Objectives
• Compare SI Tools using IBIS models
• Compare to empirical measurements and SPICE simulations
• All measurements and simulations performed on SI test boards created at EMC

Summary
• SI Simulators, using IBIS models, are complementary and accurate
• IBIS models need to be checked: beware of data sheet models
