Hi,

I got a very stupid question. What is IBIS, IBIS model ???
 

IBIS is the Input/Output Buffer Information Specification from the Electronics Industry Alliance. It is a modeling technique that provides a simple table-based buffer model for semiconductor devices. The IBIS models can be used to characterize I/V output curves, rising/falling transition waveforms, and package parasitic information of the device.
However, it is important to note that an IBIS model is intended to provide nonproprietary information about I/O buffers; it is not a delay model for timing analysis purposes.

Attached is an technical brief from Actel that talks about IBIS.
 
Hi all,

Asking simple question like this one is not stupid, but lets begin a serios talk and disscusion instaed uploading files many times.
I was looking for a book(s) witch is dealt with this issue in acadamic manner not as AN.
Any suggestion?
 

Digital Techniques for High-Speed Design by Tom Granberg has a chapter that talks about IBIS.
 

Here is everything you need about IBIS

Thanks for asking! The IBIS Open Forum's official website is:

Most of our documents, plus a summary of our history, is available at:

Can some1 teach me how to analyz those waveform? (GROUND CLAMP, POWER CLAMP, PULL-UP, PULL-DOWN, RISING and FALLING)
 

Tok47,

That's tricky, as there are many details. However, free training is available on-line at the IBIS website:

Several versions of "Introduction to IBIS Models and IBIS Model Making" are posted there. Look under the "streaming" directory for a video version, with audio!

Additionally, many tool vendors offer whitepapers and training materials on IBIS, particularly on their own implementations of it. Ask your vendor for details.
