Abstract : Modern Signal and Power Integrity SI-PI verification flows rely on accurate models for complex I-O-buffers that drive and receive electrical signals on high-speed channels.
The sheer density of modern integrated circuits makes detailed transistor-level descriptions computationally cumbersome to the point where they become unusable for system-level simulations.
Fortunately, transistor-level descriptions may be replaced with more compact representations that approximate the input-output buffers behavior with considerable accuracy while providing a simulation speedup of several orders of magnitude.
Known as behavioral models, surrogate models or macromodels, these computationally efficient equivalents have become a de-facto industry standard in SI-PI simulations.
This paper presents an overview of the state-of-the-art in I-O-buffer behavioral modeling, introducing the main features of both standard and emerging solutions.
Open issues and future research directions are also discussed.
