Abstract

In this tutorial we discuss concepts and techniques for the accurate and efficient modeling and extraction of interconnect parasitics in VLSI designs. Due to increasing operating frequencies, microwave-like effects will become important. Therefore stronger demands are put on extraction and verification tools. We indicate the state-of-the-art for capacitance, resistance and substrate resistance extraction and discuss some open problems. We also discuss several model reduction techniques as well as issues related to simulation and implementation in a CAD system.
