Resumen

Signals in modern integrated circuits travel through complex interconnect structures, which present several layers and important coupling capacitance effects. Even more, the impact of signal coupling on the overall circuit behavior has grown with technology scaling as the interconnect have become taller. In this paper, a methodology to identify those logic paths more significantly influenced by the coupling capacitances is presented. The proposed methodology is based on a modified Dijkstra’s algorithm, which finds those paths between a primary input and a primary output more severely influenced by the coupling capacitances. This methodology can be used to validate circuit behavior and it can also be applied in testing techniques oriented to detect interconnect defects (e.g., opens and short defects). The proposed methodology is applied to ISCAS’85 benchmark circuits to show its feasibility.
