated Spice files, the 50 Ohm load always
connected to 3.3V, even for the min and max case.
 
Is this the correct behaviour? And if so, why are 3.0 and 3.6V (for min and
max respectively) not used?
 
I would appreciate any feedback.
 
Thanks,
Betty Luk
