Abstract

We consider the problem of minimizing the delay intransporting a signal across a distance in a VLSI circuit. Theproblem can be restated as a combined buffer insertion,buffer sizing and wire sizing problem. We propose a simplebuffering architecture for this problem and show thatthis architecture achieves a near optimal solution. We alsoderive simple models for a buffered wire which are suitablefor high level design.
