IBIS model formulation and extraction for SPI evaluation

Abstract

This paper presents an analysis and extension of the input/output buffer information specification (IBIS) model's formulation and extraction based on the buffer issue resolution documents (BIRD) 98.3 and BIRD 95.6 to improve the signal and power integrity (SPI) prediction and evaluation under simultaneous switching noise (SSN) scenario. The performance and accuracy of the proposed model are evaluated in a SSN validation setup composed of three drivers.
