A wire routing scheme for double-layer cell arrays

Global routing for modern large-scale circuit designs has attracted much attention in the recent literature. Most of the state-of-the-art academic global routers just work on a simplified routing congestion model that ignores the essential via capacity ...

In an automatic routing system for macro-cell layout the wiring area is decomposed into a number of smaller regions. These regions are routed separately by a detailed router such as a channel router or a switch-box router. The position of the pins at ...

As the technology node advances into the nanometer era, via-open defects are one of the dominant failures. To improve via yield and reliability, redundant-via insertion is a highly recommended technique proposed by foundries. Traditionally, double-via ...
