Crosstalk Avoidance Method Considering Multi-Aggressors

초록

This As manufacturing technology scales to smaller dimensions, wire size is increasing and spacing between wires is decreasing, the influence of interconnect becomes dominant factor. Coupling capacitance between wires induces crosstalk. Crosstalk causes functional and temporal problem. In this paper, we propose timing window shift method considering multi-aggressors to reduce delay degradation. We assume that crosstalk induced delay degradation is proportional to coupling capacitance and timing window overlap. In this assumption, we model Aggressive Factor which represents the amount of crosstalk induced delay degradation. Proposed method is experimented with ISCAS85 benchmark circuit. We have a result that average of 4.85% crosstalk induced delay degradation minimization.
