    7. Simulation on component boundaries: the IBIS model

    7.1 History and role of the IBIS standard

    The IBIS (Input/OutputBufferInformationSpecification) model was created by INTEL to provide its customers with the characteristics of input/output circuits, without revealing any technological information, enabling signal integrity simulations to be carried out at PCB level. Compared with physical models, running an IBIS model saves considerable time, thanks to the simplicity of the electrical elements involved. It corresponds to boundary macromodeling.

    The IBIS model was standardized by the Electronic Industry Association (EIA) in 2005. In order to keep pace with the explosion in data rates on communication buses between components (figure
