Hi,

If Timing Measurement Conditions describing parameters (Vmea= s  Rref  Vref  Cref ) are included in a model,

Does this imply that the delay ( core i/p to pad ) of IBIS or SPICE Buffer  with this load conditions and measured at Vmeas will be same. =

      = Tdelay (Vme= as  Rref  Vref  Cref )  (IBIS)     =3D  Tdelay (Vmeas  Rref  Vref  Cref )  (SPICE/Lab measurement)    

         Tdelay = <=3D  Delay from input to Pad

 

         &n= bsp;         

With regards,

Muniswara Reddy . V

Design engineer, PIPD-IO group,

Please note that traditional IBIS (i.e., IBIS based on tables of I-V and V-t data, plus C_comp) does not include any information about the buffer's stimulus from the core, latches, die logic, etc. So, the timing measurement parameters Rref, Cref, Vref and Vmeas do not characterize Tco, Tvalid or any clock-to-output or core-to-output behavior. The IBIS timing measurement parameters only describe the load used to characterize the time taken by the output to reach the given measurement level (Vmeas) from the stimulus edge presented to the IBIS model by the simulator. Therefore, you may see a difference in delay time between the output from a SPICE transistor-level model and an IBIS model of the same buffer into the same load. The overall shape of the waveform after the transition begins should be identical, however, depending on the quality of the IBIS model. Some good presentations on these topics can be found on the IBIS website at: http://www.eda.org/ibis/training/ I hope this helps! - - Michael Mirmak Intel Corp.

Dear Experts,
 
I have a question regarding IBIS models.
We have an IP that is just a short with only ESD diodes connected between supply rails.
There is no input or output section in this IP.
Would it be possible to generate IBIS models for such an IP ?
If yes how should it be done ?

You could consider using the

"Terminator" model type.

Dear Experts,

 

I have a question regarding IBIS models.

We have an IP that is just a short with only = ;ESD diodes connected between supply rails.

There is no input or output section in this IP.

Would it be possible to generate IBIS models for such = an IP ?

If yes how should it be done ?

 

Thanks

Ajay
