Effect of Distributed Shield Insertion on Crosstalk in Inductively Coupled VLSI Interconnects

Abstract

Crosstalk in VLSI interconnects is a major constrain in DSM and UDSM technology. Among various strategies followed for its minimization, shield insertion between Aggressor and Victim is one of the prominent options. This paper analyzes the extent of crosstalk in inductively coupled interconnects and minimizes the same through distributed shield insertion. Comparison is drawn between signal voltage and crosstalk voltage in three different conditions i.e. prior to shield insertion, after shield insertion and after additional ground tap insertion at shield terminal.
