Enhancement of IBIS modeling capability in simutanous switching noise (SSN) and other power integrity related simulations - proposal, implementation, and validation

IBIS models are widely used in I/O related signal integrity simulations. This paper points out the problems with the present IBIS model in power integrity related simulations. A new proposal of adding some additional information to the existing IBIS standard to expand its capability in SSN and other power integrity related simulations are introduced. The processes to extract this information from transistor-level Spice model and implement the new proposal in existing IBIS tools are illustrated by using an example in HSPICE. The accuracy of the new proposed model is verified in simulations with nonideal power supply
