Abstract

In this work, we present the crosstalk is a noise caused by inter-wire coupling capacitance between adjacent wires, and causes logic malfunctions and delay faults. Since the degree of crosstalk interference is determined by various factors, such as physical inter-wire coupling capacitance, length of wires running in parallel, switching speed of signals, and transition timing of adjacent signals, it is very difficult for VLSI designers to estimate the crosstalk influence in sufficient accuracy. In this paper, a technique for reduction of maximum bus delay caused by crosstalk is proposed. By approximated equation of bus delay, it becomes clear that our technique is effective for repeater-inserted bus. The result of simulation shows the total bus delay can be reduced.
