RE: [IBIS-Users] IO, output, Input buffers

Mithlesh,

As to your second question, organize your model_selector section like
the following, 

[model selector]     io_type
IO models

[model selector]    output_type
Output models

[model selector]     Input_type
Input models 

Hope this helps.

Thanks,

Hello Experts,

I use [model selector] to select different models for pins. Few pins are
I/O, Output only and Input only.
The output only models do not have power/ground clamp curves and Input
only models have only clamp curves. i.e.
if i remove particular section, i can convert a IO model to output/Input
models, right?

Now, do i need to separately define Output & Input only models to
particular pins or I use the IO type model for them as well?

-----------------
[model selector]     io_type
IO models

[model selector]    output_type
Output models (or IO models ???)

[model selector]     Input_type
Input models (or IO models???)

-----------------

Highly appreciate your quick response.

Thank you!
Mithlesh
