On Routing in VLSI Design and Communication Networks

In this paper, we study the global routing problem in VLSI design and the multicast routing problem in communication networks. Firstwe propose newand realisticmodels for both problems. In the global routing problem inVLSI design,we are given a lattice graph and subsets of the vertex set. The goal is to generate trees spanning these vertices in the subsets to minimize a linear combination of ove...

A Review on Channel Routing On VLSI Physical Design

We know that channel routing is very important problem in VLSI physical design. The main objective of a channel routing algorithm is the reduction of the area of a IC chip. In this paper, we just do a survey on some impotent multi-layer routing algorithms. Here we analyze The Efficient Routing algorithm and resolve horizontal constraints and minimize the net wirelength in a particular model of ...

Optimized Routing Methods for VLSI Placement Design

The VLSI placement problem is to place the objects into fixed die such that there are no overlaps among the objects and some cost metric such as wire length and routability is optimized. For this purpose A new routing method is used called , A Deep sub-wavelength lithography, (using the 193nm lithography to print 45nm, 32nm, and possibly 22nm integrated circuits), is one of the most fundamental...
