[IBIS-Users] RE: [IBIS] input signal for model usage

Hi,

The OUTPUT of I/O ( IBIS model)  does not depend on the Rise/Fall slew
at the input of I/O ( say A_in ).

 

If you mean. Can you have different  LOW/HIGH duration? 

You can give different clock/pulse frequency, but there is an upper
limit of the clock.

The upper limit of the clock frequency is limited by the duration of the
V-T tables/Ramp time.

 

Thanks,

Muniswar

Hello IBIS experts, 

 

 Once an IBIS model has been created, can be used in different Input
speeds?

 

 In other words: if I consider an I/O model, Can I use every input Pulse
with

 several rise/fall time Or I have to use only the same pulse used in the


 model creations?

 

I hope is clear what I mean.

 

Thanks,

Fabio
