## Summary

Donald Telian, founder of SI Guys and originator of the IBIS modeling standard, discusses the evolution of signal integrity from 'old school' transmission line theory to modern equalization-based design. He explains how IBIS-AMI models abstract complex IC behaviors to enable efficient simulation, while warning that model quality and correlation with measurement remain critical challenges. Telian also shares insights from his consulting career and his multidimensional training approach, which includes in-person classes and running.
