  • Identifying subsets of noise violators and contributors in package wiring
    Patent number: 5471397
    Abstract: A method for identifying a minimal subset of noise violator nets that can be removed to ensure that no net has quiet noise that exceeds a specified maximum noise. Nets and the coupled noise between them are initially represented in a weighted directed graphical representation. Each net is a vertex in the representation. If a net in its active state causes a coupled noise on a quiet net, there is a directed edge or vector from the vertex of the active net to the vertex of the quiet net.
