circle01_red.gif IBIS (Input Output Buffer Information Specification) ¶õ?

IBIS is a method of providing the Input/Output device characteristics through V/I data without disclosing any circuit/process information. It can be thought of as a behavioral modeling specification suitable for transmission line simulation of Digital Systems and applicable to most digital components.
