Abstract
IBIS (input/output buffer information specification) models are known to lack information regarding power and ground bounce resulting in incorrect simulations. In this paper, a novel solution to the problem is proposed making it possible to simulate IBIS models with available simulators and have a realistic chance at simulating simultaneous switching noise (SSN) that are present in most if not all high speed circuits. To demonstrate the solution, a CMOS voltage-mode driver circuit and a current-mode LVDS driver circuit are simulated using HSPICE and compared with equivalent circuits created with IBIS models of the same drivers. The IBIS models are created using the s2ibis tool from North Carolina State University.
